    Green gasket?

    Update. I used the silver looking gasket from Barr and so far no leaks. In fact the engine runs better than it has since first installing it two seasons ago.

I used a good quality straight edge to check for flatness and from side to side, it's good but lengthwise, I can see a little light under the straightedge which makes me think it has a small dip in the...

    Possible trim pump issue

    Is it normal for the trim pump to keep running after the drive is all the way down? It stops after letting off the switch but if I push the switch it will run. Seems like there should be a limit switch or something.

    New 3.0 in older boat

    Okay I installed a new GM 3.0L in my 2001 Sea Ray 180 and everything is ready to go. It runs but I am a little unsure of where to set the timing. Do I go by the manual for the boat year or should I go by the Engine year?
