    Open or thru hull

    So with the new boat. 496ho with Silent choice. I do a lot of cruising mid to high speed long distance sometimes 1/2 hour or more at a time. Should I be in silent mode for times like this? Just wondering if having it is straight through if the lack of back pressure would effect the engine after...

    What to use to cover multiple finishes

    Time to refinish the old girl. Starting with a 1993 250 CR Crownline. Black in color. At some point in her life she had been hit on one side and repaired with a real crappy I think paint job. The gel coat side is spider cracking and severely chalked. Well beyond buffing. And it wouldn't matter...
