I have seen posts on here where the Doo 550 fan motor is said to have problems but never actually said what they were. Any info on this motor?
 
The 550 fan has no problems!!! Very good little 70 HP engine when in rev chassis. They are jetted a tad lean in the mid engine but thats not a problem, just a slight tuning with some needle shims.

Good Luck
 
Hep they got problems they never break.Just the exhaust leaks but with a few nord lock washers they are fine. I ride with a guy that has 2 and he has over 5000 miles on both sleds.

Thanks, I am looking at getting a 2009 skandic tundra lt with the 550 fan motor. I need a 2 up sled to get gear and people than don't want to drive a sled around in the CO mtns. It has a 16x154 track with electric start and reverse and weighs 499 and a decent price.
 
That's a great sled, and what the guys are saying is true, the 550 engine is bulletproof. There are a lot of 550 skandics around here, some with over 25000 km's and still going! The only complaint I've heard is that it's bad on gas for a 550 fan.
 
Just last week I was drooling over an '08 Skandic WT 600 fuelie.

20 x 156
600 SDI
Enough room for both Ma AND Pa Kettle, big windershield, GPS port, and pulling a sleigh full'a gas and gear gits 12mpg on the river @ 50mph! :eek:

I wished I'd had that sled last week! :o
 
....or .... just buy a two-up seat to put on one of your many extree sleds. :light:

...but then I know how you git itchin to buy "somethin' ". :confused:


BTW - have you got that 4wheeler back together yet?


Just might be headin' back north next weekend if the weatherman is willin' to be bribed for one more week. Gayle's claimin' 6' in the bush yet, and their still runnin' the bloody groomers! Plannin' on campin' out. You commin'? (Either hafta bring a gen set - or leave your bloody electric blanket to home! :rolleyes: )

headin west as soon as I can get away, so no heading north this year.

are you saying 10 sleds is too many for one guy?
I plan on getting rid of 2 or 3 if I buy the Skandic

did get my 4-wheeler running to plow snow, just no brakes yet
