VIDEO: NEW MERCURY GEARCASE
Mercury’s recently launched range of FourStroke outboards isn’t just limited to new engines. The new offering includes redesigned engine gearboxes to produce an advanced 2.07:1 hydrodynamic profile, thus reducing drag and increasing performance standard on the new range.
Mercury quotes the new gearcase as having 15 per cent less drag than its previous offerings which were already race-tuned over many years (the 60hp Mercury Big Foot outboard motor has been long recognised as an exceptional option with well-recognised results).
Mercury has advanced the drive technology even further by offering an optional larger Command Thrust 2.38:1 gearcase to its FourStroke 90 and 115hp outboard models.
The Command Thrust gearcase will be very popular when powering heavier hulls and is also available with counter-rotation; however we just loved the extra bite and manoeuvrability, even when fitted to two identical Quintrex 530 Cruiseabout bowriders.
Videos: Mercury FourStroke outboard motors
We spent a couple of days reviewing new engines in the new Mercury FourStroke outboard motor range. As you can see, our video crew was kept very busy, as was engine expert Andrew "Engine Man" Norton and senior boat tester, John "Bear" Willis. Here's what they had to say.
Mercury Australia’s Anthony Brown explains what else is new, from significant engine weight savings to the SmartStart system that won’t wreck the starter motor.
