I Have a 15ft Fiberglass tri-hull and was wondering if there is rule as <br />to what size trolling motor I should buy. also is there a web sight that <br />explains how to rig up down riggers Thank you.....
Sounds like you do big lake fishing and need good 55 lb thrust or better. I would suggest in your case at least Minnkota 55lb 12 volt model with at least a good group 27 battery. 24 volt in your case with about 65 lb thrust would be better. I would also consider a 5-10 hp gas four cycle kicker or maybe even a 15 or 25 hp if you use planer boards. If your gonna do back trolling, make shure you use the appropriate trolling motor with splash guards on the transom.
