Mike,
Here's why the rad+fan won't work for that application:
http://www.dootalk.com/forums/index.php?sh...t&p=1492100The Skandic SUV on the Yeti chassis was one of the best utility sleds built by BRP. Although the comfort level of this chassis was not quite at the level of the Yeti II, it had better deep snow and maneuverability traits. Many features put the SUV above previous offerings from BRP:
(1) Mtn Bar
(2) RCG rear skid
(3) Higher seat and riding position
(4) Twin-bulb headlamp
The rear skid was definitely the biggest improvement over previous offerings.
4600mi should be a joke for the engine, ideal compression is around 120psi, anything better than 105 is not too bad, engine will still run at 100psi, but you're looking for a rebuild by that time. The standard 593 engine in the SUV was a reliable, strong and fuel efficient engine; it's now called the 500SS in some of BRP's current sleds and has been in the lineup since 1999. Cooling is no different for this engine than it is for any other Rotax liquid cooled twin. If you're running on bare ice or crusty snow (i.e. late Spring, early morning frost) you will need a set of ice scratchers, that's all.
Biggest concern here is the gearbox. Ask him if he has ever had the brgs replaced and test all gears before buying. A rule of thumb for Skandic/Expedition owners is that the gearbox brgs should be replaced every 10000km's or so (6k miles ish). This gearbox is worth more than the sled most times, so inspect it and if you buy it, get ready for the 6000mi rebuild at your dealer.
$3000 USD is a steal. A replacement seat cover from a good upholstery shop will run you $100.
Today went over there to look at the machine. It has 125psi compression in both cylinders, bearings have not been changed in the gear box, rear suspension has been rebuilt with new parts, seat is ripped, backrest leans to one side (indicating a roll or laid on it side), left trailing arm has been broken and rewelded, oil light stays on with oil in the reservor, hand warmers work, gear case works, cowling had a gun strapped to it so the cowling got hot and kind of deformed the it, steering post looks straight, tub and tunnel look straight, summit skis are installed, track looks good and the gear case oil looks like it needs to be changed. Drive shaft bearing has been replaced also. Tell me what you guys think.
