I'm trying to help my father in law prop his pontoon boat.
It's a 2004 model J90SLSRM, 2 stroke.
He had a beat up OEM 391668 and said he would only get 5200 RPMS.
I have him a MI wheel 012047, 14x11, and he now turns 6200 RPMS.
Ok here is where something is a little off. The pitch and diamter I have for the OEM prop is 11 x 13. I think maybe the number is worn, and it is supposed to read 14 x 13.
Also guess the OEM prop is a cupped prop, as he claimed the OEM it would come out of the hole a lot nicer.
He want a new OEM prop.
BRP has the "hydrus" line which is supposed to be designed for pontoon boats.
My choices are 13 7/8 x 9,11,or 13.
I have no clue what the max RPM or operation range on this motor is. I don't have a single manual that covers this manual. If anyone knows it is greatly appreciated.
