    Bad Fuel Pump?

    I've chased an issue and I think I've arrived at a bad fuel pump. I was out recently testing the boat after I had recently redone the gimbal bearing/bellows/gaskets on the outdrive, and the boat sputtered out and died about 100 yards out of the marina. I tried to restart many times, the first...

    Water in Bravo III trim fluid

    Discovered water in the trim fluid after it started acting funny when trying to trim it up/down. Trying to figure out where the leaks usually come from in these and if it's something that is just a matter of changing seals, or something else. Anyone know where to start on this?
