1971 25 hp Johnson 25R71S

I have finally found a bigger motor for my boat for a very good price. I am going to be getting it sometime next week.

It's a 71 25hp Johnson, short shaft, tiller handle.

1st question does the R in the model number mean remote steer/start? From looking over the parts listings it does not appear to have been made with the remote steer. But this motor has the 5 prong plug in on the front of the lower cowl for what I assume was a wiring harness. Underneath the hood there is the starter, but I do not see a solenoid. So I guess it was added later on.

If i can get a solenoid for this motor, is it possible to rewire the wiring harness plug in to be a push button start?

The motor starts and runs fine as is with the pull start, I would just love for the option of electric start.

Any help is greatly appreciated.

Here are a few pictures

R is for rope start. Apparently the e-starter was added later. You'll need the solenoid, and it should be easily obtainable at a salvage yard. I use tim's outboard 218-682-2331. They've never let me down!

also, you can go to boats dot net and find a zoomable schematic for your motor's electrical system. Good luck!

And jump the starter first before ordering parts in case the starter is toast.

Any idea what year range a solenoid would fit?

When you call tim's, have the model number handy. They'll know.

Wow, this tread is 2011!!! I'm wanting to put a starter system on my 25R71S also but putting that kind of money in it, not sure. I will call Tim's and see what he has to say.
