Go Devil Motors

Go-Devil motors are known as the “four-wheel drive” of boat motors. These surface drive engines will get you to parts of the backwaters that others dare not traverse. Mainstream carries a full line of Go-Devil motors, including our most popular 23HP Vanguard GO-DEVIL® with long shaft.  You will not be disappointed in the performance and dependability of this engine, ideal for 16- to 20-foot boats.
