My 25 Hp. doesn't seem to dig in when I'm under full throttle. The motor revs and when I slow down it digs in the water. Sometimes after reving it seem to also dig in. I changed props and don't seem to have the problem. They are the same kind of props. Sometimes when I turn of the motor after being at full throttle, I hear a screaching noise coming from the prop area on the prop giving me problems. Any ideas what the problem is and the fixes? thanks in advance.
