I recently bought an 89' prostar 190 with a 351, a 1.5:1 trans, and a LH 14x14 prop with a ding in it. My problem is I am only getting 36 mph at 5400 rpm WOT. Am I correct in thinking this is a prop issue? I bought the boat in Colorado and I live in nebraska so I am at a much lower altitude but to make 5400 rpm doesn't that mean that I am getting all my engine will give me?

I would suggest a 14 X 18 LC 1 1/8" FORCE 4-blade.

I want to get around 43 mph for barefooting is it realistic to think that a prop change can make that happen?

I've put that prop on both of the power slots that I've owned and they are great. I thought all of the power slots came with a 14 X 18? With a 14 X 14 prop on your boat your motor is maxed out on RPMS because of the smaller prop. The 14 X 18 will increase your top end speed and may drop the RPMS a little (I've never checked mine). The Force 4-blade has a great hole shot too.

I think the 14 X 18 will be a good place to start.
