Why do you have a 75# outboard on a Monty 17? My 2 hp pushes my boat easily at 4kts, 1/2 throttle. Its plenty of motor. It weighs 27# and keeps the aft of the boat light and out or the water. The motor stays in the garage till I leave on a trip. When leaving I clamp it to the transom where it stays for the duration. To tow, I rotate the motor to the"reverse" position so it can't move up. I launch many times in a season and not having to deal with the motor each time saves me a lot of trouble. I also changed to the Rudder Craft rudder with the extendable Mast support for the same reason. When I arrive at the marina the rudder is in place and I am also ready to raise my mast. Lately I have been rigging and unrigging after I launch. I find it safer to do so when the deck is not so high from the parking lot. I also like no fuel tank in the cockpit. Nothing underfoot. On a sail in the delta there was much water hyacinth tangling up on motors. Because my motor is mounted directly to to transom, the prop is closer and within reach to clear of obstructions.
