    I have a Mercury 25hp (4 stroke) on my Tracker Pro Team 175.

    The front rides up extremely high and I would like for it to level out. What experience do you guys have with these? Any certain brand or type you recommend over others?

    It should help but I think shifting weight or ward would help a lot more than a foil...

    Any pics of your boat?

    I have a foil on mine but I also have a 40hp 4 stroke on my 13ft boat and still have 40lbs of lead in the bow to keep it from pounding....

    How many rpms are you able to get at WOT with the 25?

    Here's a stock picture of it. Everything is the same except the engine is a little smaller.

    The 93 Starcraft I just bought had a hyrdofoil on it when I bought it. It's awesome. Makes the boat jump on plane very quickly and ride very stable. They aren't very expensive, so definitely worth a try. I usually fish with one other person and when we motor up we both sit in the back and it still planes out perfectly.

    I have a 25HP Mercury 4-stroke big-foot on a 1448 tracker Grizzly, and with any weight in the boat (ecspecially the rear) it would not plane out. I put a hydro-foil on it and it does push the back of the boat up out of the water quicker allowing it to plane out faster. But like stated above Weight distribution is key too. Also you have a lot of boat for a 25HP 4-stroke in my opinion.

    Also I bought the Attwood brand. It claims to have less drag after getting the boat on plane due to the angle of the foils.

    Does the boat have power trim? Where the motor is positioned while coming out of the hole and on plane will have alot to do with the attitude of the boat. Also the foil will help alot on hole shot then if the motor is set right it should be out of the water when on plane.

    I took it out today and I can now provide more info.

    WOT RPMs is 5000. When I rise the prop up, the angle is worse. Weight is mainly in the rear of the boat with 2 batteries and the gas tank. These are non movable due to the structure of the boat.

    The prop is stock 3 blade from Bass Pro, so I'm not sure the exact specs.

    I agree, it is a lot of boat, but in my area, that's about the limit you can have for the majority of the lakes.

    Rpms are close but a little more would be better

    Do you have a pic of the motor on the boat from the side?

    Maybe you can raise it up a hole....that would bring up te rpm and drag less....

    Those numbers are super good for a 25hp....
