Re: it is possible upgrade my mercury 15 hp to 20 hp?
just my two cents,but,its a 2010?buy new?why not buy a bigger motor in the first place?If you got on a boat deal then little different(not much).It may be possible that it can be done but it will be pretty costly,especially for the VERY SMALL performance boost you will see.we re not talking adding much at all here in the way of hp.Is a couple(literally)mph worth several hundred dollars.Of course what type of boat its on will affect how much increase in performance youll get.Im not trying to be mean OR talk you out of anything,just think youll be pretty disappointed in what youll get for what you spend.Again,jmo.
