nope...you want a good marine deep cycle batt. for your boat...also check the output of your altenator...if it's not charging....your batt. will supply the pwr until the batt. runs dry....

check all your connections...once started ..the Alt. should have kept it going....

Although you could make due with a car battery, a marine battery would be better. Boat batteries tend to take a physical beating - especially in smaller boats, from waves and wakes. Marine batteries are built stonger to take the beating. Also, check your existing battery connections/posts. Most car batteries do not have the threaded/screw on terminals that marine batteries do.

A deep cycle battery is a very good idea. Even better is a marine AGM battery. AGM's don't have liquid acid in them so they cannot spill. They loose almost none of their charge so they can sit unused for months at a time without damage. The down side is they are, of course, more expensive.

ok guys
the small (starter) battery was gone
left it sitting in the garage without a accumate over the winter
the big one is OK (but it needs a few days on a accumate)
bought a new deep cycle battery.
price was ok. (and doesnt matter/ don't need a new experience floating in the middle of the water without power again)

it does bother me that the engine died
i thought that the alternator would supply enough to keep it running but that would only work with a battery which is undercharged. not a deciesed one

another question
i have a power swith nob in the engine bay
it reads.
power off, 1, all, 2
what is nr 1 and nr 2 (which battery)

good new is that the engine started without problem after sitting for about 5 month's and the new prop is really an improvement (4 blade in stead of 3 blade)
thankx guys

batt.1 should be your start batt.
batt.2 should be the house batt...
