I have a Bob-Cat snowblower made by Wisconsin Marine. It has a 7HP B&S # 170452 1403 01 78073112. I believe this is the original engine, which would date this machine at 1978. I bought it second hand and used it from 1988 to 2006 and it threw snow like crazy. I bought a new machine, since this one had some drivetrain issues and only had a 2sp transmission.
It sat for 5 yrs in a shed and then 2yrs outdoors. I just now dragged it out of the snowbank to resurrect it. The engine is not siezed, but needs some TLC. The hi-range chain is loose, and skips cogs. The chute was rusted solid and would not rotate.
Wish list: Engine tune-up/carb rebuild, change high range sprocket ratio to increase speed in high range, fix ball & detent thingy in trans so it stays in gear, new tires, fix chute rotator and add remote deflector control.
