⚠️ Important Fit Notice This cover is engineered for a secure, snug initial fit, which may cause the impression that it “does not fit.” That tightness is intentional, ensuring the best long-term protection.
For a smoother initial installation:
Lightly apply marine wax to the cowling to ease sliding.
Warm the cover in direct sunlight for a few minutes to soften the SurLast material.
Once installed, the fabric will relax and conform to your cowling—providing a custom, secure fit.
