Re: power tilt
Welcome to iboats.
Absolutely, the boat will handle much better and your performance will improve across the board.
As it is now your engine is trimmed correctly for one set of conditions with trim you can match any condition.
Look here in the iboats store at a CMC TT, you should be able to get it on in less than 1 hour and the ywork right out of the box.
Had mine on an Evinrude 50 for 4 years and it is worth every dime.
Skip the trim gauge though, it is extra and you will never even look at after the first couple times out.
