running in one big circle Dave :roll:

glad the wheel finally fits. what a pita to get something that works. i know the original prop they told me would be right for mine also was over the top end rpms too i think the light weight of our cold molded hull throws their calcs off some.

Dave,
What is the final wheel size, is it a stock prop from their inventory or did they tweek one of the sizes?
Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! :roll:

I tend to agree with you Billy. Fully loaded I am at only 2600#. I suspect the ski rigs this engine is used in weigh in over 4000#. That is significant.

Ken - it is the tweeked 1492. Upped the cup from .105 to .130. That was all it took to get the RPM's down. The singing was stopped by squaring up the trailing edge of the blade. The porpoising was stopped by a 6" long wedge only 1/8" thick.

Unbelievable that such tiny adjustments was all it needed to lock down performance.

I have been above 60 before but with high RPM's. This felt right and the engine was not screaming at me. But I was by myself with a full tank in smooth water in cove. It was SUWEEETTTT!!!

Dave,
you originally needed to knock off 800rpm correct?
and you propped from a .105 to a .130 cup correct?

I was trying to get from 5800 to about 5000. This increase in cup reduced it 500RPM to 5300. I can live it that

IDLE TIME!!!!! Who is the heck has idle time? The shop is the therapy from the 5 (yes FIVE) frigging companies that drive me bananas in this frigging economy with friggin high gas prices and friggin yellow back leaders causing all types of friggin nonsense for us guys just trying to make a friggin living. Criminy where's my shop - I need to breathe some sawdust in a hurry to calm down!!! :lol:

Did you notice that is about a 0% slip on that wheel?

Ken - What chart are you looking at? The calculation chart I have still shows some slippage ( a little over 5%) with this wheel. Looking at it from that point of view that is quite unreal. OK, I am leaving this puppy alone.

Well, I took Midnight out for a 70 mile run today. The water was choppy and I had extra weight with passengers. Top speed was 57mph today at 5200 rpm

I don't know what Bill Weeks did to this prop but dang, it is suweeeettttttt. Smooth as silk.


And then we almost had a castastrophe at the ramp. Friggin boat dock owners had stretched their anchor cable across the ramp. It was about 2' underwater. My trailer caught it across the back corner. My wife noted the cable as she was coming onto the trailer, but fortunately she had already killed the engine and stopped the prop. :shock: :shock: I was one TICKED OFF person. I got off with only some paint damage on the trailer. It is stuff like this that would drive a man to kill someone. :twisted:
