Default RE: Graupner Hydro Sprint

Had some time to finish her up, and went down to the lake to give it a sprint


Well, Im pleased, and a little disapointed at the same time. This motor is very powerfull......maybe too powerfull

It scoots along nicely at around 1/3 throttle, but if I go to 1/2 throttle, the nose lifts quite alot off the water, and only the front turn fin is in the water. As the fin is on the right side, the boat veers to the right all the time. If you correct slightly with some left rudder, the left pontoon contacts the water, and it turns violantly to the left......it keeps zig zaging like that. []


I might try to remove the tunfin, or add another on the opposit side....... and se what happenes, and try to move the CG a little forward.
