Indmar 9" Transmission Oil Cooler with Adapter Fittings – 495169

Keep your Indmar marine transmission operating at the proper temperature with this OEM Indmar 9-inch transmission oil cooler. Indmar part 495169 is designed to transfer heat from the transmission fluid into the engine's raw-water cooling system, helping maintain proper transmission operating temperatures during normal operation and heavy-load watersports use.

This 9-inch transmission cooler features 1-1/4" water hose connections and O-ring-style transmission fluid ports. Indmar later changed replacement coolers from the older NPT-style transmission fluid connections to an O-ring-style connection.

Adapter Fittings Included for Older Indmar Applications

Indmar 495169 includes adapter fittings that allow the newer O-ring-style cooler to connect to applications originally equipped with older 3/8" NPT (National Pipe Thread) transmission fluid fittings.

This is especially important when replacing an older Indmar transmission cooler. The original 90-degree NPT fittings from an older cooler may not thread directly into the newer O-ring-style cooler. The included adapters provide the connection needed for these older applications.

Why Replace Your Indmar Transmission Cooler?

The transmission oil cooler is an important part of an inboard boat's drivetrain and cooling system. Raw cooling water passes through the cooler while transmission fluid circulates through a separate internal circuit. Heat from the transmission fluid is transferred to the cooling water before the fluid returns to the transmission.

Over time, a transmission cooler can become corroded, restricted, damaged or develop an internal or external leak. A compromised cooler can reduce transmission cooling performance and may lead to elevated transmission temperatures.

If your existing cooler is leaking or showing signs of corrosion or restriction, replacement is recommended rather than risking transmission damage.

Fitment Information

Indmar used different transmission coolers, fittings, and hose configurations depending on the engine, transmission, boat manufacturer, and model year.

Always verify your existing cooler dimensions, hose connections, and transmission fittings before ordering.

The included adapter fittings make Indmar 495169 particularly useful when replacing an older 9-inch cooler that originally used 3/8" NPT transmission fluid connections.

If you are unsure whether this is the correct transmission cooler for your Indmar-powered boat, contact Bakes Online with your boat year, make, model, engine information and engine serial number, and our team can help verify the correct replacement part.
