Vapor lock was common on the early MPEFI mercruisers, same as the early (pre-FCC) gt40's. A hot engine compartment would cause fuel evaporation on the high pressure side... No provisions on those motors to keep the hpp, lines or filter cool- the fuel return came back to the filter housing (not the tank) so add some heat and remove the flow and you get some heat soak/vapor lock. Experienced this on my 502 mpi, solution was to crack the motorbox after running. Not a great solution.
I agree about the heat soak on a carb engine... Smells like BS. Check the fuel inlet screen on the carb, I've seen those partially plugged and cause strange issues (not necessarily symptoms like running out of fuel). |

Hey Andy, His Sanger is an '88 DX with a 260 Mercruiser. Nice boat but it definitely could use some more ponies. It's either WFO or nothing for footing. Even then it only tops out about 40-41 with a footer in tow. A couple more MPH would be really nice. Gorgeous boat though. It had sat for some time because he gets pretty much all the skiing time he wants as part of the Gardens ski team. It just needed a good tune up which I did. Wires, points, plugs, cap, rotor, condenser. It would start and idle perfectly and we ran it around the lake for 15-20 minutes. It ran great. A week later he called me and said he was out driving a competitive trick skier. The boat ran great for about 30-45 minutes and then started missing really bad. It had rough idle, stumbling and finally die. He managed to get it back to the dock and let it sit overnight before he would look at it again. The next day he was amazed when it fired right up and it ran perfectly again for 30-45 minutes and the whole thing started all over again. In trying to get the boat back to the dock after one of these outings, he left the key on overnight which burned out the points and messed up the starter solenoid so I replaced the points again and replaced the starter solenoid.. I also removed, tested, cleaned and coated with NO-OX all the ignition wires from the starter switch, solenoid, starter, battery and wiring harness. I wanted to make sure that there were no wiring issues causing this problem. He had also loosened up the gas cap when this happened to make sure that the vent hose wasn't plugged. He removed and cleaned out the anti-siphon valve which was perfectly clean also eliminating fuel delivery issues. We were kinda baffled and I found a tech note online from Mercruiser about vapor lock issues on these engines. Mind you, I've never been a big believer in vapor lock as I've personally never experienced it so I was skeptical. We arranged to meet after work one day and see if we could get it to happen while I was with him. Remember, at this point I had not experienced any issues at all. I had tuned it and run it for 15 minutes and it had run beautifully. When I got there, he had everything cleaned out of the boat and the engine cover removed so we had no obstacles working on it. We beat the snot out of that thing for an hour and 20 minutes and didn't get so much as a hiccup out of it. It ran perfect with my only objection being it needs more ponies. The only thing I could possibly come up with was the vapor lock theory when the engine was installed. We found the air hoses from the deck air scoop to the bilge were rotted away and not allowing proper air flow through the bilge. I still contend that this single thing shouldn't cause vapor lock but what do I know. Then the next question is why would it now suddenly start to vapor lock when it has never done it before? To date, I haven't heard if he has had any issues since ordering new vent hoses but I don't know how much he's used it either. So that's the long winded version of what's wrong or what was wrong with his Sanger. WHEW!!!! |

Pete have you actually been working on the launch or are you thinking ahead on the prop? Start a thread on it if you have some wood working done please. I'd like to see what you're up to. In the "off Topic" section of course.

You should go with stainless, the flexing of the bronze prop when you channel those 15 HP through it will kill performance. |

You're the winner............................. when the prop is in your hand
Just out of curiosity, what do they charge for a special order for something like that? |

I already found the prop!! A Federal/Michigan Dyna-jet in bronze is a stock prop in both pitches. The DJ355 Federal/Michigan in bronze is my preferred choice and that model in both pitches is made to order with a lead time of 6 weeks. Cost does play a factor so I posted the need to see if a used prop will come up?? I do have some "feelers" out with my ACBS group as well. So, who wins the pool? |

Hi Pete
Now that you have a thread in the "Boat parts wanted" section I predict that you'll have no trouble at all finding your prop I figure you have more chance of winning the lottery and being attacked by a bear on the same day than finding your prop, but ya' never know. ..............after all the Cubs won the World Series this year so most anything can happen. Maybe we should start a pool to pick the date that Pete finds his prop. Day, month and year |

Ken, So, you pick on me and not Marty who was the second post!! BTW, Why would I put anything but a bronze prop on a 1915 boat with a 1927 engine? Got to keep it as close to original as possible!! |

Pete You should explore the site a little more. There's an area titled "Boat parts wanted". It's pretty easy to find. You should put your post there instead of hijacking this thread. Be a little more descriptive too, do you want stainless,nibral, aluminum, plastic or what? How many blades? How much cup? |

Pete, I'd think those were pretty difficult sizes to find. You're probably going to have to pay a big premium for those.

Tom, John and Eddie,
Thanks for filling us in on Rob. Yes, his introduction could have been better. My reaction to someone posting in all caps, slamming CC's ability to pull skiers and then stating his Malibu can pull 8, plus the obvious free business advertising got me off to a bad start. Rob, I do welcome you to CCfan, Fill us in on yourself as well as you prop business. Do consider becoming a site sponsor as it may be a good start to your business. |

+2 OK, this makes some sense now. I thought it may have been Rob when this first started out but wasn't quite sure. In Rob's defense he is a good guy. Skied many times with him and was even present at his wedding. I've worked on his Sanger and he was actually the one driving my boat when the extended plyon hit the bridge.....DOOOO (Sorry Rob, just couldn't resist...LOL). He just got into this business opportunity and is trying to make a go at it so a little slack goes a long way. In the CCFan's defense, I can see where Rob could have been a little better at introducing himself. We've had some not too pleasant experiences in the past with spammers so these guys are constantly on their toes and can be brutal to anyone who comes on here with even the slightest hint of trying to make a quick buck off of somebody. Getting in their good graces could make for a very nice relationship for everybody involved. |

Hey Propguy,
Come over and check out my Nautique bar! Guys, Rob (Propguy) is a great guy, and a super all around skier with his specialty being barefooting. I think that in my discussion with him on what to do with the spare props and parts I had, I mentioned I was probably going to offer them up on CCF, and I bragged about what a great source of info it was, even if he needs help on his Sanger Barefoot boat. Anyhoo, I know he has skied with a number of guys on this site, and he was/is part of the Wrecking Crew, so cut him some slack. You never know, he might have the prop you need! Tom |

Propguy, I"ll extend a much past due welcome to the group. As a rule most all of the members lend their own expertise to the group, be it in advice, knowledge, or a service. I am sure that you will fit into one or more of those categories. We even have lots that are just "lurkers" that soak up something from one or all of the above categories.
If you have a boat then be sure to list it in the diaries section as we all like pictures and stories. Duane |

In the words of Yogi Berra, this is like deja vu all over again.
I remember some guy named Eric showing up in about the same way as PROPGUY just did. He got a totally rude, unfriendly welcome from a number of people, hung in there, put up with the crap thrown his way and became one of the more liked and respected members on the site. Most people would have been long gone. Gave a lot of good advice, helped a lot of people with their problems. Even ole Pete thought he was the best tranny guy ever. Maybe things will turn out the same with PROPGUY Just my 2 cents |

Take a peak in the upper left corner of the screen and you will see the paid site sponsors like Delta Propeller. That is one avenue as HW mentioned or just hang out and be a positive contributor which would allow the members to get to know you.
BTW, don't mind Pete's Spam post, he has a tendency towards drama, lol |

One post is considered spam? I was posting/advertising because I was offering a highly needed service that I thought would be appreciated not condoned.
