Re: 1967 Seahorse 3hp wont rev up
Compression test should have been the First thing you checked. Yes, it might have a spark plug wire arcing through where it is clamped to the bottom of the armature plate. In really tough cases, a resistance test of everything is a good diagnostic tool. I don't see where even a spark check was ever done, but maybe I missed it.
Flywheel torque is 30-40 foot pounds, although some manuals state 40-45. Well at least 40 gets it both ways. Use a strap wrench to hold the flywheel instead of the propeller. Besides, the pin is supposed to be stainless steel , not brass. Part number is 203230.
All righty then > I replaced the coils, points and condensers and it still runs as it did before.I also broke the brass pin in the prop hub trying to get the fly wheel torqued on. My next guess is shear pin for prop,spark plug wires and checking compression correct? Anything else need to be looked at before doing this and in what order? Im having a tuff time navigating and finding parts on this site for the year I have:Thanks JONESN
