Mercury Racing adds 2.08:1 gearcase to 150R V6 outboard range

1 min read

Mercury Racing has expanded its 150R V6 outboard lineup with new models featuring a 2.08:1 gearcase ratio, offering boat owners additional flexibility when matching engine and propeller combinations.

The higher ratio joins the existing 1.85:1 variants and is best suited to boats with top speeds below 90km/h, according to Mercury Marine, which says this is the bracket most likely to benefit from the change.

"By providing greater choice we are allowing both boat owners and our dealers to better match engine and propeller combinations to individual customer requirements," said Sean Bell, Mercury Marine Product Manager – Outboards ANZP. "The higher ratio will give boaters the ability to run higher-pitch propellers which can deliver improved top-end performance compared with the existing 1.85:1 option, while the large-displacement V6 powerhead continues to deliver the outstanding hole shot and mid-range punch that 150R customers expect."

The 150R is built around Mercury's 3.4-litre V6 powerhead, with Transient Spark Technology adjusting ignition timing to produce additional torque for acceleration. At full throttle, the engine develops up to 6000rpm. The outboard runs on regular unleaded petrol (91 RON) rather than premium fuel.

The new 2.08:1 models will be available in Phantom Black and Cold Fusion White, with L, XL and CXL shaft lengths. Stock is expected to arrive in Australia and New Zealand between December 2026 and January 2027.

The outboards include Digital Throttle & Shift, Active Trim, Adaptive Speed Control and Advanced Range Optimisation, and carry Mercury's six-year recreational warranty.
