Okay, I got a buddy that bought a boat for $200 bucks. Well it floats and the motor runs but not full speed. I rewired the starting system minus charging system. Still starts like a champ, but at full throttle it has no power, wont even make a wake hardly. I know it's an older Johnson seahorse but the idiot before him painted the cowling and I didn't see any stickers with model or serial number. I am mechanically inclined and very confident in fixing the issue if I can get a manual for it. My question is.... where in the heck can I find a model or serial number on this motor if the cowling and motor is painted and no stickers are on it?
