Merc 200hp on a 1974 Tsunami 20' - Propping Performace

Ok Guys,
Many people were asking me for Updates. Here you go... and I will continue posting my Testing. Originally had the Engine in the bottom Hole on Transom, I could Not get it High Enough.

Installed 4" Setback Jack Plate Still have 2" of adjustment on the Jack. Right Now at 1/2 Trim I can Get the AV Plate above the Green Water. (Should I raise The Jack some More so the AV is out With the Engine Tucked All the way in?)

Today I tested 19p Mirage Plus and 21P High Five.

Full Load of Fuel 50 Gallons with battery's at the Front. Keep in Mind I am Running at 3500 Feet Elevation.

GPS - 19p Mirage
3400 RPMS - 30.2 MPH
WOT - 5000 RPMS - 46.7 MPH

GPS - 21P High Five
3400 RPMS - 27 MPH
WOT - 4800 RPMS - 43.6 MPH

I am thinking that a 17p Mirage Plus will still be Too Much. I am considering the 4 Blade PowerTech in a 16p.

I am looking to get the RPMS to 5800 at My Eleveation with this Load and it should be perfect.... Anyone have some Ideas on.....

Where to set the AV Plate in Relation to TRIM and PROP Ideas?

Thank You
Robert
