Indmar Marine Fuel Filter – EFI All Models | Part #556003 Protect your Electronic Fuel Injection (EFI) system with this genuine Indmar fuel filter, compatible across all Indmar EFI marine engine models. Clean fuel delivery is critical for EFI engines — even small amounts of dirt, rust, or debris in the fuel line can clog injectors, cause rough running, and lead to costly fuel system repairs. Compatible with: All Indmar EFI marine engines fitted to Brands like Malibu, Moomba, Supra, and Tige boats.

Indmar Marine Oil Filter – GM 22mm Single | Part #872024 Protect your GM-based Indmar marine engine with this genuine Indmar 22mm single oil filter. Precision engineered for GM marine engine applications requiring the 22mm thread specification — correct filter sizing is critical for a leak-free seal and proper oil system function. Never substitute an incorrectly sized filter — an improper thread fit risks oil leaks, filter bypass, and catastrophic engine damage. Compatible with: Indmar GM marine engines requiring 22mm single oil filter fitment on Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment for your specific model year

Indmar Marine Spark Plugs – Set of 8 | LS1 / LQ9 / LY6 / L96 / LS3 Engines | Part #491012 Keep your Indmar LS-series engine firing cleanly and consistently with this genuine Indmar spark plug, covering the LS1, LQ9, LY6, L96, and LS3 engine families. The LS-series engines are among the most respected and reliable marine powerplants ever built — and keeping the ignition system in top condition is the key to maintaining their legendary performance and longevity on the water. Compatible with: Indmar LS1, LQ9, LY6, L96, and LS3 marine engines fitted to Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment for your specific model year before ordering.

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 Coil – L96 / LS3 / LSA Engines | Part #551756 Keep your LS-series Indmar engine firing at full strength with this genuine Indmar ignition coil for L96, LS3, and LSA marine engines. The LS-series uses a Coil On Plug (COP) system — one individual coil per cylinder sitting directly on each spark plug. A failed coil on a COP system causes an immediate single cylinder misfire — easily identified but requiring prompt replacement to protect the catalyst exhaust system from unburnt fuel damage. Compatible with: Indmar L96, LS3, and LSA marine engines fitted to Malibu, Moomba, Supra, and Tige boats. Contact us to verify fitment
