Hello!
I found someone who have the same engine and boat as I do. Mercury 125HP two-stroke on a Alicraft 18.5 ft boat. Known as Alicraft Norwind 18. 500KG without engine etc. It is a small cabincruiser, got a little cabin in the front.
He had a 14 1/4 x 23P on it. I found a 14 1/4 x 23P Laser II SS prop in my hometown for a good price. But I've read that those props are only used on bassboats.
Does 14.25x23P sound to be alot of prop on a 125HP on a 18.5ft CC? The engine is a low-rpm engine as the recommended RPM is 4750-5250.
He said that he gets 37-39 GPS knots on WOT. 5000 RPM with a little bit to go on and cruising on 3000 RPM at 23-25 GPS knots. This sounds to be pretty good. Not too much noise and (for meg) good cruising speed.
So my question is, it that prop usable? I got a 13x19P alu. that I will use first, but I do not think it will work at all..
Some said that I should get a 21P if my WOT speed is around 40 knots.
