UIM changed the rules a few weeks ago and increased the cylinder volym to a maximum of 2.1 liter in this popular class.
Now Mercury Marine´s new 115 four stroke is going to be the engine of choice for the racers.
I guess a few used Merc 115 XS and Evinrude 115 H.O. is going to be available on the used market for outboards.
Good or bad..I don’t know but time will tell..
Here is the weight…Evinrude 115 2 stroke 177kg – Mercury Marine 115 2 stroke 170kg – Mercury Marine 115 4 stroke 163kg..the four stroke is not as heavy as the 2 stroke and have way larger CC.. maybe the 2 strokes can keep up with the 4 stroke..I don’t know..!!
PS: The same new 2.1 liter rule is also for the Offshore 3 A class
