Rik, We've had very good luck with a 42 amp Minn Kota trolling motor on our P-15. While lighter than your Monty, I think your boat may have less overall drag due to better hull shape. If trying to limp home on a windless day, I put ours on a setting of 2-3 (of 5, 5 being full power) which moves us in excess of 2 knots with two people on board. We have a tiny U-1 AGM battery which has never let us down. I suspect it would run 2-3 hours, no problem, on these light settings. BTW, it's absolutely excellent for motorsailing in puffy light air. Also very good at the dock!

We will probably only be using her on lakes and most of them aren't all that big. I would think if I could get a range of five miles or so, out of it, that should be plenty. I might need two batteries to do this, but I don't have a problem with that as they (their weight) would reside pretty much in the middle of the boat. What was the thrust rating of the motor you were testing?? The motor I am looking at is rated, 55 lbs thrust. I have a 4 hp 2 stroke to use if I need better range or for a situation with current. But the silence of the electric is appealing for use on the lakes we would normally be sailing on. Rik
