I agree...need pictures....what kind of prop are you running?? What pitch?? Do you know? Should show on the prop somewhere. That can have alot to do with it. Does it sound like its whinding up?? Or does it sound like its lugging?? Should easily get you and your boat and cargo on plane. Is it a long or short shaft??
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
