All of this stuff was in the July 1973 Propeller. The blip on Bob Wanamaker's Flying Quarter was from Ann Strangs column. She didn't mention the Rotary, the the Flying Quarter results show Evinrude RC, so I presume that is a rotary.

Wayne (Master Oil Racing Team), your posts are exceptional, your tenacity in bringing them to us, inspiring, and your love of taking the time to share, to collect, to photograph, to collate, to explain & most importantly (I say again) to share this wonderful sport with us is appreciated more than I can say. I also include, Sam Cullis (Mark75H) & Ron Hill for their time & passion together with many many others. Thank you for this place.
Ken
Thanks Ken, but you have been an inspiration to me in your drive to put togther a quality all-things-OMC website. I feel fortunate to have raced in a time when boat advancements and rapid motor developements brought speeds up very quickly and when there were still many competitors and race sites. The Wankel was one of the most unique happenings of those days. I was glad to have seen what small part I did. For those who were not able to experience it, I applaud your efforts to make this thread the premier place to come to find out about the OMC Rotary Combustion engines.

Many thanks to John Sheldon aka 'ROTARY JOHN' on BRF for providing the above literature.
The first engines were made from 2-2rotor water cooled engines. They had many snowmobile parts, but also many new parts. Engines were torn down after each race/outing/test and rebuilt with some used parts and some new parts, depending on there condition at teardown
Mostly new. rotors were seldom replaced, but bearings & seals generally got replaced every teardown. Cranks only had a design life of 25 hrs, so they got replaced rater regularly, but not always.
Yes, because the huge center section used on the 2 rotor and first race engines were replaces by much smaller parts with bearings and the engine had 3 center hsgs rather than 2 and 2 additional end hsgs.
I would think the dedicated 4 rotor motors also benefited from being charge cooled rather than water cooled as the early snowmobile converted motors were.
So as a guess the total weight of the original motors may have been 260 or so and the later motors ... 220 to 240, just as a guess?
This is Ann Strang,s column from Propellor October 1973. In regard to Lynn having to fly back home because of Mike's accident, Bill called my Dad from Provo about Mike's accident. He drove a 4 X 4 or something like that off a small cliff or some bluff if I remember right. I was only around Mike a few times, but I recall him as a very rambunctious kid, and as most are at that age....very indestructable.
These next two items come from the September 1973 issue of Motorsport. The tidbit about Gene Rhea and John Strader were in the Things-I've-Learned-by-Hanging-Around-Strange-People column of editor Harry Echols. I posted it on another thread a little over a month or so ago, but to me its better to repost here than provide a link. However, it might be good if someone could link to that other thread for all the other posts that came up.
Thanks Wayne. We heard the cry babies from Mercury screaming very loud back during this juncture in time, everything from what is written here to the questioning of displacement. I have not read the book John suggested regarding Wankel displacement, but in that case, I can see why one might consider a rotary to be whatever the chamber size is times 3.
It would be really fun to see these engines on a course today with the newer boats.
