@emersonsc ( what was the outcome ? what did they end doing for you and did he explain some of the cause's you had mentioned ? )
They are having us send the 1st new motor with the failed oil pressure so they can take it down in MN and find the cause. They had told us that they WERE having issues with the coolant gelling, but that was almost 2 years ago, and they had sense changed vendors, along with their oil & brake fluid vendor. The fluids they use are from a company in france, I believe it was ALF or ELF or something along those lines. They said this year they only sold 6 engines, and 2 of those were from us.
The ended up replacing the whole unit for us which wee couldn't believe and were very grateful for!
So far, they have been VERY good about tech support, part support, and warranty. Far better than I have had dealings with when I owned Arctic Cat and Polaris units.
