1985 150HP Evenrude -battery drain on startup

[wt4233]

I purchased a new battery for this season a couple of days ago. I have not had my boat on the water since last Oct. Last Oct my batteries were going dead fast and then a few days later after a full charge they would not crank the engine but just a few seconds. I was wondering if I ned a new starter that will not pull the battery down so fast. No other electrical components are on.

waynet,<br /><br />Is your engine recharging the batteries.<br /><br />If you hook a voltmeter across the battery terminals, it will read about 12 volts without the engine running and 13.5V plus with it running.<br /><br />If not, you're not charging.

It does not have an alternator & these are brand new batteries.

Howdy, WayneT.<br /><br />Your starter is not the trouble. <br /><br />You have an electrical drain somewhere in your boat wiring that is draining the battery.<br /><br />Good luck.

wayne,<br /><br />How do you figure that the engine doesn't have an alternator? I'm not aware of any 115's of that vintage that didn't.
