• Also compatible with Sea-Doo RX DI 951 (2000–2003), XP DI 951 (2003–2004), and LRV DI 951 (2002)
• Verify against OE numbers like 278001241 and 278001554 for confirmation

How does this unit improve charging and electrical reliability?

The regulator-rectifier converts AC from the stator to stable DC and controls voltage to prevent overcharging. With its aluminum shell and copper windings, the design helps disperse heat during operation, reducing thermal stress on internal electronics and extending service life.

• Converts alternator AC to regulated DC for battery and electronics
• Aluminum housing improves heat dissipation under heavy load
• Quality wiring and tested components reduce early failures
• Replaces OE units to restore proper charging behavior

What should I check before buying to ensure compatibility?

Confirming fitment prevents returns and installation issues. Compare the Hocean-Max unit to your current part visually and by part number, check connector type, mounting hole locations, and coolant/venting clearances in the engine bay.

• Match OE numbers such as 278001241 or 278001554 printed on your original unit
• Compare connector pin count and orientation with your harness
• Confirm mounting bolt pattern and physical dimensions for a proper fit
• Inspect cooling access around the rectifier on your hull before installing

What warranty and quality checks come with the Hocean-Max regulator?

Hocean-Max tests every regulator-rectifier prior to shipping to verify electrical performance. The product includes a six-month warranty covering manufacturing defects; it’s not a replacement for damage from improper installation or other external causes.

• 100% tested components before shipment
• Six-month trouble-free warranty from Hocean-Max
• Buyer responsibility: visually confirm part match before purchase

Who is this for: This Hocean-Max regulator-rectifier is aimed at Sea-Doo owners, amateur mechanics, and marine service shops who need a dependable replacement for a failing charging component on 800 and 951 engines from the late 1990s to early 2000s. If you require restored charging performance, solid heat management, and a tested aftermarket option that replaces OE part numbers like 278001241, this unit is designed for that purpose. For long-term reliability, pair installation with a quick check of the stator, battery condition, and harness integrity.
