Ride on 18's with brackets?

[Keyscruz]

Hey Dog, My 1978 18 has an aluminum bracket with a 22 inch set back and a large flotation chamber. The transom is partially enclosed. It has a 150 etec. Bushwacker's analysis is absolutely correct. At the time I put this boat together the choice for a 4 cyl. 2 stroke was limited so I went with etec 150 which is a bit heavy for the 18. If I were to do it over again I would go with a Hermco bracket with the least amount of set back that would allow the engine to tilt so it is out of the water and I would put an etec 130 on it. Having said all of that I do LOVE the boat, the bracket layout, the speed, the rough water ability. I have some pictures but can't seem to find the time to figure out how to post them.
