Well with the powertech SCE4 I'm turning about 5200 RPM max with the jackplate up and trim tabs all the way up. Getting about 35 mph. At 4300 RPM I was getting 32 mph which is ok, but I was hoping top end to push a bit more. I'm going to try there recommendation and I may try to see how swinging a 3 blade with high pitch works out.
Unfortunately I think my engine and bracket are sitting a little low in the water, I am pretty much running with my jack plate up all the way. Water comes over the bracket with ease even with nobody standing in the back. The counter bouyancy of the bracket does seem to offset it from going down too much further though when people do stand back there which is good. However it's tightly sealed no water inside the bracket, just having to be careful coming off plane not to swamp the engine, as well as when running as if it's not trimmed right water seems to want to shoot up at the cowling.
