the trailer is too short I cant trim the motor all the way down because it will hit the ground
Jack the trailer up and put some jack stands under the axle or blocks under the wheels. I understand what cray is saying and it does affect some boats, but most will jump out of the hole good and get on plane even if the motor is straight up and down or even trimmed out a little if they have the right pitch prop. Does your pop have a SS prop or aluminum? I have seen aluminum ones worn so bad that they would no longer perform good. But no one can advise you on prop pitch without knowing how many rpms your running wide open.Quote:

Also you may want to have some brave sole look at the lower unit when your running at close to WOT to see if your anti cavitation plate is still in the water. On my deep V the Yamaha engineers recommended using the second hole from the top instead of slapping it down flush on the transom. Just something to check.
He has it mounted on a jack plate Stan
4stroke Mercury on a 2066 F&F, The 75hp and 90hp have a min and max of 5-6000. The 60p is 5500-6000.Quote:

Get the rpm info peckerwood. Other than that we're just flailing about.
Bet you've got too much prop or a beat up prop is the overall problem. Jack too high might be another issue as well. But then, that's just me flailing.
