I never thought a simple thing like adding a blade to the prop would make such a difference, but believe me, it does. Took my toon to Cat this morning. Had the logs acid washed and Cat installed the four blade prop I had ordered at his suggestion. Same pitch, a quarter inch smaller in diameter, but oh, my goodness what a difference it made.

Proof in the pudding: On the way over to Blue Creek my boat was slogging along at 22mph, occasionally 23 (measured using GPS in my phone). On the way back to our cabin I cruised at 29, and with a little trim adjusting ran quite a while at 31. The engine sounded like it was telling me "Ah, now this is better!".

Don't have a scientific measurement, but efficiency is way up, only using half to two thirds the amount of fuel for the trip back to Parker Creek.

Obviously some of the increase in speed and efficiency is due to cleaning the gunk off the logs, but allowing a 3 mph increase for the cleaning still leaves 6 mph due to the four bladed prop. Not too shabby for a hundred and fifty bucks. Heck, I'll recover that in better fuel efficiency before memorial Day.

BTW, Cat was also telling me about this gizmo that you can hook to your boat that will give him umpteen different readings on your boat's operation and allow him to pinpoint your problem, even when he is down on the Gulf screwing off.

So, Mariah is one, and Hodja is another four blade prop believer. Thanks, Cat!
