Jabsco 37004-1000 Marine Toilet Base Assembly Kit

The Jabsco 37004-1000 is a complete toilet base assembly designed as a direct replacement for Jabsco Series 37010 Electric Toilets, as well as 37045, 37245, 37075, and 37275 series marine toilets. This comprehensive kit includes all essential components needed to restore or repair your marine head base system.

What's Included:

• Complete base assembly
• Joker valve (anti-backflow check valve)
• 1-inch discharge port
• Phillips head mounting screws
• Starlock washer
• Hex nuts, plastic washers, and stainless steel washers
• Nut cap

Important Note: The base to bowl O-ring seal (P/N 44101-1000) and base to macerator O-ring seal (P/N 43990-0066) are NOT included and must be ordered separately if needed. Additionally, the discharge port included with this base does not fit 37075 or 37275 toilets—use discharge port 37077-1000 instead for those models.

This genuine Jabsco replacement part ensures reliable performance and proper fit for your marine toilet system. The included joker valve prevents waste backflow, while the complete assembly simplifies installation and maintenance.
