The only thing that I can think or here is that if more HP created a "heeling" problem then the hull problem (hook) really needs to be addressed. I found that with my hull when it had the hook the addition of more power only made the "plowing" worse and yes; without the use of tabs the hull wanted to lay over. Probaly not what you wanted to hear but "been there; done that", I'm sorry to say. Good luck. --- Jer

If your boat has a hook built in to it then the last thing you need is stern lift. The hook pushes the stern up and the bow down. Just like having tabs in the down position. If you try a prop with more stern lift it will make this condition worse and the boat will tend to bow steer. Look for a prop with more bow lift. Every prop is different but here are some general rules.
More blades cause more lift.
Pointed cleaver style props generally cause stern lift.
Round ear props generally cause bow lift.
The more rake the prop has the more it will lift the bow.
So you should be looking for a highly raked 3 or 4 blade round ear prop that will give you the bow lift need to overcome the hook in the hull. This will get more boat out of the water and you will go faster.
Mercury Marine and or Quicksilver used to sell a book titled "Everything You Need To Know About Propellers" or something close to that. It explains the general principles involved in prop selection.
The only way to know for sure which prop is right for the boat is to test as many as you can.

Im in the same boat with the built in hook ( in know, not funny). My problem is worse as the drive is an OMC so trying props is a pain. I have a dealer who is willing to change hubs on the new Merc props so I can try them. Does anyone know what it costs to rehub a Merc prop... in case I find one I like I can look for a deal on a used one? I remember somthing about Merc props being sold under another generic name through non-Merc dealers. The price difference was considerable. Does anyone have that info?
