I bought a CMC several months ago for a 70HP. I love it and was worth every penny. Easy to install. No more worrying about falling off the back or having to manhandle the motor at the ramp. Boat runs a little faster and a lot dryer than it ever has. Go to BPS and add another switch so you have one at the back and one at the console. I might even add me another one to the bow for when I get in shallow and need the motor lifted.
It is pretty heavy duty and adds some weight to the transom. My boat sits a little lower in the water with it.
