    Brass block drain plug leaking like a sieve

    I am thinking there is an issue between SAE thread and NPT thread. You can use Teflon tape on NPT threads. The adaptor mentioned is good but it reduces the diameter and chunks of rust can jamb the adaptor. So when draining the block one needs to stick a long nail all the way through the...

    This boat… always something…popping today

    Sounds like the place selling gas has an issue. I would notify them. Was the gas E10? If phase separation occurred the only solution is to pump out the old gasoline, flush the fuel lines and refill with fresh gas. If it's E10 it has up to 10% alcohol and that will absorb some water and that...

    7.4 L Volvo Penta turned into a milkshake - what to tell the mechanic

    I have watched some YT from Dave's Auto. He has a big repair and machine shop in Utah. He has a SIM tester where he can put an engine on and turn over the engine at various speeds to test it out before spending the time to install the engine.

    Hydrolocked VP 3.0 GSP-A

    With the engine running and boat moving, if people moved to the back of the boat that should not have caused the engine to stop or ingest water. I would try a compression test.

    7.4 L Volvo Penta turned into a milkshake - what to tell the mechanic

    The u-pull-it places have marine engines or a car or truck engine you would need to make into a marine engine. I think the cam is different and the mains are 4 bolt mains. I thank that kind of engine is only viable if you can do all the work yourself.

    This boat… always something…popping today

    It sounds like ignition. But first I would dump the fuel from fuel filter into a clean mayo jar and see if it looks like clean fuel or do you see water or other contaminants. Then go through the ignition. Look at plugs, wires, distributor cap and rotor.

    7.4 L Volvo Penta turned into a milkshake - what to tell the mechanic

    Pull the engine. Tear it apart. First figure out how the water got in and then examine the bearings and journals for damage. They should look pristine. Hopefully you will find an exhaust manifold. And not a cracked block. Were you boating in fresh or salt water? Is the engine FWC or RWC?

    Zinc contact points- sand clean?

    I am not sure the SS bolt provides the connection. I think it's the zinc touching the aluminum of the outdrive. The bolt just holds then in contact. SS is not a great conductor of electricity.

    Volvo penta 4.3 gxi rough running

    Your are either going to buy a Rinda Diacom now or later. Especially if located in an area where the bulk of boats are outboard. Few people to work on I/O. I bought a small Acer laptop and have two OBDII scanners for vehicles and Diacom for my VP I/O.

    Overheating AQ125a leaking cooling sustem

    Obviously you will need to order new rubber gaskets. I would stick in a putty knife and use a hammer to push the putty knife down and around the gasket surface area. It looks cast so too much force could snap a piece of.

    Engine replaced. Will not shut off.

    You need a wiring diagram and start to trace things out. I would disconnect all the wires from the alternator and tape them from shorting. Until you sort things out. But not good to be pulling cables with engine running if the alternator is connected. How many wires to the alternator? One...

    2002 Volvo 5.0 GXI Low Operating Temperature

    There are thermostats for raw water cooling and closed cooling. You need the right one for your type of cooling. Take the thermostat out and tie two feet of string to it. Heat up a pan of water with thermostat suspended in middle of the water. Use a thermometer to see when it opens. You...

    Water in bilge while on muffs

    Ok. That was it. I never pull the drain plug. But the marina pulls the drain plug when they pull the boat out of the water to put it on a rack. I was not aware.

    The basic block is the same but there are a lot of VP parts bolted onto the block. And of course the outdrive is all VP.
