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.

Indmar Marine Ignition Wire / Spark Plug Leads Set – Black Small Block HVS | Part #751106 Restore crisp reliable ignition performance with this genuine Indmar black ignition wire set for the small block marine engine with High Voltage Switch (HVS) ignition system. A complete wire set is one of the most impactful ignition upgrades you can make — delivering clean high voltage pulses from the HVS distributor to every spark plug for consistent firing across all cylinders all season long. Compatible with: Indmar small block marine engines with High Voltage Switch (HVS) ignition systems fitted. Contact us to verify fitment for your specific model year before ordering.

Indmar Marine Ignition Coil – GM 1995 & Later | Part #556132 Restore strong reliable spark with this genuine Indmar ignition coil for GM-based Indmar marine engines 1995 and later. The ignition coil converts battery voltage into the high voltage spark energy needed to fire each cylinder — a failing coil means weak spark, misfires, and eventually a no-start condition on the water. Compatible with: Indmar GM marine engines 1995 and later fitted to Malibu, Moomba, Supra, and Tige boats.

Indmar Marine Formed 1" 90° Hose | Part #841033 Maintain leak-free cooling System flow with this genuine Indmar 1 inch 90-degree formed hose. Pre-formed to the exact OEM shape, this hose fits perfectly first time — no bending, kinking, or makeshift modifications needed. Purpose-built for Indmar marine engines where precise hose routing in tight engine bays is critical. Compatible with: Indmar marine engines fitted to Malibu, Moomba, Supra, and Tige boats.

Indmar Marine Circulation Water Pump Kit – LY6 / L96 / LS2 | Part #556381 Restore reliable coolant flow with this genuine Indmar water circulation pump kit for LY6, L96, and LS2 marine engines. A complete kit containing all components needed for a full circulation pump replacement — no sourcing individual parts separately. Compatible with: Indmar LY6, L96, and LS2 marine engines

Indmar Marine Raw Water Pump – Full Barb | Part #685001 Keep your cooling system flowing with this genuine Indmar raw water pump, full barb configuration. The raw water pump is the heart of your Indmar engine's cooling system — responsible for drawing water from outside the boat and circulating it through the heat exchanger or raw water cooling circuit to keep your engine at the correct operating temperature. Without a functioning raw water pump your engine will overheat rapidly and catastrophically. Compatible with: Indmar marine engines with raw water cooling systems
