...Charlie Strang on the left. He was responsible for the 3 cylinder Evinrude Triumph that was introduced in 1968 as their first loop-charged scavenged 2 stroke, as well as their first through-hub exhaust production outboard. The gentleman on the right is Carl Kiekhaefer, who Charlie worked full-time for, prior to 1968.

That looks like a double overhead cam 4 cyl motor. It could be the one Bill Sirois entered in the Gold Coast Marathon in the Volvo class and blew away everyone. I think he finished second or third overall, then was disqualified for not being in the spirit of the rules. I think it was an Osca.
Where's Gene on this? It was early sixtys.

OMC had thru prop exhaust long before Merc. The correct phrasing would be OMC's first thru prop exhaust in modern times

To provoke Carl Kiekhaefer some more, the 1968 OMC 55 HP 3 cylinder looper had a decal on the aft end that had the patent number on it and saying OMC thru-hub exhaust.

just out of curiousity, do you know anyone on the new G2 2-stroke design team Lars?

Yes I do. Some also are on my FB page.

Two 3.3L OMC/Evinrudes at 450+HP 9600+RPM in Pro Gas finals this week. Enjoy.

Thanks Lars. Both engines are singing. Sam Baker had the MPH on the top end to take the victory. This is the first time using my new camera in my boat, so I know my editing is little crude. We will be filming every race this year in NIDBA for the TV show that's being produced on the boat racers. ��

You should get that particular patent number & look it up. It would be interesting to read the specifics of it.

No FUJIMO..every 1968 Evinrude-Johnson 55HP have the sticker and remember that pretty good.
The history about this is pretty clear.
