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 OCPa massive 60amp belt-driven alternator and SmartCraft instrumentation which displays fuel flow, range-to-empty, mercury optimax fuel economy, engine cooling water temperature and pressure, and alternator charging voltage.

Take a look at the facts. Better still, for the ultimate proof, take an OptiMax out on the water. The OptiMax range combines lightweight, compact design with state-of-the art, direct-injection technology to produce optimum performance on the water. Thanks to an exclusive low pressure two-stage direct-injection process, a burst of air and fuel are mixed together forcing a fine mist of microscopic, atomised fuel and air particles directly into the cylinder. The particles burn quicker, cleaner and more completely. So right from the time you start it up, OptiMax is quickest out of the hole, every time.

I have averaged out your figures from your maiden voyage, 1. The reason we used XD was it was a borrowed boat and that is what the owner said to mercury optimax fuel economy so we did. How much equipment and fuel were you carrying?

Hi, Looking for an engine to power my new Avon Adventure 6. Wat really worries me though is the fuel consupmtion, I have read a number of aritcles and threads on the forums about the OptiMax but am still a little unsure. Thanks Chris. Hi Chris Have a look at the thread "Mercury Optimax" a few threads down. They talked about fuse useage there, but i would think 30L to 50L a hour would be the sort of figure you would get.

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. Mercury recommends servicing every hours or annually after the first 20 hours, and the engine has a five-year recreational use warranty. A hull that could handle kg was a good match for the demo Mercury engine and the Stacer Coral Master Sports Runabout planed at incredibly low speeds. It easily lifted out of the hole and the Mercury planed cleanly from trolling revs in 2. The Merc started instantly hot or cold with no oil smoke and, providing the anti-ventilation plate was kept at least three quarters immersed, it was great for backing off estuarine sandbars.

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. The standard in-boat oil tank holds At kg in extralongshaft 25in the Mercury OptiMax outboard motor is much lighter than any of the direct four-stroke competition. I tested one on an Archer 58C plate-alloy cuddy cabin, pushing a total of kg and spinning an 18in pitch Quicksilver Mirage stainless steel prop.

Maybe he needs to have it looked at if it is returning an oil consumption figure of Not looking to replace with a 4 stroke. Click Here to Login. I have been told by the dealer that the Oil consumption will improve after the motor has done 10hours apparently to depending on workload. Tested like no other outboard. Take the etec in to the dealer and get it checked. If you are getting economy like this the rig should really fly at wot. You would have been getting roughly 1. I thought that milage seemed a bit much, but I did a few calculations about the distance up and down monduran and the amount of times I did it over 2 days 7. Al-Ko brake tip.

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.

Fuel pontoons are however one of the last places in Britain where certain forms of piracy is still legal Daniel I have a new mobile it's on charge. If so how much more does the pro xs use? But it will definitely be better than your old EFI motor Also what is the optimal RPM for fuel economy while running in the mid-range? I would calibrate it. Delta 7. On a normal days hunting yellowtail at Dassen Island or Cape Point, chasing birds all over the place, never switching the engines off, i would usually do around nm for the trip. Browse Most Commented. Pushing a total of kg, including two adults, the trolled us at 5. I'm jealous listening to ye talking about your Optis!! Back in calm water at rpm we averaged Running for a long time at rpm does sound like quite a lot of work for the engine, so I'm not surprised you used a load of petrol. Manage Consent. I'm afraid i have no pic's of this trip because i forgot the CF card for the camera but i'm extremely happy with the long-distance cruising ability of top-banana after completing the nm trip back from Poole.
