Keep your drivetrain running at the right temperature with the Indmar Transmission Oil Cooler, an inline marine heat exchanger designed to help dissipate heat from transmission flu id under load. By stabilizing operating temps, this cooler supports smoother shifting, consistent performance, and helps extend the service life of your transmission components—ideal for ski/wake boats and other Indmar-powered applications. Application: Marine transmission fluid cooling (inline installation) Brand/Vendor: Indmar Design: Cylindrical, metal canister-style cooler with inline ports and top-mounted fittings Function: Reduces transmission oil temperature by transferring heat away from fluid Install type: Fits into the transmission cooler line (verify hose size and routing for your setup) Why replace a transmission cooler? If your current unit is restricted, leaking, or contaminated, cooling performance drops and transmission temps can climb quickly. A fresh cooler helps restore proper flow and heat transfer. Fitment note: Indmar systems can vary by engine package and model year. Confirm compatibility using your boat/engine serial information and existing cooler line/port sizing before ordering. Availability: This item may be marked pre-order depending on current stock status. Show more
