    Change or replace toilet?????

    I have a 1991 Jabsco manual flush toilet in my boat. The manual flush plunger is not working properly. It will not suck in the lake water at all, but will discharge the toilet water (filled with a bucket) into the holding tank. It is also very difficult to operate the plunger handle. Feels like...

    Exhaust Elbow Replacement

    My 1991 350 cu.in. Mercruiser is due for new exhaust elbows. Would it be wise to purchase original Mercruiser parts or aftermarket exhaust elbows. I plan on keeping the boat (1991 Doral 255) for a long time. Your thoughts are appreciated..........

    exhaust manifold overheating

    I just had a marine mechanic install new exhaust manifolds on my 1991 5.7 liter Mercruiser, which is sea water cooled (Lake Michigan). He made a mistake by using the wrong metalic gasket (the solid gasket for closed cooling systems) on the port side (he used the correct gasket on the starbord...

    I'm considering purchasing a 1988 Carver Montego equipped with twin 4 cyl. Mercruiser's @ 171 H.P.; the boat weighs 6300 pounds. Will the twin 4 cyl. engines have enough power to cruise at 25 m.p.h., or will the boat be underpowered? :confused:
