  • 1988 6sg 2 stroke power upgrade

    Does anyone know if this model can be upgraded to the 8hp 8sg with a carb change? Or if it would require more parts? Or if it is even possible or worth it at all.
    Thanks in advance.

        That model was manufactured until 1989, in fact your motor was manufactured in 1988.
        I gave a look to the parts manual and at 1st sight found 2 diferences.

        1 your main jet must be an #80 and for 8hp is a #98 (676-14943-26)

        2 the main noozle may be diferent but not sure.

        If you want to go ahead with this mod (at your own risk, I donīt think that may damage your motor but I can't say that you'll see an improvement) however by the price of the main jet (around $10) in my opinion I would try it.
        If youīll go ahead with this donīt expect a big improvement and the best way to probe it is with a tach.

        Just you can decide what to do...

        In case you'll go ahead than let us know the results.

        Good luck

          Thank you so much for the info. I was told by a dealer that the "tuner" is different also. He said that was what the exhaust was called. Do you happen to see a difference there? I'm a tinkerer so I might give it a shot. So you don't think going from 6hp to 8hp will yield much of a difference in feel or speed?

            Didnīt found any diference in the exaust...
            Best way to monitor the results is with a tach (tiny, small, chinese inductive tach to keep it cheap)
            If improves something is just 2 HP but yes, can make some diference depending the hull, prop and load on board
