    Motor question.

    big blocks have not been in a car since the 70's you can get a TRUCK motor, strip it down to short block and heads (pull it apart) and install marine head gaskets, brass core plugs. you will also need a marine circulating pump. then you can bolt on the marine accessory drive, rotating...

    Fluid Changes for Winterizing, Do I Need to?

    when I used to live where I needed to winterize, I generally fired it long enough to get oil pressure and make sure no leaks. about 3-4 seconds was enough for the gauge to start registering pressure then proceed to drain, pull batteries, etc.

    Fluid Changes for Winterizing, Do I Need to?

    if you did not use the boat at all (zero starts) then leave it. however if you started the motor even once...... then the acids start building up in the motor. these acids are a byproduct of combustion. the first thing they attack is the soft metal in the bearings an oil change is cheaper...

    Possibly Purchasing??

    being the boat is a 1989, I would definatly consider it a project boat. the price is a bit high, however Covid pushed the prices of all boats high the past year. I sold my 2002 SeaRay 190 for that $12.5k back in 2011 I would look the boat over with a fine tooth come. just looking at the...

    1998 Mercruiser 5.0 running problem - Camshaft???

    the fuel system is everything from the cap and vent to just below the carb. as stated, doubt its your cam shaft. you can pull the intake and look. then you are only out about a day and $100 for gaskets, etc. Im leaning toward improper fuel pressure........so measure the fuel pressure at the...
