Used a cowling cover on my 2008 Yamaha, stored outside and eventually sold it in 2015 . The cover looked like it was 25 years old, but the cowling looked new. I would also wax the cowling every couple years whenever I did the boat.
In general its the UV that trashes everything.... gelcoat, ttop canvas, seat cushions, gauge trim, even trailer tires. Anything you can shield from the sun, go for it you will be doing yourself a favor.
