I just bought my first bought, a 88 Ski Nautique. What is the best way to run the boat out of the water. I was told to hook the hose up to the engine flush connection in the back. Is this correct?
Thanks for any insight. ------------- Wakemeup 1988 Ski Nautique 1999 Air Nautique |

Thats how Ive always run mine BUT it is not the correct way
To Quote Gary S The trouble with running it at home on a hose is that your putting your house or city pressure on that pump.Get a piece of hose to extend your intake hose and put in in a bucket,letting your hose from the house fill the bucket.Then see if you have a leak,you'll also see how good the raw water pump works also. |

Makes sense to me. I wonder if a pressure regulator on the flush connection would help like the ones you use on an RV when hooking up to domestic water? It might restrict the flow to much. Anyway, I will have to find the hose your talking about see about extending it.
Thanks for your response. ------------- Wakemeup 1988 Ski Nautique 1999 Air Nautique |

| The hose should start at the pick up in the hull,then go to the raw water strainer and into the trans cooler,you could attach it at any of these points. |

| If you plan on flushing the engine often you could install a FlushPro. I boat in salt water so I flush my engine using this after every time I go out. I have been very happy with it. Here is the cheapest one that I have seen: http://www.skidim.com/prodinfo.asp?number=DP6 |

Not to doubt you Tow,...but where are you getting your information. Skidim sells the Flush-Pro and it can't be used by drawing water from a bucket. ------------- 95 Malibu Echelon w/Mercruiser 350 Magnum Skier Former boats: 88 Ski Centurion Tru Trac II 59 Chris Craft Capri (woody) |

| Brian That quote is from a sting here on overheating.I would think if you hooked a hose from either the strainer intake or the thru hull pick up it would flow thru the flush pro the same as the raw water would ????????????? |

Wakemeup,
Back to your question. I do not believe using your flush connection (I think CC knew what they were doing) or hooking a hose up to the RW intake hose hurts the boat. It's an OK way to flush or test your boat in the driveway. What people are getting at, I believe, is that you can have a bad raw water pump and you would never know it if you use a hose, because the hose pressure forces the water through the engine. I am sensitive to this as I had that exact problem and didnt know it because I always hooked up a hose directly. So I pretty religiously use the "bucket method" now. However, now that I know I have a new and good RWP, I would not shy away from periodically running with a hose hooked up if I had some quick testing to do in the driveway. ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

I too have a new impeller and have no overheating trouble. If I just want to start it to check before heading to the lake, checking timing etc. I'll just hook my hose to the Flush-Pro. Beats disconnecting water hoses. For troubleshooting heating issues,use the bucket method.
I guess we can ask Eric if there is a reason to cool trns fluid while running the boat in neutral, which will not happen with the flush pro unless you install it before the trans cooler. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1657" rel="nofollow - My 88 Nautique |

Why do the http://gator49.hostgator.com/~zeromyst/catalog/images/flushpro.pdf - Flush Pro Instructions say to put the water on 1/3 pressure, start engine, then increase to full pressure? Why not just full pressure from the beginning?

If I had to guess it's because your raw water pump is not turning with the engine off and the water pressure will force itself through the impellers. Don't see how that would hurt them though. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1657" rel="nofollow - My 88 Nautique |

75Tique, I think that basically answers my question. I'm not necessary looking to flush the motor. I am just adding new parts, i.e., rebuilt carb, distributor, etc. and want to tune it in the driveway. So it sounds like using the factory flush hookup is OK for this purpose. However, I would like to check my RW pump like advised. Thanks for everyones advice. George ------------- Wakemeup 1988 Ski Nautique 1999 Air Nautique |

1990 Ski Nautique, Ford 351 OK I get that I have to connect a hose to the intake (I'll do it before the raw water filter), but will a standard garden hose fit?? Also - I see a connection at the front of the block, near the raw water pump, that has a standard hose connection and a shut off valve. It's near the bottom of the engine. My father in-law (owner) told me to connect here, but how can water flow through the system this way (bypassing the raw water pump and engine block pump)?? ------------- Rob. 1990 Ski Nautique. |

Fought my way through Perko's first line 'technical support' today and got a guy that sounded like he knew what he was talking about. He said that procedure was to prevent water from backflowing into the cylinders. Can you guys think of a way water could backup? I can't picture in my mind how high an Invert-A-Flow is in relation to the risers but figure not high enough. fyi in case you guys come up with a way this could happen - he said in addition to running the water slow until the engine was started one should not run the water for very long before starting and cut the water off between starts.

robe, sounds like you've got a flush connection up there. Go with it. Eric says your tranny won't heat anyway. You'll just want to make sure the pump is picking it up and bringing it thru the engine. ------------- Mullet Free since 93 http://www.correctcraftfan.com/diaries/details.asp?ID=717&sort=&pagenum=1&yrstart=1991&yrend=1995 - 95 Sport |

Im still confused why everyone makes a big deal out of this. Why not add a simple tee in the intake line before the RWP? For $15 in parts from Home Depot, you can connect a garden hose in less than 5 seconds. Its one of the first things I add to my boats.
Run the hose full blast- excess water pressure will drop right out of the intake grate. Even with the best water pressure, you probably wont feed the pump 100% of what it wants (it will suck some air) but who cares? Theres plenty of water being sucked in to cool the engine and keep the impeller lubricated. Its not the best set up to test the RWP (since it forces some water in), but for flushing the engine or running in the driveway, its perfect. Simple, cheap, effective. ------------- |

Tim the reason I wrote that was that gentleman had a leaking circulation pump and I believe he was compounding his problem by applying house pressure.I myself am a little leary of using plastic fittings and strainers with out a shut off on the thru hull tho- ------------- 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 |

Gary, youre absolutely right- Id be a little leary of forcing water through the cooling system at high pressure. Thats one of the benefits of the simple tee. The bucket test you mentioned is definitely the way to test the effectiveness of the RWP. As far as the plastic fittings go, Im not too worried- we've had set ups like this on our boats for a long time. The plastic elbows on the strainer are factory (and have been since the mid 80's). My dad's '03 has a shut off valve, but it seems to be more trouble than its worth- he's already fried one impeller because of it. ------------- |

Do you put a valve before the "T"? If not, how do you keep the water from pouring out the inlet? I have the Flush Pro on mine. It automatically shuts off the supply side from hose pressure.

Nope. I dont keep the water from pouring out- that allows the excess pressure to flow out the intake grate when the engine is off. When the engine is running, very little water comes out the grate. ------------- |

That makes a sense TRBenj the impeller would provide enough resistance to force the water out the intake grate until the motor was started and the RWP started to suck. I have always put a non return valve between the "T" and the intake grate. The valve is the most expensive piece to buy and I have often wondered if it put any restriction on the quantity of water the RWP could suck through it.
I always make sure the water pressure is not excessive before connecting to motor and starting the motor as soon as it is connected. The removal of the valve saves any worries with those issues. So out comes the non return valve!! ------------- 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 |

it's funny that you believe that hose pressure is enough to bend the vanes and allow water to enter the motor while it is not running and you allow for a lot of air to enter into the system due to the turbulance created at the tee where one side sucks air and the other water oh well EE's have all the answers to bad most electroincs are air cooled and not water cooled. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Tim you got me laughing here,my dad did the same with his shamrock,I imagine you do it only once! That is also the advantage of the shutoff,you don't have to take the boat out of the water to change the impeller  ------------- 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 |

In 1979 I bought first Correct Craft it was a 1953, I have had around a dozen over the years, I now have a 1982 with a 351. I learned somewhere over the years to get a female garden hose end and mount it through a standard toilet plunger (preferably unused). When you are ready to hook it up and use, you cut the handle so it will hold upright over the water intake with pressure against the hull. It has to have enough pressure to hold it in place with water flowing. Test it by hooking the water up and running it. In all the Correct Crafts I have had, this has never let me down. ------------- Martin |

This is a little more complicated then fittings, plungers and valves but always worked for me. It also allows me to see how well the pump is working. |

Martin, What model was the 53? Any pictures? A toilet plunger and even a puchased "fake-a-lake" plunger is difficult if not impossible to use on through hull recessed pickups in later year hulls.

Here's another "different" way to run your boat out of the water. No plunger needed. Nothing needed actually. I won't mention what state this guy is from, otherwise Pete will probably dig up somebody doing something stupid with their boat in NH. And......that would probably be pretty easy to do |
