About to launch new (used) boat tomorow.<br />Turned key on tonight and noticed battery reading 11.8. 24 series battery. Yamaha 200 engine.<br />IS that too low to turn over the engine?

Re: Battery reads 11.8

The best way to know is to try starting the engine on muffs before you launch your boat. It takes more than a voltage test to say whether a battery is good or not - the guage could be wrong too.<br /><br />Don't wait until you launch it to find out - I did that once and it's no fun if your motor won't start.

Hi capecliff<br /><br />Battery voltage tells a story, but you must measure it at the battery with a accurate meter. Atleast do it once to check the accuracy of your onboard voltmeter.<br /><br />12 V = near dead<br />12.5 V = approx 1/2 charged<br />12.7 V or greater = fully charged<br /><br />To be accurate with this, the battery musn't have been charged within an hour or two.<br /><br />11.8V is way too low. Not only will it damage starting components, but it will be very hard on the charging system when running. CHARGE before operating! :)
