Wellcraft Airslot 165 with a Johnson 120hp outboard

[saxrulez]

The current propeller on the boat is a 13x19 and is pretty dinged up. With that said, it currently seems to run and accelerate pretty well but I don't have a tachometer yet! I'm going to install a tach in the very near future, but I also wanted to replace the prop this week since its so dinged up. Does this size propeller seem reasonable? I'm satisfied with the performance, just wanted to make sure it wasn't blatantly wrong before I replace it with the same size prop.

Short video of it with the current setup accelerating.

I got it to 42mph on my GPS with the current prop as well.

Yup, that's in the ball park.

I always wanted one of those..Before you go do the prop deal you might want to explore the notion of engine height,,is it to high or to low.
That is the where the cav plate is running is it below the hull if so how much...equal to the hull or above it.. A quick trip the outboad forums to find where that motor should run at (rpm peak)

Out boards have a lot of flexability...a few inches here or there and then the right prop can make a huge difference...as much as 5-10 mph..That hull is pretty unique..A good overall lifter in a four blade would be my first choice..
