Lund Explorer 1650 w/50 Yahama 4 Stroke

[Guest]

I have owned this great boat for about 2 years and am wondering what sort of props others are running. The boat came with a 14-inch (could not get RPM’s high enough with a 14”) pitch on it and I ended up testing different props until I landed with an SS 12” prop. I can get it up to 32 MPH (5900 RPM) but am having a tough of a time with cavatation (the prop does not give me a lot of bow lift either). At any speed if I bump the tiller it will cavatate. I think it might be mounted to high. Does anyone else have any similar problems or use better props?

Lower the motor and go back to your original prop. There's a reason that your motor came with that prop: good all around performance. Sounds like you're not getting it and may be a victim of bad set-up.

I run the same boat with a yamaha 2 stroke. Your max operating range for that motor is 6000 rpm,were you getting that with the original prop when properly trimmed out? Like bryce said you may have to lower the motor. If your not getting the max operating range with the old prop you may have to add a hydrofoil or go with a stainless prop. Also check to make sure your boat weight is evenly distributed..

D-man the original prop (14") could only turn 5000 rpm the SS 12" can turn around 5900-6000. I feel I have the right prop but it sounds like the Dealer mounted the engine it to high. What does a hydro-foil or a planer do to boat?

[Guest]

The hydro will keep the bow down resulting in a quicker plane and will also keep the boat from cativating. But i would lower the motor first and see if that solves the problem. You have to drill holes on the lower unit of the motor to mount the hydro.
