I took my wife out today for her first ride on our V-22 Revenge. I experienced the same sensations I have had the other couple times I have had it out...Namely that the boat feels very bow heavy. I noticed today that the engine needs to be raised a hole or two. But then it occured to that I am home, that possibly the tilt trim needed to be run out a bit to raise the bow some while running. Does this make sense? I was running 20-25 mph tach not working , using 10-12 gallons per hour. BTW it was absolutely beautiful on Monterey Bay today.....Dave

It may well be that you need to trim the motor out more. If the motor was trimmed all the way in it will definitely plow and slow you down. I would think one of the first things you would do during sea trials to run the motor through it full range of trim just to see what happens and learn how it feels. That trim range is there for a reason. It's meant to be used.

If the motor is all the way down you might benefit from raising it one hole but probably not two. I believe the factory recommendation for the classic 22 hull is motor on it's lowest hole. I have seen 22's with 200/225's mounted one hole up and I have seen motors that were mounted one hole up and then subsequently lowered back down.

I would think you are more concerned with maintaining grip in the ocean swell rather that maximizing the top speed in a flat water run.

Either way, the vertical mounting position of the motor would not have anything to do with a plowing sensation.

Tom is right about the trim.

However, regarding the mounting height of your motor, I have an Outrage 22 with a 225 Evinrude that is as happy as if it was in its right mind, *2* holes up. The difference is, and would be with your rig too, in the prop. A standard un-cupped prop would probably not support an installation 2 holes up, and you'd be getting slippage and ventilation. If you don't have a cupped prop, youy probably ought to think about it anyway; it will also support a greater ability to trim your motor out without ventilation.

Thanks for the replies guys....Tom, you are right about it being there to use, however I have never used one before and quite frankly forgot it was there... hence the "I might be an idiot" ;')...Dave
