Mercury optimax fuel economy

Hi All Took the boat out for a run with the new Opti last Saturday to get some run in time up, thought some may be interested in the fuel consumption. Bear in mind that it was run in time and accordingly was up and down on the throttle the whole time. Will be interesting after it is run in completely and can maintain normal operating speeds Cheers Bill. That must have put a smile on your face when you refueled,Bill. Thats great fuel economy for a straight out of the box. Bound to get even better when it loosens up a bit. So who said 2 strokes are a dying breed!

Mercury optimax fuel economy

The least powerful of a trio of Direct Fuel Injection two-strokes from to hp, the OptiMax produces substantially more torque than its 2. The has all standard OptiMax features, such as the dual-stage Orbital Combustion Process OCP , a massive 60amp belt-driven alternator and SmartCraft instrumentation which displays fuel flow, range-to-empty, engine cooling water temperature and pressure, and alternator charging voltage. The OCP utilises a combination of stratified and homogenous combustion with low-pressure injection of petrol and air at 5. This results in significantly greater fuel flow, but still only around 15 per cent more than comparable-output four-strokes, which return maximum fuel efficiency in the to rpm range. Providing the antiventilation plate was kept at least three-quarters immersed, power astern was good and no cooling water starvation occurred. Vibration levels across the entire rev range were very low but the normal Merc V6 howl was present above rpm, making the engine somewhat noisier than comparable four-strokes. Pushing a total of kg, including two adults, the trolled us at 5. However, by rpm on homogenous mode, averages were A clean plane was achieved at only rpm averaging At rpm we averaged

Once again, the Truth Is The Proof. Therefore the very least amount of oil we used for my holidays was say litres. Fast cruise was 62 litres an hour and flat out was

The 2. In carburetted and EFI form, it can develop up to hp. The combination of a relatively low WOT wide open throttle range — from to rpm — plus big cylinder bore and short piston stroke ensure its long lifespan. Unlike some of its four-stroke competition, the Mercury OptiMax outboard motor is a true marine engine with a diecast alloy cylinder block and head designed to handle the rigours of direct saltwater cooling. Spare parts are readily available and Mercury even offers a rebuild program for the powerhead. This differs from the Evinrude E-TEC system in that it injects atomised air and fuel rather than just straight fuel via unit injectors, as occurs in a direct-injection car engine. However, this is as lean as overall in the combustion chamber.

However, that is not the case with the Mercury OptiMax outboard motor. Its big-displacement three-cylinder powerhead sends waves of vibration through the hull structure at leass than rpm, guaranteeing gentle flab reduction whenever you grip the hull or steering wheel. A belt-driven, voltage-regulated 60A alternator provides plenty of power for electronic toys and since the only other belt is for the air compressor, the is relatively trouble free compared to hp four-strokes. The dry weight is kg for the longshaft version kg for extra-long and the gear ratio 2. Powerhead access is good even though a 4.

I would try and find someone who has done that before you do it. Remove Advertisements. Anything else that would add weight? That would put my 20' SeaOx, with gallon tank, range at about miles. We went round the island on easter sunday and burned 75ish litres without much effort at all. Most of it was at high speeds as it was so flat but your figures have made me feel better!

Undoubtedly, no other brand makes outboard motors more powerful, efficient, and reliable than Mercury Marine. Especially the Optimax series of outboard motors are known for delivering the most fuel-efficient and top-speed performance.

Regards Craigie. Probably the biggest variable is just how much of your engine's hp are you actually using the way you use it. Might have missed the first night I filled it up so another litres so litres total. It's about 25 or 26 bucks regular price for 5 litres at places like supa cheap auto, or about 19 to 22 per 5 litres on special. Thanks Bill, good to see some real figures. Cheers for the reply Gary, 30 - 50L and hour All of my boating is done in Poole in Dorset, its a family boat and we rarely ever go on long trips out of the Poole kind of area.
