Guys : The Michigan Wheel props that I have seen have a much wider (cord) blade than the Catalina OEM Sailor Props!!  I've posted this MANY times.

A few thoughts

My throttle controls 'slip back' at higher rpms.

Up to ~2300 rpm, the throttle lever stays where I put it.
It will rev higher, but will slip back to ~2300-2400 with the throttle lever physically moving back over a few seconds.

Would love some suggestions where and what adjustments/inspections I should make to resolve this.
Is it the cable itself, the lever at the binnacle, or some other adjustment?

Edit: Seems it can be fixed either way as per KWKloeber's link below. Either tighten the friction screw for the lever in the binnacle or add a 1/4" clamp to the throttle cable in the engine-bay to increase friction. One requires compass removal, the other is easier to adjust in the future. And when I went to install a clamp on the throttle cable, I discovered there was one in place already. I tightened it a smidge, and now my throttle holds all the way to WOT.

She'll make .5 past 6 knots. She may not look like much, but she's got it where it counts. (I've added some special modifications myself.)

Common problem has been discussed here before.  Try a search.  My temp fix is a rubber band wrapped around the guard tube and back to the lever.  Then when I have time, take the compass off and tighten the bolt to add friction to the lever.  There have been other fixes discussed.
