Hey I have a'67 Johnson Super Seahorse it has 33hp. I need any information that can be useful. It doesn't matter what it is I can use it. Thanks.<br />Cien
Some of the internal parts like bearing, rods, and stuff like that might be a little hard to find. Had that problem with my 25hp 1973 model. But used parts ar plentiful.
Your motor is model RX15 3 1/16 boreX2 3/4 stroke<br /> 40.5 cubic inches.Plug gap .030 point gap .020.<br />50:1 fuel mix.<br /> Though I dont know this as fact it appears it<br />shares some power head components with the 56-60 35 hp motor.B and S /displacement are the same ring clearences appear the same.The carbs are of OMC design.Napa auto parts carry some parts for your motor.
