I need to replace the Starting battery in my Boat. I have a Galssport with a 75 HP Eveinrude Outboard.
Do I need a CAR type battery for a Marine Deep Cycly Battery for my Engine Starting Battery?

Thanks Tim

You need a marine starting. NOT a deep cycle.

Yes there will. You may have to go to a batteries plus. Not sure if advanced auto sells them. It will say Marine/Starting on the front. You need to pick the size/CCA necessary for your motor and your climate. For example, someone in canada may want a battery with more CCA's then someone who lives in florida.

On a 75 HP engine a "deep cycle" will work as well - especially if a fish finder, radio and other electrics are being use. One of our members uses a deep cycle to start a Big Block Chevy. Actually there are three trypes of marine batteries.

1) Marine Starting
2) Marine Deep Cycle (may also be labeled RV/Marine Deep Cycle)
3) Dual Purpose (Marine Starting and Deep Cycle).

If you are now confused more than you were before, go to any Farm Store in your area and check the auto dept. They ahve excellent buys on batteries. A group 24 or 27 starting battery can be had for less than 70 bucks. Even auto stores carry them.

Re: Batteries, Starting battery for Ourboards

These days marine starting and regular old car batteries are identical. The ONLY difference is the sticker on the front, and a larger price tag. At point some time way back in the old days, it was thought marine batteries were constructed to absorb vibration better. That may have been true at one point, makes no difference now.

I've run deep cycles as starting batteries before. On a 75, a deep cycle will crank that over without issue, and depending on how you use the battery, a deep cycle might suit your needs better. Its also a common misconception that you will damage a deep cycle by using it as a starter battery. You won't.

(got a deep cycle on my pontoon as the starting battery, with a 65hp 4 stroke on the back. It sees a fair amount of floating time with the stereo on. I'm going on my 6th year on that battery.)

You got threaded stainless steel studs for marine battery cables on those auto batteries?

No need to for the boats I own. I either have one cable only connected to the battery, or a clamp with a screw terminal on it. I refuse to have more than one 'thing' connect to each post of the battery.

I absolutely hate the marine concept of slapping a bunch of ring terminals onto a battery screw down terminal. Its far too easy to put the wrong wire back on the wrong terminal in the spring, especially if color codes aren't meticiously maintained.
