No, I already had the heavier .032 bottom corners and .025 upper ones, and a
few other mods to strengthen the front fuselage. The fuselage is also cut
back 3 inches.
This O-360 is at most 10 pounds heavier that my old O-320. While the crank
and prop may be heavier, these new ECI cylinders are actually 5 pounds
lighter. And my new cowl is about 5 pounds lighter than the old one. So net
weight difference with the new engine was negligible in my case.
Yes, on my first flight, I noticed I had to use more right rudder on
take-off and climb, but cruise is the same. I also have my vertical fin
offset by .75 inches as per the original instructions, so that probably
helps in my case, too.
So in flight, and on the water, this plane behaves exactly as before except
better performance. The VGs also work better with this engine for water
take-offs.
Please note that I am not advocating using this engine in the Rebel for
normal amphib operations. My old O-320 worked very well. But my flying is
mostly in the mountains, and I like going into smaller high alpine lakes,
where you need more power, but your engine produces far less than its rated
HP.
For normal cruise, I just throttle back and enjoy my better fuel efficiency
as I did on this last trip.
Walter

Walter: Did you make structural modifications to your
Rebel fuselage befor you installed the 180 hp engine?
Also with the larger engine does the aircraft have any yaw
tendance?
