Sounds like something @swatski can help with.

May want to post with "[USERGROUP=9]@HELP[/USERGROUP]" in the forum to get quick help!

Do you have a "combine" switch?
Yes, there is no chassis to the ground in a boat so need to connect directly to the terminals. If the connections are firm should be fine.

If I understand you correctly, the answer is yes.

First check for fumes. Open the engine compartment and sniff/blow etc....

THEN, connect the cables as you describe. Not sure why the two batteries would be both dead---you must have a strong battery drain, or its been a long time since you used the boat.

If you are talking about combining the batteries, you should have a combine switch in a two battery set up-unless the 2nd battery was never installed properly and its just sitting there????

I think maybe he has a 2nd battery (not combined into a 2 battery system) and wants to make sure he follows the correct procedure.

@Motivation007 I believe the best is to connect the terminals to the dead battery terminal (not each other!) and to give it a bit of a wait. Unless of course you can just swap the batteries...

Basically:

• correctly connect the batteries terminals together
• wait several minutes for the battery to charge (equilibrate a little bit)
• turn the boat key, and see if the engine starts
• disconnect the leads so the battery can charge normally
