Indmar GM 5.7 2006 – 2018

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 Impeller Pump Gasket – Johnson | Part #685008 Never reuse an old gasket — this genuine Indmar Johnson pump gasket is the correct OEM replacement seal for the Johnson raw water pump fitted to Indmar marine engines. A small but critical component that ensures a leak-free seal on your raw water pump — protecting your cooling system integrity and keeping your engine at safe operating temperature all season long. Compatible with: Indmar marine engines fitted with Johnson raw water pumps on Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment for your specific model year before ordering.

Indmar Marine Raw Water Pump Impeller | Part #685007 The single most important annual service part for your Indmar engine — this genuine Indmar raw water pump impeller should be replaced every season without exception. A healthy impeller means a healthy cooling system. A failed impeller means no cooling water flow and a catastrophically overheated engine in minutes. This small rubber component is without question the cheapest insurance policy you can buy for your Indmar marine engine. Compatible with: Indmar marine engines with Johnson raw water pumps fitted to Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment for your specific model year before ordering.

Indmar Marine Raw Water Pump Bracket Kit – 5.7L | Part #495200 Ensure your raw water pump is correctly and securely mounted with this genuine Indmar raw water pump bracket kit for the 5.7L marine engine. The pump bracket is the structural foundation of your raw water cooling system — holding the pump in precise alignment with the drive belt and engine block. A worn, cracked, or incorrectly fitted bracket causes pump misalignment, accelerated belt wear, bearing failure, and ultimately cooling system breakdown on the water. Compatible with: Indmar 5.7L marine engines

Indmar Marine Water Pump Circulation – 383 / 350 | Part #551045 Keep your freshwater cooling circuit flowing with this genuine Indmar water circulation pump for the 383 and 350 cubic inch marine engines. Unlike the raw water pump which draws water from outside the boat, the circulation pump moves coolant through the closed freshwater cooling circuit — maintaining even engine temperature across all operating conditions. Compatible with: Indmar 383 and 350 cubic inch marine engines
