Yamaha 9.9 conversion to 15

[petren]

Hi all, I have a 2005 Yamaha 9.9 that has been modified or so I'm told to 15HP(2 stroke). How can I tell without taking it apart if that is the case. I have it on a Zodiac FR340 and it moves quite nice with 3 adults and two kids at about 30km/h and about 3/4 throttle. Would a 9.9 alone be able to do that or that's the 15 horses that push along?

Thank you,

Nick

throttle stop is one item and you could undo the carb from the reed block and post a pic and i can tell you if it is a 15hp reed block

Hi Hugh, can you send me the link to your thread of converting the 9.9 to 15.

Looking at doing this to a motor I may get hold of.
