Motorcycle mechanics repair and overhaul motorcycles, motor scooters, mopeds, and all-terrain vehicles. Besides engines, they may work on transmissions, brakes, and ignition systems, and make minor body repairs. Mechanics usually specialize in the service and repair of one type of equipment, although they may work on closely related products. Mechanics may only service a few makes and models of motorcycles because usually the dealers only service the products they sell. Boat mechanics, or marine equipment mechanics , repair and adjust the engines and electrical and mechanical equipment of inboard and outboard marine engines.
Most small boats have portable outboard engines that are removed and brought into the repair shop.
Larger craft, such as cabin cruisers and commercial fishing boats, are powered by diesel or gasoline inboard or inboard-outboard engines, which are only removed for major overhauls. Most of these repairs are performed at the docks or marinas. Boat mechanics may also work on propellers, steering mechanisms, marine plumbing, and other boat equipment. Small-engine mechanics service and repair outdoor power equipment such as lawnmowers, garden tractors, edge trimmers, and chain saws. They may also occasionally work on portable generators and go-carts.
