Re: 35 hp Johnson sea horse
An original OMC manual is
"Johnson Service Manual Tenth Edition"
that is correct. i have the manual.
it is a dependable motor, check you compression and spark. to see if you have a viable base to work with. to be dependable, you will probably spend in the range of $200 to change, point, condensers, coils, plugs, and wires, carb kit. a must do is to service the water pump.
it is a simple motor to work on, if you are mechanically inclined.
good luck, and post any questions.
