One is the OptiMax 90 (right), a Direct Fuel Injected two-stroke that is unmatched in its power range, two or four-stroke, for performance and fuel efficiency.
Is Mercury OptiMax 90 a 2-stroke?
90 HP 3-Cylinder DFI 2-Stroke 20″ (L) Outboard Motor. Model number: 90ELPTO.
Is the Mercury OptiMax a 2-stroke?
The Mercury OptiMax range of direct injected two-stroke outboard motors has been a winner. They provide drastically improved fuel efficiency combined with gutsy performance, their noise levels are reasonable and similarly their service costs.
How long will a Mercury OptiMax last?
Most of the Mercury OptiMax motors will have an average life span of upper 900’s to 1300 hours depending upon how well they were maintained. That’s not saying they won’t run past that, but that’s about when we see most of the major issues surfacing.
Is a Mercury OptiMax 90 a 4 stroke? – Related Questions
When did Mercury stop making OptiMax engines?
Optimax was discontinued in 2018 when the new-generation V6 and V8 4-strokes were introduced.
Do you fog a Mercury OptiMax?
Fog the Engine
For direct fuel injected (DFI) two-stroke engines such as Mercury OptiMax models, instead of using fogging oil, squirt one ounce of DFI outboard oil into each cylinder through the spark plug hole. A small oil can with a long flexible neck works well for this task.
How many hours will a Mercury 2-stroke outboard last?
So, with a significant number of caveats, we’ll say that it is typical for a well-maintained Mercury outboard to last for about 3,000 – 4,000 hours of operation.
Is 300 hours a lot for an outboard motor?
Well-maintained inboard engines, inboard outboard engines (unless diesel), and outboards have a serviceable, average life of about 1500 – 2000 hours. If you are looking at a gas-fueled marine engine close to or exceeding 1000 hours, inboard or outboard, proceed with caution.
How long will a Mercury 2-stroke last?
Mercury marine engines – This company is well-known for quality gas-powered 2- and 4-stroke outboard motors that range from 2.5 to 400 HP. Each model can last 2,000 or even 3,000 hours with proper maintenance.
What can you substitute Optimax 2-stroke oil with?
Do you have a substitute for Mercury Optimax 2-Stroke Oil? Our answer: Yes, we most certainly do. AMSOIL HP Marine Synthetic 2-Cycle Injector Oil is a world-class outboard 2-stroke engine oil. We contend that this product is an upgrade over the synthetic-blend Optimax 2-Cycle Oil from Mercury.
Can you use regular 2-stroke oil for and OptiMax?
No. Optimax/DFI oil is for those engines only. Not for regular 2-strokes that require TC-W2 or TC-W3 oil. You can use Mercury Premium or Premium Plus oil in any regular 2-stroke that requires TC-W2 or TC-W3 oil, or in other small engines.
What kind of oil do you use in OptiMax?
OptiMax Synthetic Blend two-stroke engine oil was developed to meet the needs of Mercury OptiMax® and direct fuel-injected (DFI) two-stroke outboard engines.
Should I use synthetic oil in my 2-stroke?
The 2-stroke oil base can be castor, petroleum, semi-synthetic, or synthetic. Modern two-strokes use synthetic oil to avoid high emissions and oily formations on spark plugs. You mix the engine oil with petrol or gasoline at a volumetric fuel-to-oil ratio.
Why you shouldn’t use full synthetic oil?
Risks of Using Synthetic Oil in Older Cars
This is because many synthetic oils contain esters, which are organic compounds mixed with alcohol. This particular combination can be extremely rough on seals within the engine, which can cause the seals to wear down and begin to leak or burn oil.
Can too much oil damage 2 stroke engine?
What happens if the mixing ratios in a 2 stroke engine are incorrect? If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine, blow excessive smoke which is particularly bad for the environment and may (with time) cause the engine to stop operating correctly.
Is there a downside to synthetic oil?
A few disadvantages of synthetic oil to be aware of include: Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.
Does synthetic oil turn to sludge?
Natural petroleum based oil motor oils will break down at high temperatures. At this high temperature oxidation can occur which will develop deposits and varnish. These also can cause sludge. Synthetic oil does not have these problems.
