OMC 727 race motor

[Powerabout]

Does anyone have any photos of the V6 looper race motor that came out after the CCC but before the V8?
Was it called a 727 internally at OMC?
Was it a one off or did it share this from the 90degree loopers?
Any still around?
Thanks

The 727 was before the triple C. It was a 2 liter (122 cubes) and it was not based on any production design. These were mounted on The V4 Strangler mid and gearcase. A small number of these were made for factory drivers only. Jim Nerstrom (NERSTROM on this site) would be the guy to ask about any technical details.
I doubt that any still exist but its possible.

Ok Thanks, ..2 MOD 50's joined at the crank??

how about the V6 engine Cees was working on.
What was that based on or was that a one off as well?

You will see that motor decaled as the Super Strangler V-6 and Stinger GP V-6. What I heard was OMC prototype protocol called for 5 prototype units of any prototype motor. One would be used in destructive analysis ... run it until it breaks ... and the other 4 would be tested otherwise. This sometimes let a pair of motors be decaled as Evinrudes and a pair as Johnsons.

I doubt the 727 was a pair of Mod50's Mod50's are 50 ci, 820cc; double would have been 100 ci or 1640cc

Well what I remember is the 727 came after the CCC, the 727 was a 6 cyl looper version of the V8. It was not a 90 degree.

The V6 Cees was working on was the SST3000 which was based on the production powerhead, and of course there were the 2.0L V6's but I think most of them were run overseas against the Merc 2.0L.

I did hear that the 727 was an incredible 3 litre V6 looper race motor which was significantly superior to the subsequent looper released by the production group but for reasons only known to the heirachy it was canned.

What I want to know is what was the F1X aka W9 motor which would have been a "fix" for the Mercury competition.

Well what I remember is the 727 came after the CCC, the 727 was a 6 cyl looper version of the V8. It was not a 90 degree.

The numbers don't add up for that scenario. The first V8 was 3.5, adding 30% to a 2 liter only gives 2.6, pretty far off from 3.5.

Second, the 727 was raced in 1974 along side the V-4 Super Strangler & Stinger GP's, the CCC raced from 76 to 1980.

Perhaps some input from Mssrs Nerstrom and Hauenstien could clear this up. My notes say the 727 is a Hauenstien supervised motor, and the V-8 a Leek supervised motor; 2 different teams.
