Bigger boat outboard
I was wondering if anyone would know how to calculate the amount of horsepower I would need to move my boat. I have a 34' Hunter, with an inboard diesel, but I am looking to add an outboard for trolling (kicker?). I would only need to move at 3-4 kts max. But more often around 2 kts.. Right now I use my diesel, but I hat leaving it at 1500 rpm for any amount of time. Also could it be offset on the transom or would that cause steering issues? Any input is appreciated. Thanks.
