    I recently bought a 1994 J16 Carolina Skiff with a 1992 Johnson 30 HP tiller for $1000. Motor has been sitting up for 2 years but ran for about 5 minutes before not pumping water out anymore. Plan on replacing water pump, impeller assembly, & thermostat to try & fix that problem.

    But what I want to know is I see where people are converting 20 & 25 HP motors to 30 & 35 horses....I am interested in this, can this be done with my motor?

    The way to increase horsepower is to throw money at it.
    Need to ask yourself is it worth the time, effort and expense?
    It's a 20 year old outboard, if it's been a saltwater outboard
    there's no telling what you'll find when you pull her apart.
    Your decision, me...I'd find something else to spend money on.
    Like a new yami 40 4 stroke.  ;)

    btw, it's been done and documented pretty well

    20-25-30-35 hp upgrade
