Prop for Beta 16 on Islander Bahama 30

Just wanted to throw in my two cents for what it's worth.

A couple of years ago I repowered my IB30 with a Beta 16 using recommendations from the folks at Beta US. The prop is 13" x 8" three bladed model with a 50% blade area ratio from Michigan Wheel (Model DJ355). When I installed this prop it appeared much larger than the 3 bladed model I removed from the Volvo MD7A.

I believe that the prop may be slightly oversized as I have been unable to make full RPM on my Beta (3600 RPM)...Can only get to about 3100 RPM. However, at this RPM I am making hull speed. This also may be due to the throttle cable needing adjusting and I plan to investigate this further.
