here's the info on boat. it's a '86 winner tournament 2000. 20 feet 1200 lbs. i was original onwer for 16 years and sold it when i got burned out on fishing. ( i know,insanity). my wife suprised me by finding it last year and bringing it home.in the years since it was gone it had been abused badly. all the electronics i had on it were gone,the tiller style 40 lb thrust bow mount Motorguide TM replaced with 70lb Minn Kota foot steer. not happy at all with foot control and want to go back to tiller style. i tournament fish team tourneys at club level with my wife for fun not money and have no need for 70 lbs of thrust and putting out a wake. researched a lot this afternoon and have eliminated wireless,varimax,and digital. my biggest question now is i don't see anything in the 55 lb range that's not 12 volt.question is, do they run these with two batteries in parallel? last TM i had used 12/24 so this is all new to me or do i need to get a 70 lb 24 volt model and just run at the lowest speeds?
