Cranking amps

Possibly have to replace my starting battery. Not sure what size/cranking amps I need. Got a 115 Yamaha

Any suggestions?

Ya got the manual for the motor? It should tell you! My F225 takes a 750CCA. Is the old battery the one that came in the boat new? If so, I’d just look at it and replace it with the same CCA size! I looked it up for you!

Thanks for the chart. I took the battery out and had it checked. It checked out ok. I must have something running the battery down. I can charge it and go back to it in a week or two and it will be weak/dead.

Battery disconnect is your friend. Surprised an 18’ Hewes doesn’t have one.

I have a disconnect switch ready to install. Have to correct a problem in the motor first. See thread about motor diagnosis.

Thanks
