Just traded a 60 etec with my 450 hornet as it fried the emm the week before christmas only after 160 hours. BRP came to the party and replaced it even though it's 2009 motor. The distributor in Orange handled it all. This is the main reason for sticking with the etec, good service close bye. I'm certain once you sort out your 135ho you wont regret your choice, just have to go through the short term pain.
As far as I understand it's the V4 115hp motor, with 115 performance at bottom and mid range and a top end 99hp (90hp) I'm lead to believe that the 3 cylinder 90 is performing at it's max.
Plan was for the girls to come out a couple of times a year on the biscuit, hence the ho. Just hope she's not too much weight on the rear end thats all.
