Craftsman 42cc Chainsaw Motor and Magneto Mount for RC Boat

thingiverse

I've been tackling a challenging RC Boat project where I'm trying to squeeze a Craftsman 42 cc chainsaw motor into a 3 foot long wooden fiberglass boat hull. The problem with a standard Craftsman chainsaw, however, is that the magneto mounts directly into the casing instead of being bolted onto the block like most two-stroke engines. To overcome this issue, I designed a custom motor and magneto mount system to ensure the motor would run smoothly. Given the limited space available in the boat hull, there was no room for the entire body of the chainsaw. Overcoming this obstacle has been quite an adventure, as I've had to carefully design a mounting system that fits within the specified dimensions while withstanding the forces exerted by the magneto and engine block. For this project, I'm utilizing PLA due to its ease of use and adequate strength for this application.
