    1986 seaswirl nightmare

    There is no way anyone can answer your question with what you’re providing. What OMC drive? Stringer or Cobra? The boat is a 1986 it could have either. It’s 37 years old; you may as well accept that to make it reliable you WILL be putting thousands into it. No one here with a boat that old...

    Trailer driving lights do not work, what I've done so far...

    They make led trailer light receptacle testers that are nice to have, I made up a couple of 4 flat harnesses for my trailer with this built into the end of the harness so you can see if the trailer lights are getting voltage without walking around the back of the trailer.

    VP 4.3GS Carb Tuning Vacuum Port?

    I heard of doing it that way back in the late 70s but never actually considered doing it that way. My 4.3 doesn’t really have an easily accessible manifold vacuum port so I just use the tach & get the highest rpm between the lean & rich roll points.

    VP 4.3GS Carb Tuning Vacuum Port?

    Rich running is common on Holley carbs, one of the causes is that the throttle blades at idle are too far open, exposing too much of the idle transfer slot. That slot should be a square shape, as seen from below the primary throttle valves. At idle you want it pulling fuel only from the idle...

    If you have a roller trailer used in salt water....check this....

    There are 2 pump out boats that are both Whalers over in Huntington Harbor and both have been on roller trailers for years.

    If you have a roller trailer used in salt water....check this....

    While Four Winns also sells all their boats on a factory bunk trailer, the dealers here give you a choice, and most use the roller. We have had a few hurricanes come up the east coast and I was glad that I had the roller that gave me the freedom to pull the boat when I needed to, instead of...

    They’re lakes Lakes don’t have tides We have tides If you don’t pay attention to tides you WILL be aground. My brother was a lake boater now he’s in Long Island with me so I taught him about tides. And why he can only use the deep town ramp with his bunk trailer.

    If you have a roller trailer used in salt water....check this....

    I know that no one uses roller trailers in the south or on most lakes but they are much more common here; so people have to be aware of their local conditions. If you listen to internet opinions with no knowledge of your conditions then you can wind up with smithing that won’t work for you. LI...

    I've sprung a leak! Help Please!

    If you use West System epoxy they have slow hardeners that can be used in warm weather. You have to be careful & not mix up too much at one time because the mix can get REALLY SMOKING HOT. 209 extra slow hardener. I’m used this when I had to fix some rotted wood in the engine compartment one summer.

    4.3 cooling

    If the belt is jumping the possibilities are a bent or loose pulley, bad harmonic balancer or a bad tensioner or even a bent bracket.

    If you’re boating in lakes & have a good steep ramp then no issue with a bunk. If you’re in a costal area where the tide swings are 1’-2’ and good steep ramps same thing. If you’re on the east coast mid Atlantic to New England with 6-8 feet tide swings and a steep ramp, OK to bunk. Shallow ramp...

    My boat is being a boat . . .

    I recall the last time we went to the NASCAR race at Pocono Speedway about half way through the race woman stood up and comically howled “Oh my God I think we have run out of beer!” That was back in the day when beer drinking fistfights were common at NASCAR events….

    My boat is being a boat . . .

    We have a real economy boat. A 10’ Walker Bay dinghy with a Suzuki DF2.5. You can run all day on a gallon of gas! Just have to stay in the protected bays.

    If you have a roller trailer used in salt water....check this....

    If you peruse your trailer manufacturer’s part’s catalog you might see that there are different roller bar & crossmember mounts that allow you to lower the boat on the roller trailer. The way they come from the factory is not always optimal. I was able to lower mine approx 2” this way. I could...

    help, new fuel pumps and pressure still below specs 2004 5.7 MPI

    What I said. I recall reading that Merc revised these cool fuel modules because of problems in the field, I wonder if that has anything to do with the OPs problem of low fuel pressure. Are you sure that the parts used are correct? Also while there may be 12v at the connector what happens when...

    My boat is being a boat . . .

    I have a 15 gallon gas caddy that I bought right before Hurricane Sandy but no way am I lugging that thing out to the mooring. The best gas cans I have found for filling boats safely are the VP vented racing cans with the optional gas spout. Expensive but worth it.

    help, new fuel pumps and pressure still below specs 2004 5.7 MPI

    Other than low voltage to the pump and low fuel volume to the pump if everything is new with the correct parts installed what else causes low fuel pressure?

    help, new fuel pumps and pressure still below specs 2004 5.7 MPI

    A 2004 boat is old enough that the anti siphon valve could be bad, fuel pick up screen clogged etc. Ever try testing pressures with a remote tank? I’d for sure do that before pulling the engine again. It’s stories like this that make me glad I still have a simple engine with a mechanical fuel...

    Different strokes for different folks. If you have 6-7 feet tidal swings & shallow ramps the roller is the only way unless you restrict yourself to the (2) high tides each 12 hrs. Damned inconvenient!
