Re: More horses for my Mariner 30?
I have the same engine, only 1 year newer. These are great engines, very tough, mine was overheated 2 years ago and seized up, after cooling down it started back up and hasnt missed a beat.<br /><br />Weight is around 120lbs for this engine. I have a set of doel fins on mine, not sure how you can add horsepower- I think the 20/25/30/40 are all the same block- not sure how to gain the extra 10 hp.<br /><br />By the way- this is a yamaha engine with mariner decals on it- u can see yamaha symbols all over the power head and such if you look well enough.<br /><br />That said- yamahas of the same vintage can swap parts.<br />-John
