boat question, battery info

[szabi]

Hey all,
I have a quick question.I recently bought a deep cycle battery for the boat, I got the downriggers and motor both hooked up to it but I heard I shouldn't use a deep cycle to start the motor.
I had to boost it last time I was out there and would like to hear others thoughts on this.

I'm going to buy a separate starter battery just for the motor but was wondering what your guys preferences are. What kind of charger should I get with it.

Also, the motor seems to at times choke and as soon as I prime the ball, away she goes, would that have anythin to do with the battery or is it sounding more like a carbeurator issue?

Any thoughts ?
Its 1967, 65 HP merc thunderbolt.



Thanks In advance

I am no expert, but I have always been told that a starter battery will crank out a big charge til the end, and a deep cycle lets out the charge a more "mellow" rate.

One is designed to start the motor with a kick the other is to power items as mentioned.
