What prop should I try if I want to increase stern-lift? Seems like everyone likes props that increase bow-lift but my boat seems to prefer some stern-lift for top mph.....I am running a Michigan Ballistic which works better at mid-top end. The Mirage planes and accellerates better to about 3500 rpm's....

If yours has a hook like mine, it would seem it would like bow lift more since the hook is keeping the bow down. I just sent a check for a 21 cleaver to try on mine. I have a 23 cleaver on it now.

Wow; this could be a long talk. In general "cleaver" props develope the most stern lift. Merc. Mirage will give you the most Bow lift. However, there is NO prop that will compensate for a hull problem. BEFORE YOU BUY MORE PROPS, CHECK OUT YOUR HULL!!! Been there-done that!! --- Jer

Now, I'm going to try to make this easy. Just like you can't tune out bad compression on #7 cyl. by adjusting the carb, you can't fix a hull problem by changing props. --- Jer

Well Jp me and "Cuda" have the same hulls. Our Formula's have a "hook" built in. A dead cylinder is probally not a good comparison. I think it would be more like a how some race cars have more down-force than outhers. The built in "hook" provides a more stable ride than some outhers but at the expense of top-end. Wouldn't a hook cause the stern to squat. I would think that "bow-lift" is worthless if you can't get the ass-end loose. Hell isn't it kind of like a stepped hull vs. a non-stepped hull? A cat vs. a deep "v"?

I'm going with the cleaver because I have been told it will minimize the heeling to port. I haven't really tried out the 23 cleaver that is on there, but when I took it out with 4 people and a full tank, it was a ***** getting on a plane. Now that I have another boat coming, I can afford some down time on the 20, so I might try to take the hook out of it myself. I know I can float a wavy floor out enough that you can sit a marble anywhere on it and it won't roll.

A hook in the hull will cause stern lift. You need a prop with bow lift to compensate for the hook. A 4 blade prop will generally provide more stern lift than a 3 blade. Sounds like you need something like a 3 blade Mirage+. Also, more cup in the prop will cause stern lift, too. This has been my experience.

Cuda, you don't have tabs to compensate for "Heeling"??. Man, we are going to start from the very beginning here. But I can tell you this: When it is all set up right , at WOT the tabs are UP and the boat "HANGS" in the air. About 2 sq. ft. of the a$$ wetted. I cuold send some pics if I need to prove this. --- Jer

Just my 2 cents guys.>> I repowered a 208 Baja Islander with a 502 (500 hp) and had some serious handling problems. I admit some of the problems are in the hull but>>> I tried the whole gambit of Mercury props, Mirage, Vengenance,Bravo I, Trophy, and Lazer II. The prop that worked the best for me was the Laser II. I know it's a prop mainly designed for outboard bass boats but if you want to get the bow up you need a high rake prop to push the stern down ,small diameter 3 blade worked better than 4 blade, smaller diameter worked better than large. If you can get your mitts on one try it Again just my 2 cents

I misread the post i thought you were speaking of bow lift.
