dead batteries

[liar_1999]

i have a 55 hp 1972 or 1973 chrysler outboard , it runs very well the only problem my battery will go dead after about 5 or 6 restarts can anyone give me feedback in what they think it could be !!sometimes it will go dead after going full boar around the lake any ideas is there a recharging system on this motor that might not be working???

Re: dead batteries

Off of a good battery you should be able to get way more than 5 or 6 restarts. How is old your battery? Deep Cycle Marine 12V? Chances are your motor is recharging the battery but its just your battery is almost dead.

Re: dead batteries

i had the same issue with my 800 cca battery. i went to a 1000mca and never had another issue. be sure to keep an eye on the water level even though it's maint. free you still need to check the water levels.

Re: dead batteries

Do you have a lot of axillary items running?
(fishfinder - stereo - navigatioanal aids - etc)
They can cause a lot of drain on the charging system and the battery
