Re: johnston 35hp outboard
Probably by fitting a 25 hp carburetor on it.<br /><br />But, why would you ever want to do this? Is there some legal inspection that the 35 is failing because the boat is rated for less maximum power? You never hear about anyone wanting to LOWER their boat's power.<br /><br />Also, Johnson made 35 hp engines from 1957 up to recently. What year engine is yours?
