1988 or 89 Yamaha 115HP vs the 130HP real difference?
I have a 1988/89 Yamaha with all the 130HP<br />labels and a 115HP serial number ?? Bought it very used from the repo man. Didn't get <br />much boat history. Whats the real difference? Jets ?, carb ?, timing ? And is it easy to ID the stuff any upgrade tricks to get the performance up ?? It's a strong runner. It will turn a 15" prop to 6000 RPMs<br /> on a 21 foot boat so I just got a 17" SS<br />to get it into the 5000 to 5500 range. Thanks :
