Can I use a car battery I have laying around as a starting battery for my 93 Evinrude 120? Thanks!

Prop....with your info first thing that comes to mind is u have a hot wire that is touching the inside hull of your boat draining your battery. And just in case u doubt it, be warned, I have a friend who bought a brand new alumacraft and was having the same problem as u are. Alumacraft wired the boat wrong long story short, so the unthinkable does happen. Look at your transom, look for small pitting indicating electrolysis, if so, u got a hot wire that is exposed and touching metal Edit...check voltage regulator on motor also

My starter battery this summer goes down after it's been running for awhile. Gauge drops and the alarm will sound. Battery is always fully charged and even bought a new one couple months ago, same thing happens. Any ideas what could be draining it?

here's a pretty good answer to the differences between a marine and auto starting battery... boils down to usage and construction

...bottom line, you can use your auto battery, but it's not really made to perform like a marine battery

get adaptor terminals and use it till it dies. no sense letting a good battery go to waste if you have no other use for it.

Ed good point on the sudden jarring that a boat battery typically takes!!

It will work.. However it is not made to take sudden jars so the life is not as good. I would get a marine starting battery as they are not all that expensive. Not a battery expert just telling you what I have been told.

Good question. I imagine that you could as long as you are using it for a starting battery only. However keep in mind, car batteries typically have a post with the clamp being on the wire, where marine batteries have a much smaller post with a nut on the battery post to keep the wires one.
