just wondering if those ice scratchers are gimmicky or do they actually work to keep engine from over heating. i realize you can't go in reverse with them, but looks like a smart idea in general ....can u get after market for any sled?
They will drop the engine temps about 30 degrees. In hardpack or icy conditions, they are very necessary, especially if the sled has had the bogey wheels deleted. The wire ones work better, the cable ones are more convenient.
