bf 50 on the back of 16 ft. I have about 5" of clearance from the foot to the road. The engine has pwr t/t but also has the manuel, 5 holes with pin through it. I was considering raising the engine, putting the pin in the second or third hole up, lowering the t/t and straping/bungee down. If transom saver is better option, which one works best--rear cross bar of trailer is 15" or so under keel. This transom saver response has been confusing.
