I've inherited Grandpa's boat & motor. The motor is a Johnson Seahorse 35.

Gramps always maintained it, and it was stored properly (storage oil in cylinders, etc). We removed the lower unit and ensured the water pump was good, and filled it with oil. It has good compression, very clean.

I haven't tried to start it yet, but that's coming this week.

I found three numbers:
On top of the engine: 0226884
Under the engine, on the body: 304812
In the top of the cowling: 376920

What year is this motor? 6 volt or 12 for electric start?

Thanks!

Re: Another "ID the Seahorse" question

look between the transom mount bolts, should be a plate there, or the quarter size round disc on top of the engine above the spark plugs. these numbers lead no where. i just refurbished a 1958 35 hp.

I found the plate... it was covered in grime so I missed it earlier.

Model is RDE-19, s/n is 226884. Patented Canada 1956.

Thanks for the quick response!

Re: Another "ID the Seahorse" question

for $140 you can change the coils,points, plugwires, condensers, plugs, impeller, and carb kit. at that point it will be like a new engine. the leg of the motor has to be submerged in water 1/2 up the impeller(water pump) is high and in not self priming. i use a large garbage can. my motor had a 135 psi compression. i also did away with the old style gas tank, and put a fuel pump on mine, so i can use the newer single gas line tanks. i sold my old tank for $80.00 on ebay, and paid for the major part of the conversion. it a really easy motor to work on. question feel free to ask.

I am currently fixing up a '57 35 hp that has been in a garage for 10 years. It's got close to 120psi each side so I expect good things from it!

Where did you locate the parts? I'm somewhat north of you, in Saskatoon, Canada (North of Montana).

Re: Another "ID the Seahorse" question

Nearly any new auto-type battery will supply enough amps for starting. The type you buy will depend on your use. I use a mid-priced Wal-Mart auto battery, but my use is typical day-use. I trailer mine and can recharge it at the house. Those 35's typically had no charging system, but a charged battery will do well for day-use(assuming the motor starts easily).

If, on the other hand, you use yours at night or over a period of multiple days, you might want to opt for a high-end marine starting battery.
