prop my boat

[bass0825]

Just put a 2002 50hp 2 stroke on my 16' fisher alum bass boat. I put a alum. 10 1/8 x 15 pitch and I'm not getting much bow lift .

The prop sounds about right!

Whats your trim set to? If it's power trim, you need to trim up till the motors cavitation plate is level with the bottom. If it's manual trim, pull out the pin, & raise the motor to match this. This is a starting point, if you need to, you can then trim up till your prop starts to slip, then go down a little, till it grabs, usually this is your best running position to keep the bow up.

Re: prop my boat

You really did not supply enough information--engine brand, boat weight, engine RPM at full throttle ETC.

Does the hull not get on plane and plow through the water? if so, you are simply underpowered for your application or overpropped for the load.

Now, if the hull is plowing while on plane, cupping the prop to a specific cup will make it a bow lifting prop but that may not necessarily solve your problem.

However, without knowing more, all this is just guessing.

That hull design(mod V, maybe 6 degrees dead rise) won't produce any real bow rise once planed off. It actually has more dead rise forward than at the stern for a smoother ride. It's designed to run pretty flat.

It's the nature of the beast. If you put a prop on there with more bite, it'll just start to porpoise when you trim it past a certain point, but there won't be any real bow rise like you see with a pad hull.

If you put a 70 on there, it'd ride the same way.
