[QUOTE="PolarKraft, post: 419338, member: 17040"] I have a Yamaha 1997 40/28 jet drive outboard model 40EJRV. This is the same motor used in the 50 HP 50EJRV. All the part numbers are the same between the two for carburetors, jets, reed valves, intake, pistons, crank, engine block, head, electronic CDI ignition. What is used to add 10 HP and between the two motors? [/QUOTE]
