What size battery

[dofunny]

I have a 73 or 74 model 115 evinrude with manual shift. When am in the yard flushing the engine out motor starts good every time. When I'm in the water riding for about 15 minute and stop to shut it off its hard to start and it will run my battery down. I have a hapa marine battery in it and I use the same battery for my inboard boat and it does not die.I don't know if the battery has enough amps for that motor or do I have another problem.<br />Dofunny needs some help.

Re: What size battery

I don't have anything to check the tempature with but I have felt the cylinder head in the back with my hand and it was not hot to touch. Just the other day I put the flushing ear on it and ran it for 5 or 6 min and took the boat to the river and it would not start. The battery die on me.
