Regarding jumpstarting- here's my vote: <u>DON'T</u>.


A much better solution is to plan ahead- start with an APPROPRIATE cranking battery (see the following post):

Begin each outing with your batteries FULLY CHARGED.

With today's electronics, it's likely you have SOME electronic device in your boat that indicates VOLTAGE. Make a mental note to monitor voltage occassionally- if it falls below 11.8V, start the engine and allow it to run at least 5 minutes.

-------------------------------------------------

Now- all that being said, if the WORST happens when you're on the water, we BOTH know you're going to do what you have to in order to get back in.

IF you choose to jump start- connect ONE trolling battery to the CRANKING BATTERY (positive to positive, negative to negative). ONLY ONE battery from the trolling bank should be connected.

Check your connections THREE TIMES before connecting the last wire end. Any error in jump starting connections can result in SUBSTANTIAL electrical system damage- and potentially leave you "dead in the water" (the very thing you were trying to resolve).
