Question: What is the cover made out of?
Document: Perfect fit for my 115 four stroke. The cover looks great. Very durable and easy to take on and off.
This cover for the price is a nice product, not as substantial as the other factory Yamaha cover like the 250HP cover, but still very nice.
Cover arrived quick and fits by F115 motor very well, had to buy a new cover when i lost the old one.
Works fine. This arrived quickly and fit the motor securely, exactly as the ad promised. The fastening strap keeps it on, no matter what.
Perfect fit and condition - came as advertised and fits like a glove - I wish everything worked out this well
Just what I was looking for. It was engine specific and fit like a glove. Good price as well. Nice.
I know I live in the Florida sun, but after about a year in the elements this just got weak and brittle then tore. Total garbage, better off making your own as you are obviously paying for the Yamaha name
Answer: yes
