DF300 23 Sceptre

Hey Danny,

Your pics of the AV plate under way look about like mine! Hard to see a white plate under all that white spray! Need to put some black electrical tape on top of it to see it until you get it high enough! I've also attached a pic of the height measurement setup.

Been thinking about comments from Ken and others, and I believe it's hard to conclude anything about prop selection and potential motor issues till you get that AV plate up out of solid water. The propeller hp vs. rpm curves I've seen in Dave Gerr's propeller book look fairly linear, so I would think that you should be able to spin the same prop as a 250 Zuke 10% faster if your motor is really putting out 20% more hp!

Sounds like Don has the motor height dialed in pretty well, although the setback of his jack plate should allow him to run a bit higher than if it was mounted on transom. With 30" of setback, I'm slightly over 4" and it's STILL not high enough! Denny
