that makes better sense as the changes lower the weight and have it lower down, love to find one of those later exhaust housings

Notice every pic of a rotary on a Scotti, or any other boat for that matter, the engine was always at negative trim angle. I guess if that engine was indeed making 300 hp there was no need for up trim.
Yes you are correct Mark Poole ModVP,
I think one of the reasons is/was most of the Scotti boats was designed for the V4 Super Strangler/Stinger GP at that time. When the rotary and the V6 was introduced 1973 OMC just bolted the more powerful engines to used V4 inventory boats.
Scotti did build a new V6 boat for himself and the V6 Super Strangler early 1974 and he won Bristol with that boat.
I can tell you factually, the rotaries were producing 270/275 prop shaft HP @ 7000 RPM. The HP curve was still increasing at 45 degrees at 7000. Though drivers were told not to exceed 7000, I'm sure they were aware of more power at higher revs. The biggest issue was boats. Lars was correct. The rotary was bolted on the back of the V-4 boats. Its one of the reasons the big foot 14/23 gear case was like by the drivers. Much better acceleration without giving up much if any top end. With the exception of Parker, it was how quick you got to speed, not how fast you could run.
The Law..

have you asked your friend with one to take a photo of the powerhead yet?
Sad news this morning. This is from Bob Schubert
A word to those of you who are old enough to remember the old days of tunnel boat racing.
OMC factory driver Bob Witt of Baytown Texas passed away over the weekend. Among other things Bobby won the Havasu OWC in the early 1970s. He was a marine dealer in Baytown Texas and a Johnson dealer for many years. He also was as nice a guy as you would ever meet, a great competitor and gentleman. He was a mentor to myself and many others in this region. Bobby Drove the V4's, the sixes and the rotary. He was 87 years old.
