    Possibly, but unknown. It was more like a Mercury T2-X protruding thru the narrow cowl.

    Sounds great but can you do a video on the exhaust side.

    What size that chamber needs to be? Is there some formula to calculate it?

    Experimentation suggests that 150% of the exhaust port area with a 25% choke immediately downstream of the #3 cylinder followed by a 3 degree divergence cone is a good starting point.
    Best of luck!

    Started on an exhaust system for the stock 49ci 3 cylinder OMC Stinger based upon the Mod 50 exhaust. Found the information you posted and others very helpful. Parts have been casted and are awaiting machining. It will be some time until it will be tested. Will try to post some pictures when completed. There are quite a few guys here in AU who are interested.

    I have been insanely busy but my 75 is togeather I had to Modify the pan and hood for my exhaust but it turned out looking good. I'll get more picks when the snow clears.
