    1989 Formula 26PC Twin Mercruiser 4.3LX, Alpha I, Gen 1 - Water Leak at/in Transom Assy

    I would not try to lift the engines myself, there's a lot that can go wrong with doing that, and the "wrong" can be really bad with 600 lbs starting to move when you don't want it to. Might look at it this way, how long will you keep this boat? If just a few years, try the repair you described...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Love the Alabama plate on the Chevrolet. Those trucks were everywhere when I was growing up. In our town in suburban Westchester NY, Ford was on one side of the street and Chevrolet was on the other side. My friend's dad was the Ford shop foreman so I got to check out all the cool cars they...

    Manifold & Risers no longer available

    The elbows for the Ford EFI engines are different, probably has to do with the mounting point for some of the EFI hardware, that is not needed on the carbed engines.

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    There is a lot of confusion over what OMC did in certain years, and a lot of the documentation is hard to find because they have been out of business for so long. So what I'd do is post up a pic of what you have, I thought they eliminated the overstroke switch on the later models and used an ESA...

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    The interrupt switch is normally open and the overstroke switch is normally closed. This is from my OMC shop manual: for the interrupt: After disconnecting the plug for the ESA behind the shift cable bracket. insert the test probes into the male connector plug (blue leads). Ohmmeter should be...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I think so, because there is no vacuum against the ball valve with the engine off.

    slight gas in oil 2009 yamaha 4 stroke

    You can have either fuel dilution or water dilution of the motor oil, or even both at the same time, to know which you have to do an oil analysis. Fuel dilution is probably more likely to over-rich fuel issues, such as a carbed engine with a sticking float, choke not coming off when it should...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    The only time the ball valve opens is when suction from the pump, pulls against the spring pressure. When the pump quits pumping the spring is supposed to close the ball valve to shut off the flow of fuel. Your question of what would happen if the fuel line leaked with the engine running vs with...

    Very difficult to shift into Neutral

    If you want your adjustments to be accurate: get the flex tool set it where it will run on land put the boat in the water then adjust the mixture and idle speed, because a marine exhaust system has back pressure that is not present while running the boat on land, and my experience suggests that...

    Merc 4.5, any reason I can't just dump the block and manually fill with pg antifreeze?

    Yep, my brother traded his 2020 Chap with the 4.5 I/O on a 2024 Chap with a Yamaha 4 stroke OB. I basically told him because we are in salt water sooner or later that one point drain will clog up due to the way cast iron corrodes, and then he'd have to clean out the drains which on these modern...

    Very difficult to shift into Neutral

    Yep that’s the only way with the Rochester style carbs (the Mercarb is a slightly modified Rochester 2bbl IIRC). The Weber/Edelbrock & Holley carbs are much easier to adjust.
