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.

Mercury optimax fuel economy

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. Once again, in head to head challenges, OptiMax consistently produces top speeds that are not just test proven, but race proven. Superior technology means better efficiency — right across the range. All this means less time at the bowser and more time on the water. Once again, the Truth Is The Proof. At best cruise At a cruising speed of

It gets you in the ballpark. I run my Opti on the Manufacturer recomended Quicksiler Mercury product, would no doubt void my warranty if I didn't.

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.

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.

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.

David Patten Automotive and marine technician. Argh, i recognise the boat profile - that was Friday evening. I think that's a very reasonable fuel consumption for what is a high speed passage. Length: no boat Join Date: Nov Posts: Always a good thing to have plenty of extra fuel onboard!! Visiting St Marys Scilly Isles Hi Dicko the subject is huge will try not to overspeak, what is wrong with the TCW3 spec is lubricity, it's the fact that the minimum standard to pass this test portion is almost, or is artificially low. Your right I can't wait especially with all this nice weather we've been having! Rib tube badges. How do I know which brand of hot air is actually at 20 and which is at 35, each have the same spec!

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. Mercury Optimax series offers motors that come in a lightweight design yet are built with all special configuration features combined with the proven technology to ensure maximum overall performance on the water.

Does the dealer reprogram the motor after 10 hrs to reduce oil consumption? Regards Gary. Can't wait though, Optis are great engines. Optimax fuel economy. Bought a New Rib. Always a good thing to have plenty of extra fuel onboard!! The oil used was about 3lts. HRG Terms of Use. Those first couple of weeks are gonna hurt the wallet. This was acheived with the Dover-Ramsgate leg at a constant knts. My current '02 90 hp looped Merc, carbureted, runs about 3 gallons of fuel for an outing and I primarily go out just to run it as fast as it will go Ned , PM 1. Humber 5. Click Here to Login.
