Can two batteries be run on a 17-foot Boston Whaler boat? Is a battery switch used with them?

If you intend to hookup two batteries together the best way is with a two-battery switch.

Of course you can. Hell, you can put 50 batteries in a 17 if you want to! My opinion? Off/1/Both/2 switch and a battery isolator or the Blue Seas ACR, like Alfred is doing.

I wouldn't put 50 batteries in a 17, unless they were double A's or triple A's.
That extra weight will play havoc with performance and you will have no space for coolers and fishing tackle etc.
Just my 2cents.

Maybe a "hybrid" Whaler?

My 18 ft. Outrage came (used) with two batteries and an A, B, Both or Off switch, all in the console. I have been running it that way, but I just got a new battery, and I think I will run with one. It saves some weight and space in the console. The new battery is also sealed which should be better for the other items stored in the console. I will keep the switch though. I have had the solenoid stick in the on position. Its nice to have a master switch to shut everything down. Dave

I ran a pair of group 27 batteries in my '79 Montauk, rigged with the typical Guest 1-2-Both-Off switch. No problems with performance, trim or any other imagined problems. They tucked neatly out of the way in the stern of the boat, and were usually hidden by the removable bench seat installed in the back of the boat. The seat made a great casting platform in calmer water, and was used to carry a 72 quart cooler and other gear when fishing.

The batteries provided extra reliability for a 17 foot boat used for fishing offshore in the Pacific. sitebuilderpictures/batteries.jpg sitebuilderpictures/bench.jpg

In my '79 Montauk/Honda 90 I had dual batteries inside the console with the Perko switch mounted up as high as possible inside the console. I liked the weight more forward and the switch higher up above the deck.

I alternated the use of #1 and #2 each time out and liked the peace of mind.
