TRANSMISSIONS

Marine transmissions are the unsung heroes of the boating world. A marine transmission has three functions: to engage and disengage the engine from the propellers, to provide reverse rotation and to set the ratio between the engine and propeller revolutions per minute (RPM). At Discount Inboard Marine, we carry a wide variety of marine transmissions and marine transmission parts from the popular brands you trust, including Borg Warner and PCM. If you need product-specific information or technical assistance, reach out — we're happy to help.
