Can anyone advise me on how big of a circuit breaker I need for my 1986 25hp Mercury. I bought it used with a 50amp breaker on the battery but it seems to break an awful lot when I start when it is not warm yet and it takes a few seconds to start. I cannot find anything on a size breaker for this anywhere.

I know why you cant find info on it. They don't generally have circuit breakers on them. I have had mercs, yamahas, evinrudes, in tiller, jet, prop etc. and NEVER had a breaker on my main battery wires. I say just scratch the breaker. If you really want one put a 100amp on there and be done with it.
P.S. I actually just got rid of an '87 35hp Merc that had the wires run right to the starter and solenoid, no breaker.

No breaker here either. Just make sure you use the recommended AWG size wire and you should be good.
I had a old johnson one time that was missing the harness for the electric start. I was advised by a mechanic to get a selenoid for a ford and he could make it work. I sold it before I ever got the chance to try it. Just a little. 02

No breaker needed... Solenoid does the job...
