Circuit breaker

[Oldboat61]

I have a 94 stratos 254 I need to replace the circuit breaker on the battery connection wire. Can anyone tell me the correct amperage breaker ?

Would help to know what motor?
Is it the main feed to the helm or somewhere else?

50 hp Yamaha and the breaker is attached at the battery positive side. All the markings are faded off.

I don't know, I would hope if this was posted in the Yam section one of those folks might know. If you know what size your alternator is may just go maybe 10 amps higher
