I just built a Goldberg Seahawk seaplane. I took it out for it's maiden test flight and the OS Max .035 (about 20 years old but runs perfect) and it wouldn't get the floats up on the step and therefore it would not take off. I want to keep the weight down. I am considering putting a new OS .032 SX on it. My question is whether or not the new OS .023SX will significantly increase the power without adding weight. The .032 is very close in weight to the .035 engine that is on the plane.
