Don't overlook this engine. It weighs 42.4 ounces and the ignition advances the timing for better starts and more power at full throttle. I don't believe the FPE engines have ignition timing advance-a big disadvantage in my opinion.

The 3W-24 is equal in power to the Zenoah G38. It'll turn an 18x10 or 20x8 prop with no problem once broken in.
