i am running the yamaha 250 hpdi on my 06 cougar with a 27m yamaha prop. right now the hole shot is pretty good and at wot i am turning 5800 rpms and 76.8 mph
by the gps with 2 people and full load of gas and equipment. numbers are fine but i don't like the lift i am getting feels like i am running really flat.
was wondering what differance the 27 t yamaha prop would make in my numbers and would i have more lift ? i know the t has more blade area and i think it is
recomended for the 225 and up engines. would the incresed blade area mean i would need to drop back to a 25 in the t series? trying to get an idea of what i
should be looking for to try out on it.thanx for any help.
