jacmyoung,
can you do a definitive estimate (like the oxymoron irony of that statement?) of the octura 1240 mod on the k4?
i finally took your vote of confidence and did the mod to my k4.
wow, youre right...it was pretty simple.
it 'feels' to my hand to be pushing A LOT more than 1600gph...almost TWICE as much water. mind you, i did not trim the prop as much as you did and the k4 struggles like a demon to try and start up...but once it does...whoowheee!
