    Smile Kits

    These kits are about 15 years old. One was in the sealed box and the other (pictured) was taken out for the photo shoot. I got lucky, my friend Cadillac sent me a Craigslist add. They were $1000.00 each. Not much if you need them (which I do). I will add more detailed pictures soon.
    The guy I got them from said he was holding on to them in hopes of someday getting a 4 cylinder Donzi. Glad he didn't know much about computers.

    The kits are probably more than 15 years old. M&W Gear Company is/was located in Gibson City, IL. The marine turbo kits were offered in the early to mid 80's and possibly even earlier. I spoke with the engineer there back in 1988 about those kits. They were a pretty good low boost (4-5 psi) kit designed for stock engines requiring no internal modification. The result was a respectable performance gain of 8 -10 MPH on V8 engine around 350 cu. in. I don't remember the performance increase on the 4 cylinder setups.

    I agree.

    That you for the info. To add, from what I found may go back as far as 1974. The guy I got these from said there were a distributor for M&W and that they were saving them for a project that they didn't even have yet. He said the turbo chargers would fit and Mercruiser but that the rest of the kits are only for the 4 cylinder versions, which is what I have.
    These would have cool on a twin Bertram IO with twin 160 HP 4 cylinder engines.. One will be good for me. I have 120 HP. May go to 130 or 140??
    Thanks again.

    I know someone who was running one of the M&W turbo setups on a 350 SBC Merc Alpha in a 20" Cigarette 25+ years ago. The V8 kits were dual turbo setups and used the original Merc exhaust mainfolds. I don't know the exact speed of the Cig, but it was very fast. It was faster than all but a few boats on our lake. In fact this boat was dialed in by Bam Marine when they were located at Marina City in Chicago.

    Turbo test results

    Here is an article written in 1974 about the M&W turbo chargers tested on a 165HP Mercruiser. Interesting.
