Prop for L'il Hustler

IHR Tech talk,

I recently purchased one of the tunnel hull 11'6" hustlers with a 4cyl classic merc50. Which for some reason is a 45 HP?

It has a manual jack plate that sets the motor back about 6" and up about 4". How do I go about making a prop choice? I was having problems getting the boat to plane until I added a hydrofoil, I know you don't like them but it does at least plane out now.

Maybe with the correct prop it wouldn't need the foil, the current prop looks like a stock aluminum, but who knows?

On that boat, the foil is almost needed just to plane off, like you say. We ran a few of these, but for now have some decent cup put in your aluminum prop. This will give you a baseline to move to a better solution. I would expect to run a 14 or 15 pitch, but you can cup your prop even if it is a 13 and it will improve a lot. Hope this moves you in the right direction.
