    Battery/batteries in the bow?

This is a 17' ski boat with a closed bow powered by a 77 115hp Merc outboard. I am still deciding if I will be using 1 or 2 batteries on the boat, but was...

    Stringer question...85 Checkmate ski boat

    I am looking at an 85 Checkmate ski boat as a project and had a question regarding the stringers. I know one of them has rot and the other seems OK, at least it does where I can get a look at it without ripping up the floor, but I will assume it is bad as well. The floor is a bit soft on the...

    Will a 77 115 run with a dead battery???

    I have a 77 115 horse motor with thunderbolt ignition. Will this motor run on it's own if hand cranked to start? I know running this motor with no battery hooked up will fry the rectifier, but what would happen if the battery is hooked up but dead? Will the stator supply enough...
