What size battery would I need?

[NatedoggAZ]

Have a 1988 Sea Ray Seville - here are the details:

Located in Arizona
175 Horse Power
4.3L2 V6
Engine model: 443S100AR
Terminals are set up for top mount

I do not have any trolling motors or crazy stereo systems that will be run all day with the engine off....
Not sure if I will need a crazy high CCA battery either since it will almost never be "cold".

Thank you!

Manual list 375CCA, 475MCA rating as minimum.

I would suggest get the largest bat that will fit in the battery box. Never found anyone that wish they would have bought a smaller bat, when they need to crank it some to get it started

I had an '88 Sorrento (sister ship) w/ a 4.3LX. I ran a single 27 series battery, and never had an issue.
