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, mercury optimax fuel economy.

Mercury optimax fuel economy

This past week I was making a 4 mile run with 3 people and gear and my smartcraft gauges were telling me I was using 2. I am wondering what others have experienced with MPG with their Optimax? Also what is the optimal RPM for fuel economy while running in the mid-range? Are you sure you had it on GPH? You should have been in the gph range which would equate to about 4 mpg give or take depending on your speed. I would expect the best efficiency would be when your just on plan at about 3k rpm and would expect it to be around mpg, for sure nor more than 7 mpg. I also have a on a 20ft Yarcraft and the smart craft gauge. Sure it wasnt on MPG? I was just watching the fuel used screen. I would have a reading at the start of the run of, lets say, 10 gallons and at the end of the 4 mile run I would have a reading of On the 4 mile run it would say I used 2. When I installed the smartcraft gauges, I never did get the speedometer working so I don't think I can get a reading of MPG on the gauges currently. So this reading certainly would not have been GPH.

Bought a New Rib. I just bought a Evanrude Direct Injection 2 Stroke. New posts.

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.

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. Maintaining a clean plane at only rpm is something few four-stroke s could achieve, and the was incredibly fuel efficient at the most economical cruise speed of rpm.

Once on plane, even at Wide Open throttle, I still get a tick about 3 mpg. Last edited by drbrand; at PM. Argonaut I RageGlow. Bound to get even better when it loosens up a bit.

Big tinny's mate The least powerful of a trio of Direct Fuel Injection two-strokes from to hp, the OptiMax produces substantially more torque than its 2. Results 1 to 6 of 6. This also throws out one of the arguments of the added oil cost in the 2 stroke vs 4 stroke debates that often happen. Originally Posted by dockman.

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.

Joined Sep 22, Messages 28, Must of been puffing a bit of smoke out ,mate. There you have three examples of how close that technique really gets. I have one and have no reason to lie about it. The last day we didn't refill so maybe another litres at the most as even though it was a short day it was a rough day. I can take a given tractor and rake hay with it all day very, very light load and barely touch my fuel supply running at rated rpm's. I will have to do some more reading into it. Luckily I got the oil a bit cheaper than that. For a better experience, please enable JavaScript in your browser before proceeding.
