View Full Version : What size hole for ballast bilge? Dual Battery question also

03-02-2008, 07:14 PM
About to drill 3 holes in my 05 lsv for my GG 3 bag upgrade and intergated bow sac. Anyone know the correct size hole saw i need to get? Any other tips on drilling this besides masking tape,drill in reverse at first,and clean up edges with a dremal.

Also to the guys running two batterys with a perko. I kinda confused, #1 battery will be for starting the boat #2 battery will be for all boat accesories and my amps and leds. So how do i seperate the two?
Is the 0 gauge power wire that is hooked to the battery the one that starts the boat, and the 8 gauge that goes into the breaker and then to the battery all the boats acessories?

I assume you mean the holes for the thru hull fittings? I just replaced all my with Chrome and the fittings were 3/4"...

yes that is what i mean, sorry couldnt remember what they were exactly called. You sure that is the size of the hole saw i need to buy that seems very small.

I would suggest drilling a piece of wood first and make sure thru hull fitting fits in... I just took mine back to storage or I would go measure. them.. I think there was a little bit of clearance on them but not much so maybe a small bit larger than 3/4.. you could take a piece of hose to home depot/lowes to look at saw and compre..
