Hocean-Max Voltage Regulator Rectifier for Sea-Doo GSX/GTI/GTX 278001241, Aluminum Housing Tested

Hocean-Max Voltage Regulator Rectifier 278001241 is a drop-in replacement regulator/rectifier engineered to restore stable DC charging for compatible Sea-Doo personal watercraft from the late 1990s to early 2000s.

This replacement unit is built with an aluminum housing and quality copper windings to help dissipate heat and maintain consistent voltage output for the charging system. It’s designed to match several OEM numbers and fit a range of Sea-Doo models including GSX RFI 800, GTI RFI/LE 800, and multiple GTX and DI 951 variants. Each Hocean-Max regulator is bench-tested for electrical performance and supplied with a six-month limited warranty; confirm the part number and connector shape on your original unit before ordering.

Which Sea-Doo models will this regulator work with?

This Hocean-Max part is compatible with many Sea-Doo models produced between 1998 and 2004 that use the same regulator/rectifier footprint and electrical connections. Check your existing part number and visual connector match to ensure fitment before installation.

• GSX RFI 800 — 1999–2000
• GTI LE RFI 800 — 2003–2004
• GTI RFI 800 — 2004
• GTX RFI 800 — 1998–2002; GTX DI 951 — 2000–2003
• LRV DI 951 — 2002; RX DI 951 — 2000–2003; XP DI 951 — 2003–2004

How does this regulator improve charging reliability?

By converting AC output from the stator into stable DC for the battery and electrical system, the regulator prevents overcharging and voltage spikes that can damage electronics. The aluminum shell and copper wiring improve heat dissipation and electrical conductivity compared with lower-quality replacements.

• Aluminum housing disperses heat to reduce thermal stress
• Copper windings provide consistent current flow
• Pre-shipment testing ensures correct voltage regulation

What should I check before purchasing and installing this part?

Confirm the OEM part number and visually compare connector locations, mounting holes, and plug shape against your original regulator. The seller recommends matching the listed replacement numbers to avoid ordering the wrong unit.

• Match original part numbers: 278001241, 278001554 where applicable
• Verify connector type and five- or six-terminal layout against your unit
• Inspect mounting hole spacing and overall housing shape for fitment

What warranty and quality checks are included?

Hocean-Max conducts electrical performance testing on each regulator and controls component quality before shipment. The product comes with a six-month trouble-free warranty to cover early defects; follow return instructions if the part fails within that period.

• 100% tested for voltage regulation and rectification
• Quality-controlled components and assembly
• Six-month limited warranty from the seller

Who is this for: This Hocean-Max regulator/rectifier is aimed at Sea-Doo owners, marine mechanics, and restoration projects that need a reliable, cost-effective replacement for aging or failed charging components. It’s suitable for hobbyists comfortable verifying part numbers and performing basic electrical and mounting checks before installation, as well as professional shops servicing compatible late-1990s to early-2000s Sea-Doo watercraft.
