SR 440 Mercury
I actually have two of these. One 1974 and a 1975.
The 75 I have owned since about 1979. I have not ridden it since about 1982, and never did ride it much because of clutch and starting issues. Looking back I realize the crank seals are bad. At the time it sure seemed fast when it did run!! But, I always have had a soft spot for Mercs even before I knew of the sno-twisters. Maybe because they are a little different?
I also have just purchase a 1974 SR 440.
I guess I plan on evaluating what I actually have between the two sleds. They may become one, or if I decide it is feasible, I will get both of them going. These will probably not become show sleds, just some fun sleds to bounce around on:)
The "New" 74!

I finally have the 74 home. I have ridden it, and it runs pretty decent. I little TLC to do, and get some "action" pictures!
I don't have any pictures of the 75. It is still tucked away, and will probably remain that way for a little while.
