Dowco Marine Universal Outboard Motor Cover Size Medium (M) 300 denier solution dyed polyester with a brushed trico backed coating. Brushed trico back provides a soft underside that prevents scratching, scuffing, and maring on the motor hood. Fits motor hoods with a max circumference of 69". Note: Circumference is measured around the motor hood at the largest point, usually where the motor hood separates from the outboard. Measuring and fitting the motor hood cover at this location is the most accurate way to select the correct motor cover. 3 year limited warranty. Made in the USA.
