    Mercruiser 4.3 LX Gen+, Hydrolock, no water in oil.

    agreed that would be very rare, on mine it didn't hydrolock it, just a small amount of water would seep in when it sat for a day or so. I was able to see the exhaust gas getting into the water exiting the stat housing via the hoses that feed the manifolds. If I checked for water right after...

    Mercruiser 4.3 LX Gen+, Hydrolock, no water in oil.

    Remove the oil fill cap and look inside. what a blown head gasket does.... first sign of this though was difficulty starting and rough running found water in cyl #2 and just a bit in #1 upon dis-assembly found both head gaskets blown right near a water passage near each cylinder water in the...

    Mercruiser 4.3 LX Gen+, Hydrolock, no water in oil.

    Sometimes what can happen is if the engine dies at higher than idle speed it can actually suck water back into the engine due to the vacuum developed in the exhaust system. Given what you just said, it is more likely that, (engine dying at above idle speed) than leaky exhaust. If it were leaky...

    Trailer Leafsprings Bottoming Out

    Your springs are too long. They come in all different lengths. Measure the distance between the mount flanges where the center hole is, that's how long the springs should be when measured eye to eye. When leaf springs are loaded they get longer. With the trailer unloaded your spring shackles...

    Mercruiser 4.3 LX Gen+, Hydrolock, no water in oil.

    If the gasket for the intake failed at the water passages it is more likely to put water right into the cam valley and into the oil. Water in the cyls might more likely have come from the exhaust system, do you have wet joint exhausts or dry joint? If wet joint it isn't that uncommon for those...

    OMC Cobra EFI 5.0L stopped and won’t start again

    My boat is always stored with whatever gas (e-10 is all we can get) was left in it but stabilized, stored outside in damp Long Island NY winters and I never see water in the fuel from the fuel filter when I dump it out in the spring when installing a new one. It is strange that you have this...

    1988 omc 5.7 w/ omc outdrive rookie service

    1) agree with Scott, the Qjet is an excellent carb when set up right, but one that age may need a REAL cleaning and a new marine grade accelerating pump. Also, my boat the same year as yours had a problem with the anti siphon valve when we first bought it causing a similar problem 2) you have a...

    Your fuse box might have extra pos and neg terminals where you can connect the radio directly to it, that's how I did mine, & the GPS unit.

    Yamaha with Water in Oil

    Agreed I’d probably change the oil & put a sample of what came out in a clear container, let it sit & see if you find a layer of water on the bottom. Also look for a mayo appearing emulsion under the valve cover(s). Both are evidence of a lot of water in the oil. If not if it’s only a little...

    noise coming from gimbal/coupler area after taking on water

    Ok guys Question Having driven off road on beaches for years and done more than a few water crossings (rain water not salt) in 3 different Jeeps all with non greasable ujoints & never having to replace one, what does that say? The oldest of these is 24 years old with 180,000 miles on it. As...

    noise coming from gimbal/coupler area after taking on water

    It would be interesting to see if the noise is gone without the drive on. Years ago (2004) my boat had water in the bellows at the end of the season & my mechanic pulled the drive & felt he could save the u joints (by thorough greasing) but changed the gimble bearing. Well all those years later...

    Gas tank access panel

    Mine was built with the access panel & I duplicated it when I re did the deck 15 years ago. These can be sealed with sealer to keep out water. My boat is always covered anyway when not in use so it never gets wet there. I had the cover off a few years ago & it looks good no rot. If you have a...

    Troubleshooting engine temp

    When the start chronically sticking and it won’t get over 120* F I feel like I have to get it right. Still have the old ones so can re test & see if they are still good. So Chris these boat are raw water cooled, in salt water all that time & no rust thru of the heads & block? I know when I...
