My problem is that the best I can do before prop blowout occurs is about 4200 RPM.
Diy pontoon lifting strakes. The Hydrofin system is a highly engineered system that can change the angle of attack to generate a lot of lift to the pontoon boat. Because lifting strakes give your boat some extra elevation they boost speeds by up to 25. Lifting strakes are blocks of metal that are welded directly onto the pontoon tubes themselves to generate lift allowing your boat to lift and glide above the water instead of tearing through it.
We have the exact same options and configurations between these boats that are nearly identical explained Evan when he first contacted PDB magazine. 1 - 20L x 25D 1LS 1RS - 650 each. Typically lifting strakes are a piece of sheet metal used to deflect water.
Hello all Jason from Louisiana. Pontoon Lifting Strakes Benefits. According to the spec sheet on the 22 GCW it weighs 2244 the same as the 22 GSI tested.
Pontoon tubes have a rounded shape and they immerse more than halfway in the water. The corneredge of the strake should be sharp not rounded. The strakes appear to go from aft of the nose cone to the stern.
The strakes welded directly onto the pontoons produce lift at the bow by displacing water allowing the boat to in essence glide above the water rather than lumber through it. Care is needed to consider the trip edge presented by lift. Adding more power to a planing hull results in increased speed.
Lifting strakes provide lift by displacing water and raising the bow above the waterline. After discussions with motor dealer and talking with Bentley reps the prop I have on it now is a 157515 pitch SS prop. The prop used in the test was a 13 14 x 14 which pushed the boat out to 272 mph at 5900 rpm.
