    Impeller change

    What other parts should I have available when changing the impeller on a 1990, 90 hp. Force. Are there any gaskets, sealer, or other things necessary or do I just need to purchase an impeller?<br />Thanks for any help - I have a manual to work with but it is not real specific.

    Force ,1990, 90hp and Sea Foam

    Does anyone have any experience with using Sea Foam in a higher hp Force outboard? I am wondering about de-carbonizing and using regularily in the gas mix to minimize engine problems over the long haul. I have owned two Force outboards in the past and not had a problem with either but never...
