Yamaha 4.2L V6 F225 F250 & F300 Offshore Deluxe Outboard Cowling Cover – 2019 and Earlier – MAR-MTRCV-F4-2L
⚠️ Important Fit Notice
This cover is designed for a tight initial fit to ensure maximum long-term protection. This may cause it to feel like it “does not fit” during the first installation.
For best results:
- Apply a light coat of marine wax to the cowling.
- Warm the cover in direct sunlight for several minutes to make the fabric more flexible.
Once installed, the cover will naturally stretch and mold to your cowling for a secure, custom fit.
Product Overview
The Yamaha 4.2L V6 F225, F250 & F300 Offshore Deluxe Outboard Cowling Cover – 2019 and Earlier – MAR-MTRCV-F4-2L is engineered for precision protection in harsh marine environments. Made from SurLast solution-dyed polyester, it delivers long-lasting defense against UV rays, moisture, mold, mildew, and abrasion—while remaining gentle on your motor’s finish.
The non-abrasive lining safeguards your cowling during storage and transport, and the adjustable snap-buckle strap ensures a firm, secure fit even in challenging conditions.
Note: Not compatible with newer Yamaha Offshore model variants such as XSB, NSB, NCB, or XCB series.
Key Highlights

- Heavy-duty SurLast polyester resists UV, moisture, mold, and abrasion
- Non-abrasive lining protects the cowling’s finish
- Secure snap-buckle strap for a tight, wind-resistant fit
- Breaks in over time—initial snugness is intentional for lasting protection
Frequently Asked Questions
Q: Why does the cover feel too small at first?
A: The snug fit is intentional for optimal long-term performance. It can initially seem too tight or the wrong size. Waxing the cowling and warming the cover in sunlight before installation makes it more pliable for easier fitting.
Q: Will this cover fit the latest Yamaha Offshore models?
A: No. It’s designed only for Yamaha 4.2L V6 F225, F250 & F300 Offshore engines from 2019 and earlier, not for newer XSB, NSB, NCB, or XCB variants.
Q: What makes SurLast fabric ideal for marine use?
A: SurLast is solution-dyed for superior color retention, resists UV degradation, repels water, and prevents mold and mildew—all while being gentle on the cowling finish.
