Hi all, new to the forum, new to boating. I just picked up a 1977 Orrion tri-hull 15 foot boat, and had a couple questions regarding trolling motors. First, can you steer a transom mounted trolling motor from the steering wheel, or do you have to steer it like a tiller. I know there are remote control options, but those appear a bit pricey. Second, is there some sort of formula/cheat sheet when it comes to figuring out how much thrust a particular boat needs? Or is thrust like money; you can never have enough? WHat would be too little thrust? What about a kicker opposed to a trolling motor? Sorry for so many questions, but thanks in advance for your help.
