Last saturday I went out for a ride, did some barefooting, and then hanged in the river looking the city from the water. Then headed back to the marina... engine performed flawlesly as always, but from the last stop of it I started hearing a strange noise, like a blown exhaust gasket, so I lifted the doghouse while underways, and there it was this knock coming from the engine... WTF, boat idles fine no sound, I pumped the engine w/o gear up to 2500 rpm and no knock, only knock in gear starting to plane, around 1500-1800rpm and stays there. Engine starts fine without hesitation. No loss of power, no miss, no overheat...can´t say about oil pressure as the gauge broke a couple weeks ago, I grounded the sensor cable to the block and it didn´t peg. But after this I might think I had no pressure and maybe I toasted a rod bearing...oil pump was new when I rebuilt the engine. Other thing in play here, I started using fuel from a new gas station, this was my third outing using this fuel (put around 8 gallons in those fill ups)...so also made me wonder if this could be engine pinging due to bad quality fuel? advance is set to 10º. engine has only around 300 hours from rebuilt....so as you can imagine i´m really upset with this issue. I will go with my mechanic and friend who did the rebuilt to investigate some more, and let you know how this thing turns on...     ------------- <a href="">1992 ski nautique |

You need to KNOW if you have oil pressure before you run it again new fuel or not. I would also check compression before running it just because it is quick and easy and gives you a look at the plugs. IF you have good compression readings, good oil pressure, and your oil isnt full of metal filings then run it. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

yup I plan on taking a mechanical oil pressure gauge and plug it in place of the oil sensor... will do this on wednesday, as tomorrow the marina is closed... ------------- <a href="">1992 ski nautique |

Take it off, look at it very closely. You might see a very faint mark where it is arcing between 2 cylinders. If you have a new cap....you can throw it on. Happened to me...thought my motor was toast! |

Brian, I would be glad if this was the case, but this was no exhaust leak at all, this was coming from the guts of the engine... actually i´m dealing with a exhaust leak on the vette, as 1 manifold bolt made its way out and its blowing there, totally different sound... ------------- <a href="">1992 ski nautique |

I'm hoping for the best outcome, after having 3 bad engines in a row I know the feeling all too well. Hopefully it turns out to be something minor. take a long piece of pipe or a broom handle or long screw driver or a mechanics stethescope to listen and locate the source. Good luck. ------------- This is the life |

just came from the boat, I´m upset. Hooked the oil pressure gauge, 60 idle upon start and raises when you hit the throtle. I have low compression on #2 cylinder. around 60-70. rest is in the upper 150´s... Plug on that cylinder was destroyed, the electrode gone, though I got a pictures but no. Strange is when I got that out, after inspecting it I found traces of water in the spark hole...and some drips in the engine mount that sit below there. But when cranking the engine, no water came from there. No water in oil. Rest are fine. Knock is there under load from 2000 rpm and keeps there. on neutral you can no noise... So will need to start tearing appart that head and see first valve problems or what... Seems the knock if from the upper engine, and not from below as i suspected.... Really don´t know what could have failed...only 250 hours from rebuilt, all oil changes on time, correct plugs.... Mechachic blames barefooting and the high engine speeds as culprits (joking of course), but I really don´t think so. Probably will start the tear down by next week... ------------- <a href="">1992 ski nautique |

Well we will know when we know but heat/detonation/bad gas type issues is my best guess. You could have stuck a valve, dropped a seat, or cracked/blew up or melted a piston. A little too much timing and/or less than ideal gas can cause/facilitate any of those things. They can happen pretty quick or overtime at barefoot speeds and loads. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

good that you have oil pressure, maybe you have caught this in time to keep repairs to a minimum---stuff happens. sorry that you are having engine issues. its a bummer but keep your chin up and take care of business. I don't think you can blame high engine speeds unless it was over reving. 4500-5000 rpms really is not high rpms in the big scheme of things, pulling 1 footer is not over loading anything. bad gas? maybe, bad component? maybe. take a deep breath and tackle the problem. Once again very sorry, it sucks no matter what, it just sucks.  ------------- This is the life |

Knock under load, = rod bearing. With low comp on #2 and bad plug, rip the haed off - fix what ya find. Hard to guess, but when you pull the head you'll know.

What we talked on the phone today I also suggested Seb to take the valve cover off and move the engine by hand to see the valves open and close see if one's stuck or there's a bent pushrod. We need to find out WHY the plug burnt, and then head to see what else broke and WHY so it doesnt happen again. Anyway the head must come off and most likely the engine as well. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=2095" rel="nofollow - 1980 Ski Nautique Commander 351W |

That sounds like a good plan. That may tell more than just tearing into it. Just the fact that it is still rotating is a good thing. We had a Mastercraft way back when and it was bought brand new, it had a 200 hour warranty, at 211 hours we blew a hole about 1 1/2 inches in the center of a piston, had to replace the piston and we got it back up and running again. The theory was a lean condition. Later the whole top deck worked the pop rivets loose and detached from the bottom/hull. That was real special. That was when we went to a BFN. When the BFN had somewhere near 3000 hours we rebuilt it, on teardown the piston skirts were detached/broken off and being held in place by the rings. Willies Malibu detonated at 5200 rpms at 800 hrs and had major damages, hole in block from the rod into the water jacket...when I pulled the head there was no piston left the rod looked like a hammer had beat it for hours. Roy was driving and he said the sound was something he would not forget. I've got my fingers crossed that yours will be a fairly minor repair, you may have caught it before the real bad stuff has happened. ------------- This is the life |

today I was looking at the ngk plugs I had on the engine prior to replacing them with the autolite 764 around 6-7 months ago...I mark them from whick cylinder they came out. By that time they where all looking good, so the problem arrised in this last outings, probalbly bad gas @ wot.... i can´t work on the boat during the week ends, not permited by the marina, so probably till next week until I´m able to start pulling the engine appart... Only 1 week from this problem and i´m starting to suffer boat withdrawal symptoms.... ------------- <a href="">1992 ski nautique |

Kap, It could have been bad gas!! Last year I had the tips blown off 3 plugs from bad gas. Luckly my motor has a knock sensor and wouldn't let it go above I think it was 2,800 rpm. Long story short I would hate to think what would have happened if I was able to run it at full rpm. Oh by the way I was running Startron in the fuel at the time. I WON'T EVER BUY THAT CRAP AGAIN back to Stabil marine and no more problems. |

Kap that is bad news. At least you should have Bully there soon to help you with the spanner work. What rpm's are you pulling footing? I would check your total ignition advance at those rpms and maybe wind it a back a few degrees for safety with varying fuel quality. ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

just came from there... bitter... First pulled the exhaust manifold complete found rust on exhaust ports on #2 and #3 cylinder, so I undo de riser, and looks like the gasket was bad and leaked water into those cylinders after shut off. I will test anyway to see if I have a cracked water jacket in the manifold. Then removed the valve cover and all plugs and turned the engine. Valves close fine. Removed the Cylinder head...geez, found the problem..blown head gasket between #2 and #3. Strange as compression on 3 was fine. Little scuff on cylinder 3. Looks like at some point overheated @ wot (didn´t notice it) and voila failure. I´m taking the head to the machine shop to test for cracks and see the valve and seats on 2 and 3 cylinders.     ------------- <a href="">1992 ski nautique |

Could you put a large breaker bar/ratchet on the crankshaft pulley and give it a couple of turns and see if you see any erratic movement? Just don't loose track of piston timing/location. Or maybe with the starter? Be sure to disconnect/pinch off fuel going to the fuel pump. |

Interesting Kap. When I changed over to gt40p's I got everything together before I pulled it apart. I pulled off the old Felpro standard gaskets I had used and replaced them with PCM marine ones.Did not know what I was going to find on tear down and thought I'd be better off using the marine ones. The Felpro's looked fine and since you have them I'd use them. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Granted I have not personally heard the "knock" but other than a valve witness mark or something on the piston to explain it I am leaning toward your water in the cylinder trying to be compressed by the piston pushing water through the head gasket and bending the rod, or head gastet leaking first but either way a bent rod Causing the knock. Or a hot piston sticking could also bend a rod. Other than the labor pullin it apart there isn much reason not to at least check the rods ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

unless you want to do it twice...........funny, you always find the time to pull it apart a second time, make sure that not only they check for cracks but they check it for flatness, check the deck too...not to often does a head gasket go, without a reason, could be as simple as stretched, weak bolts, just cover your bases...I know how some mechanics can be....the famous cliche "it will be fine" which translates too, "on your dime" ------------- "the things you own will start to own you" |

no progress yet, yesterday I removed the other manifold to have the surface planed like the other, It came right off, only thing I busted a couple of knuckles in the process... I was looking at the gaskets I have at home to compare them to the ones I removed from the engine, they are all felpro, but they are different. This in the picture, the one from the intake manifold: the one on top was intalled and the one on the bottom is the one i will use to reassemble. Other than the larger middle hole for the acc? they are quite the same. Is this OK?  ------------- <a href="">1992 ski nautique |

The hole in the middle is a exhaust cross over. Some gaskets have that little plate installed. Some you install if you want to restrict the exhaust flow through the intake. One single plane intakes I've welded the cross over up. ------------- - waterdog - http://www.correctcraftfan.com/diaries/details.asp?ID=3896&sort=&pagenum=2&yrstart=1978&yrend=1978" rel="nofollow - 78 Ski Tique |

well ow you guys some update.. sent the head to the machine shop, and checked fine, had it resurface and cleaned. also had both manifold planed, all surfaces including the exhaust ports. finally I did not remove the engine, I turned the engine by hand and compared that all pistons would get to the max heigth, they all did. last week we put the head with new gasket and put the intake manifold. Today I went and finished intalling the rest of the things, valve covers, exhaust manifolds, new plugs, etc... fired right out, and went for a test ride.... relief no engine knock, at all, tried a couple of take off and nothing, look likr the engine is ok. Got to cruise a little hit the 3000rpm mark with no problem. anyway I need to do some tunning as i have a minimal bog upon take off, then it catches. Need to check timing or do some carb adjustment. I removed the plugs to check for water intrusion and nothing. Oil is clean, temp is fine. seems i need to give some more running time as all plugs came clean. ------------- <a href="">1992 ski nautique |

now seems like 1 1/2 month sleep, screwed up the battery.... or the timing needs to be set... on cold starts engine turns over fine, after the test drive when the engine was at running temperature, if I tryed ro restart it would crank slowly, then eventually start, but on a 3rd or or more restart it would crank very slowly. As I didn´t had the tester yestrday I could not see the volts. Today I went with the tester to take some numbers. Started with no problem, the alternator read around 14-15 volts, with peaks of 16. On the battery it read 12.06 volts...The conections at the battery were little rusty so I disconected and cleaned. Went for a ride again, 15 minutes. And went back to the marina. T was always between 140 and 160 degrees, probably low due to cold water... shut the engine, and again it cranks very slowly, it would not even start. let it cool some minutes and is starts, but on a restart is turns slowly... So either I have to much advance, or the battery needs some more time to get a full charge? Prior to the engine incident I had no problems... BTW engine runs smooth. Gary winter is cold but not as cold as yours, so I use the boat anyway. I prefer footing on winter cause less boats around, only hassle is the drysuit entry! ------------- <a href="">1992 ski nautique |

Check the base timing, sounds like its advanced. You had the dizzy off and didnt recheck the timing after reinstalling it? ------------- |
Posted By: Bri892001
Date Posted: June-01-2012 at 5:25pm

Hard hot starting would be too much timing or bad wiring/starter. You mentioned you have a slight bog on take off, but runs fine up top. I wonder if your distributor weights got stuck in the advanced position. |
Posted By: kapla
Date Posted: June-01-2012 at 5:33pm
|
actually i didn´t remove the dizzy, was able to remove the intake w/o touching it. Just had the conector unhooked. But yes timing needs to be checked anyway. The bog depends on how you give it gas, I you hammer it bogs a little then it catches, if you go gradually, it take off fine no bogging at all. ------------- <a href="">1992 ski nautique |

it was not the advance actually, the batery wasn´t charging at all, as you can see on my post I had 14v on the alternator and 12 on the batery with the engine running.... It would start cold after seating for a while, but after a few cranks it would loose power.... Today I went again to check all the conections from the alt to the breaker, it was all tight, anyway I rechecked every conection. Had to jump the batery to start the engine. Then took reading again, and now is charging. Let it warm, and did several restart and is now cranking fine. ------------- <a href="">1992 ski nautique |

Not yet next time out I´ll have it timed. But prior to pulling the heads it was properly timed and checked to 10º initial. Never checked full advance curve, but I would suspect its working properly, as the dizzy is fairly new. Other than the noise it was running strong even with 7 cylinders! I don´t have a ligth nor know how to use it so I have to take my friend to time it. Good news i´m not seeing any water in the oil or at the plug wells. ------------- <a href="">1992 ski nautique |

Seb, On the hard start ~ If it comes back (battery / alt / timing ok).... A bad wire connection (high resistance) will produce lots of heat. With a quick touch test, The one that that tries to burn your hand is the bad connection. ------------- Michael ....
