    I believe it depends on if your batteries are wired in series or parallel. Mine are wired in parallel so I still have 12 volts from positive to negative on each battery. Do you have a volt meter to check what you have from positive to negative on each battery?

    You do not have to disconnect the jumper that gives your pair of trolling batteries 24 volts if you hook a jumper from your cranking battery to ONLY ONE of either of your trolling motor batteries. Each of the batteries is still twelve volts and either of your trolling batteries can be hooked in parallel with your cranking battery to stay at twelve volts and double available cranking amps without affecting the series connection to the pair of trolling motor batteries..Just be sure to use only ONE of your trolling motor batteries jumped in parallel to your cranking battery...

    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).
