    4.3L Water Circulation Diagram

    Even if u are not getting more water in you will need to change it several times to get all the contamination out. You can change only 3 qts or so then change. You have a good plan see what the pressure test tells you. If it holds he may have just gotten water in via condensation.

    NEED A VP PROS OPPINION!

    Nothing wrong with that combo if maintained. Lots of 5.0 and Volvo SX drives out there. Key is how it was maintained as that can ruin anything very quickly. Other key is your mechanical aptitude. If you can do some of your own work that is helpful given the age of the boat.

    4.3L Water Circulation Diagram

    You may have 4 lines going from thermostat housing to the exhaust manifolds and elbows vs what is shown in the schematic mike attached. The 4.3 originally in my boat has a serial number close to yours had that. No big deal just plug all 4 to isolate the block heads and intake for pressure...

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    Yes you should have returned it. Now you have seen enough chit you have to verify everything that was done. At this point you are probably better off getting a 4.3 out of a wrecking yard that is unmolested.

    I also have my boat with Progressive. Have yet to see any huge premium raises in years. Unfortunately if you don't regularly shop it around you screw yourself by being loyal. Biggest rip off I have seen lately is homeowners. Replacement cost drive those up

    Any Transom experts here. I have a Transom Rebuilding Question.

    In a word No ... use the merc thickness spec otherwise transom plate will not fit on and driveshaft will go that much less in coupler. 2 x 3/4 ply plus fiber glass on either side is fine as long as it is not rotted
