I am running a GT 11 pitch 3 blade but was hoping for a little more top end. What is everyone's experience with the two blade? I carry a lot of heavy loads as a rule so it has to be able to push a load not just a light boat

I have a big heavy 1852 and had a 3blade 10p a d it didn't carry a load very well. I swapped to the gt 10p 2blade and it was 1.5mph faster with a light load and quiet a bit faster with 4 adults in it. It went through mud and vegetation better and reversed better. Only negative is it vibrates quiet a bit more. I have a 2015 carb motor stock besides k&n air and slight tinkering with carb. But if you do a search, some like the 3blade better. I would like to try a mb bb on it.

The BB on mine was a little faster light but slower with a heavy load. Of course, we are talking a couple miles per hour in any direction so at times it seems fruitless lol

Like someone said on another post, there is no 1 magic prop made "yet" that is the best for all applications. Power Tech is currently making a 4blade 9in prop for the guys who hunt the restricted marsh areas. 2 of the blades have a 9in diameter and the other 2 have only a 5in diameter, giving it the same surface area as a 12in 2blade prop making it superior to any prop previously made.They have the balancing problem almost solved and it may even be out this year... Cough, cough, bullshit, cough. Lol
