    Did you check the gas tank vent & the anti siphon valve? With fuel system problems start with the basics first.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    https://www.michiganmotorz.com/5-8l-351-ci-ford-marine-engine This with a nice Holley 650 CFM carb would wake that boat up. Not sure what a Four Winns Sundowner weighs but I can tell you that my Four Winns 20' bow rider weighs in at 4200 lbs. Mine has a 4.3 V6 which is just adequate, it should...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    When you slide down the rubber hoses on the exhaust Y pipe, you can tell if there were flappers originally installed because there will be 2 holes on either side of the upper end of the Y pipe. If these are filled with silicone sealer someone did the V/P service bulletin and removed them. If...

    Reliable sure lube hubs

    If you haven't owned this long then I'd take it all apart and inspect the bearings, races & seals, if replacement is necessary that's good time to do it. Otherwise beyond spinning the wheel and listening for bad noises, vibration & play etc. there's no way to know what condition they are in.

    Reliable sure lube hubs

    I had these on my original axle on the Load Rite; the grease goes inside the axle tube.

    My boat is being a boat . . .

    I could see if the pressure cap is allowing enough coolant out that you could wind up with a small amount of air in the cooling system that alone could cause the slight increase in running temp.

    My boat is being a boat . . .

    That’s really not overheating though & when our Subaru overheated both times it pegged hot on the gauge. My boat even when the HGs were leaking never really overheated, it really depends on where the HG failure is.

    Looking at a 1987 Bayliner 2160 Hardtop ???

    Agreed on both points frankly ANY 1987 ‘glass/wood composite boat is a risk for rot and a 3.0 in a 21’ boat is less than adequate. I have the 4.3 4bbl V6 Cobra in my 20’ FW and it’s adequate for a cruise speed of 25-30 mph but that’s about it. Ideally it should have a 5.7 4bbl. The Cobra drive...

    My boat is being a boat . . .

    Ted I would think that with the low hours the thermostat and/or pressure cap are much more likely causes. You could do the clear hose test (replacing the hoses feeding the manifolds/elbows) to see if there are air bubbles in the coolant; or alternatively you can get one of those combustion gas...

    2012 5.0 Ltr. MerCruiser overheating issue

    I’d do the clear hose test to check for combustion gas getting into the cooling water from possibly leaky head gaskets. Temporarily replace the hoses feeding the manifolds from the thermostat housing with clear reinforced hose. Ideally test in the water & run it at idle & on plane while a helper...

    Help with OMC/Volvo 3868156 joint venture outdrive shift cable please

    Unlike the original OMC Cobras these do not use a gasket between the pivot housing and the drive. The seal is made by the bearing carrier pushing into the outer edge of the bellows. The shop manual for the Cobra says to coat the inner lip of the bellows and bearing carrier with triple guard...

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    PS you might consider posting this up on the bayliner owers' board, someone there may have the same boat, might know better. www.baylinerownersclub.org

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    The only way I can see of doing it MAYBE is to support the engine from above using the lifting eye on the starboard side of the engine (you can see it in the pic) and lift it just enough to take the weight off the mounts and remove the mount. But, that is risky to say the least and I'm not sure...

    Quadrajet Secondaries Problem

    We all have limits in terms of what's the best service we can find for whatever we like doing, however there are certain things that just don't make sense, not getting rid of old gas, is one of them. Ask a tech rep from Mercruiser if you should run a boat on 3-year-old gas and I bet you they'll...

    4.3 mercruiser vs vortec pistons

    375-17210 Keep in mind this comes with the intake gaskets for the pre Vortec you’ll need to pick up a set of Vortec intake gaskets. I believe the head gaskets & exhaust manifold gaskets are the same for both.

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

    I've seen that on a few trailers (bent roller bar) over at the local marina. Not sure how it happens, other than the boat may load in such a way that too much weight is going on the front roller bars and the rear still floating? Angle of the trailer when loading? Who knows.... Yep once you see...

    Mercruiser 4.3 Alpha One problem - loses power

    Your main fuel filter is in pic #2, extreme lower right, the round housing you see there, the large water separating fuel filter should be screwed into that housing (below what you see in the pic) it is large like an oil filter. Some Mercs had the pump with the filter built in but you appear to...

    5.7 GXI-H engine. Alternator problem ?

    Isn't there also an S terminal (Voltage sense)? I know the older Volvo set ups had the Excite, Sense and Voltage output terminals, and on some the Sense was simply connected to the Voltage output terminal with a short wire.

    4.3 mercruiser vs vortec pistons

    I would see if you can get a Fel/Pro marine head gasket set for the 4.3, in the USA they are about $120 or so, the head gaskets are the same for the pre-vortec and Vortec, you would just need to get the Vortec intake gaskets those just use the best ones you can find, I don't know that any are...

    That, or a REALLY GOOD classic car restoration place or a speed shop. Here on Long Island we have SK Speed in Lindenhurst NY. https://www.skspeed.com/ When I go here to buy stuff I’m in hot rod heaven. As a kid I grew up watching street racing in Brooklyn NY everyone knew how to rejet a Holley...
