    I've got a good idea how to do this, but... check twice do it once... I'm having to move my gas vapor vent, leaving me a hole about 3/4 in diameter. Obviously I'd like to fill it now while my gas tank is out! Plan is from inside, taper the hole, tape the exterior hole, fill with PB and some...

    Manifold drain plugs leaking...

Do these things go bad? Had the boat winterized, etc. Plugs appear to be a "butterfly-style" screw which screws into...

    Re: 1975 Crestliner Trihull w/ 3.0L Mercruiser - New Project Pardon the crude drawing... along with other things I need to figure out, at higher speeds, the boat does this while still going straight: When I throttle down it levels back out. Trim adjustment? Thoughts? I was pretty well...
