Outboard Racer George Martin was convinced that his "poppet valve" intake method for 2-stroke motors would revolutionize the boating industry - and in 1946, he introduced the first production models under the "Martin" name - through an odd royalty based manufacturing agreement with the National Pressure Cooker Company.
They made roughly 300,000 motors through 1954. When they couldn't keep up with the horsepower race in the late 1950's, the company simply folded and spare parts were sold to a private party in Wisconsin.
Models included the 20, 40, 45, 60, 66, 75, 100 and 200. Each model number roughly translated to engine horsepower (e.g. 40 and 45 had 4.5 HP)
I have quite a few Martin motors in stock. They are good runners, relatively easy to maintain, and you can still get some parts from Larson Outboard Service.
I have 2-40's, 2-60's, 2-75's and a 66. Check out photos of one of the 40's and the 66 below!
