I have a xf 7000 with the Yamaha motor. I had to replace my actuator. When I got if from cat he said new part number, meaning they have been upgraded since mine was put in at the factory. My sled is a 2014. I see no physical difference. Installed it last week, so early to tell, but it works fine.
Also for you guys that are having issue when cold, Yamaha was having issue with all relays, including fuel. They make a cold weather relay, you can get new cold weather for like $12, If yours are the cold ones they will have a red dot, if not I think the ones that are failing have a blue dot. So you may want to check all relays to see if cold weather, your fuel pump for sure.
