In May 2018, Mercury Marine discontinued manufacturing all of its 2-stroke engines, commonly called the OptiMax series.
Are OptiMax engines 2 stroke?
Low-pressure Direct Fuel Injection (DFI) delivery, corrosion-resistant alloys and finishes, and rugged components keep Mercury OptiMax outboards on the water, season upon season. Two Stroke Direct Injection. 505 Lbs (lightest model) 20, 25 or 30 inch models.

Is an OptiMax a good motor?
The Mercury Marine OptiMax 150 is the middle of three direct fuel-injection two-stroke outboards from 135 to 175hp, all of which use the same 60° V6 powerhead. The 2.5lt loop-charged powerhead has been around a long, long time and in my opinion is one of the best Mercury engines.
What is the difference between Mercury EFI and OptiMax?
The Optimax is a direct injected motor which used a computer to a just the fuel going into the motor giving you the best possible burn, fewer emission and better performance. The EFI motors are reliable but put out a lot more emission and are on they way out.
How does the Mercury OptiMax work?
Originally developed by Mercury and the Orbital Engine Corp., OptiMax uses a belt-driven compressor to deliver pressurized air and fuel to each direct-injector nozzle at the top of each cylinder. As a result, OptiMax engines use up to 50 percent less oil and run virtually smoke-free.
What year did OptiMax come out?
1995
Introduced in 1995, Mercury’s OptiMax direct fuel-injection system was a lead bull in the manufacturers’ stampede toward cleaner two-stroke engines.
How many hours are OptiMax good for?
Some go out at 70k, some at 330k, but in general, you should expect 240k out of them. Most with I/O or inboards figure at least 2500 hours before a rebuild. I’ve seen a lot of them with 3500 – 4000 hours.
