    Thatís utter bullshit from whoever told you that

    It's in the manual, at least it is for the '17s.

    It says the possible voltage differential (start bank/house bank) can damage sensitive electronics like the Vision screen so 1+2 should only be used in emergency situations.

    Yet another reason to ditch that switch then.

    Although I donít see how running two batteries in parallel can somehow cause voltage differences.

    And i agree with you.. Parallel should be putting out roughly the same output. But yah, dealer said its not good for the electronics on the boat.

    I use 1+2 to start my boat every time, I use 1+2 while surfing, wake boarding, etc. When we get to party cove, I reach down and switch the perko to battery 2 and run stereo, blow up rafts or the island for the kids. When we get ready to leave I use my airhead pump that connects to the battery (battery #2) to deflate the island and raft, switch the perko back to 1+2 start up and away we go.

    Never had any issues with electronics or screens...I am calling BS on that as well.

    This takes all the guess work and switching out of the equation and only costs $45!

    Those are nice, I've used them in the past. If you keep the switch on 1+2 there can't be a voltage difference. I think the manual is trying to cover people running one battery dead then combining them.

    Is there a shut off switch for the battery isolator? To stop any parasitic drain while boat is not in use?

    Yes. That I could see as an issue. If battery 1 is dead and battery 2 is 12V then you end up with 6V. Problem is how would you ever get the dead battery recharged without using a separate charger then?

    With the battery doctor you donít need a perko switch at all!

    Yes! On My Craz it is under the observer seat. But that may only be that way because I got my boat with only one battery, from the dealer.

    I ALWAYS turn the battery off when Iím on my lift as I found that the screen drains the battery when the boat is off. If you look closely at the screen when the boat is of (in a dark place) you can ever so faintly see it is on!
