I'm considering buying a '95 Ranger R70 Sport, rated for 130hp. It has a '95 Evinrude 115 Intruder. Is there a way to get more umph out of the 115, and would the gain be worth the expense? Upping it to 130-140?

An upgrade in power is going to cost you a pretty penny. A 115HP engine will run you approx. $10,000 and a 140 HP is approx. $12,000. The bad part is if you put a $10,000 engine on a $2,000 boat you still have a $2,000 boat. This is why not many people do not repower and find themselves a nice used boat for the price. I hope this helps and have a good day.

Thank you for your time. I was thinking of performance mods for the 115.
