Indmar Marine Lower Thermostat Housing – Low Profile E-Coat | Part #531069E
Seal and protect your cooling system with this genuine Indmar lower thermostat housing, featuring a durable E-coat (electrocoat) finish designed to resist corrosion in the harsh marine environment. The low profile design ensures a clean, precise fit in tight engine bay spaces — common in modern wake boats where engine compartments are compact.
Compatible with: Indmar marine engines fitted to Malibu, Moomba, Supra, and Tige boats.
What is E-Coat and why does it matter?
E-coating (electrocoating) is an advanced corrosion protection process where paint is applied using an electrical current — the same process used in automotive manufacturing. The result is a uniform, highly durable finish that gets into every cavity and corner, providing superior rust and corrosion resistance compared to standard painted or bare metal housings. Ideal for the wet, demanding marine environment.
What is Low Profile?
The low profile design reduces the overall height of the thermostat housing, making it ideal for engines with limited clearance in the engine bay. If your original housing was low profile, always replace like for like — a standard height housing may not fit correctly.
When should you replace it?
Replace your lower thermostat housing if you notice coolant leaks around the lower housing area, visible cracks, corrosion, or warping. Replacing the housing, gasket, and thermostat together at the same time is best practice and saves labour costs.
