Vehicle Information
Yamaha SL396 Snowmobile (1969)
The 1969 Yamaha SL396 is a classic snowmobile, powered by a robust 396cc twin-cylinder, 2-stroke engine. This air-cooled powerplant delivered 27 brake horsepower at 6,000 revolutions per minute, offering reliable performance for its era. As a standalone model, the SL396 was a significant offering in Yamaha's snowmobile lineup, building on innovations from earlier models like the SL351, likely featuring Yamaha's oil injection system and slide-valve carburetors for enhanced power delivery and convenience. Information available does not indicate that the 1969 Yamaha SL396 was offered in different trim levels; it appears to have been a singular model. While other Yamaha snowmobile models such as the SL351, SS396, SS433, SW396, and GP396 existed concurrently, these were distinct models rather than variations of the SL396. There is no specific mention of mid-cycle generation or engine changes occurring within the 1969 model year for the SL396. Its engine's belt-drive oil pump system was also consistent across 1970 and 1971 models, with some components shared or evolved across the 1969-1971 Yamaha GP, SW, and SL 396 series. Q: How can I ensure I select the correct parts for my 1969 Yamaha SL396?
A: To guarantee a perfect fit, please use the year, make, and model selector at the top of the page to specify your exact snowmobile.
