Re: plaining problems

If it revs up when you try to trim up you could be too high your correct. Generally the anti ventilation plate, which is the flat plate just above the prop on the engine, should be very close to in line with the bottom of the stern. Some boats will work with it above some will not. A picture from the side with your engine down would help to judge this. There are props which help with lift and may be useful if nothing else works. First check to see that you are not carring a load of water, weight will keep you from getting up on plane. Next make sure the hull is clean, a polish and coat of wax most likely won't hurt anything but your elbows. Happy boating.

Re: plaining problems

the AV plate should be 1-2 inches above the keel. this may be part of your steering problem also.
