Mercury Optimax Outboard Review: Are They Good And Reliable?

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.

That raises the most obvious question: are Mercury Optimax motors good enough?

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.

Let’s learn more about the actual worth of the Mercury Optimax Outboard motor series from today’s article-

Here’s How Good the Mercury Optimax Are:

With over decades of reliability, Mercury has introduced the Optimax series. Along with all the basic features, these motors are equipped with Low-pressure Direct Fuel Injection (DFI), corrosion-resistant alloys and finishes, rugged components, Custom exhaust tuners, and high-performance cylinder heads to deliver excellent hole-shot acceleration, increased top speed, better fuel efficiency, and smooth overall performances.

How Durable & Reliable Are The Mercury Optimax? 

Mercury is known for its decades of innovation and leadership reinforcement.

Not only that, but Mercury Marine also has established its name as a trusted source for offering tough-built outboard motors which deliver legendary performance and their Optimax series is no exception either.

Mercury Optimax outboard motors are specially considered trusted because of their two-stage direct injection system. These uniquely shaped pistons and precise fuel injection provide more complete combustion for outstanding fuel economy and smoke-free emissions.

The Optimax series offer motors that not only feature the most complete atomization of the fuel for more power, enhanced fuel efficiency, and lower emissions, but these outboard motors also come equipped with Custom exhaust tuners and high-performance cylinder heads for ensuring maximized power, torque, and performance.

As a result, you will get spectacular acceleration and top speed while riding your boat over shallow water.

Besides ensuring outstanding top power and speed, Optimax motors also have a great reputation for being small lightweight yet powerful enough to beat the larger platforms.

No other similar graded outboard can offer such a lightweight design equipped with top speed as the Mercury Optimax series offer.

Even every Optimax motors are capable of delivering lightning-fast throttle response, which ensures fuel savings, low noise or vibration, and emissions along with legendary reliability.

Mercury Marine always has a trusted reputation for being at the forefront of corrosion protection and the Optimax series also maintains the same. Every Optimax outboard ensures deeper R&D capabilities and uses better alloys, superior paints, torturous testing for offering the toughest body to dominate in the saltwater.

How Long Do The Mercury Optimax Last Compare To Similar Brands?  

Mostly Optimax motors can run smoothly from 70k up to 240k without any major issues, but some engines might go up to 330k.

Reportedly, most Mercury Optimax motors come with an average lifespan of at least 900 up to 1300 hours, but it mainly varies depending on how well you are taking care of its regular maintenance.

What Are Typical Troubleshooting Issues With The Mercury Optimax? 

According to several consumers reports, a few common troubleshooting problems might occasionally arise or appear. Such as the engine might struggle or refuse to start, engine idling issues, sudden loss of RPM or power, fuel system failure or leaking, and engine overheating problems.

Besides that, some Optimax 225 outboard motor users claimed that they sometimes experienced shifting difficulty.

Even a group of Optimax 150 owners have complained about encountering electrical connection or wiring issues, and sometimes the alarms went off without any visible problem. Some claimed to periodically notice engine stalling during cold start and trouble with water pressure.

Based on several Optimax 200 owners’ experiences the engine tends to get obnoxiously noisy and irritating, especially at lower RPMs. Other common problems such as Air Compressor Failure, Wrist Pin Bearing Failure, and the lower unit blowing up might also occur with the Optimax 200.

Let me also remind you that none of the above-mentioned troubleshooting problems are not particularly happening with only the Optimax series. Mainly those are the most common problem that occasionally occurs with any outboard.

Are The Mercury Optimax Still Being Made?  

Unfortunately, Mercury Marine discontinued making Optimax outboards in 2018 and instead of Optimax production, Mercury came up with the new-generation V6 and V8 4-strokes around that time.

Does Mercury Still Make Parts For Mercury Optimax? 

Since Mercury no longer produces one of the most popular outboard motor series Optimax, the company is no longer making the spare or replacement parts and accessories for the Optimax series.

But dealers and aftermarket parts & accessories manufacturers might still be producing them since some of the Optimax outboards are still available on the market.

Where Is The Manufacturing Location Of The Mercury Optimax?  

Mercury Marine has several manufacturing facilities located in different countries to fulfill the high consumer demand and the company has two manufacturing plants located in the USA (Wisconsin & Florida).

Besides those two, Mercury also has manufacturing facilities located in Mexico (Juárez), Japan (Komagane, TMC joint venture), China (Suzhou), and Belgium (Petit-Rechain).

Also ensuring 100% perfection after manufacturing each of the outboards, Mercury also verifies their final testing from its different testing plants. These testing plants are located in Florida (Panama City), Wisconsin (Oshkosh & Fond du Lac).

However, the company has not disclosed exactly from which manufacturing location, the Optimax series of outboards are manufactured.

Which Brands Can Be The Best Alternative To The Mercury Optimax?   

Since Mercury has discontinued manufacturing the Optimax series of outboard motors and has no intention of starting the Optimax series production again in near future, it is obvious to look for better alternative choices.

In that case, one can consider outboard motors from some of the top manufacturers such as Evinrude, Yamaha, Suzuki Marine, Honda, or Tohatsu Brands.

Customer Reviews On The Mercury Optimax: 

While I was going through several consumer forums, review articles, blogs, vlogs, and other online portals where consumers leave their ratings and feedback, I figured that most of the Optimax users or owners have given good ratings and expressed their satisfaction after using the Optimax series motors on their vehicle.

The majority of any Optimax motor model users rated their owned Optimax model 4 out of 5, no matter whether it’s the 75 HP, 115 HP, or 225 HP option.

Here I have highlighted some of the Mercury Optimax Outboard motor owner’s feedback for your better understanding-

” I have a Haines patriot with a 225hp Optimax and she really get the boat moving and excellent low down and amazing top end torque. I love Merc’s and they are now dominating the 4-stroke market. In a few years I will repower to 4 stroke 250hp Pro XS. Catch me if you can :).”

– Michael A.

“Bought new starts first time, no smoke, Tops mind blowing on speed & fuel .Very quiet gear change and at idle, easy use. The price was cheap & so is the service cost. I was unsure before I bought for I love Johnson, but now I love OptiMax 75hp [censored word removed] it is fast and I love it 5star plus.
PS. Go for It I’m glad I did
Reliable Tops on fuel fast v fast
Warranty too short 5 years free service would be nice “

– Bigphil from Hunter Region, NSW.

However, just like any other outboard motor brands, these series from the Mercury Marine also come with a fair share of limitations.

Unfortunately, that is why I also found out several angry and highly disappointed customers who complained about their motor and shared what trouble they went through due to their Optimax.

” We bought a boat with a 2012 mercury 2 stroke 75hp engine, and it has been the biggest waste of money. At 40hr the ignition timing magnet developed fault and had to be c ok completely stripped down to replace, the service centre took 4 weekend diagnose the problem, at 200 hrs the engine has to be overhauled due to ignition problems. At 380hrs th magnets in the flywheel fell of stripping the gears of the starter motor pinion. Changed the flywheel and starter at $1600. At 430hrs the engine ceased and do not want to crank today. Mercury is the biggest piece of black crap ever. I won’t buy any mercury anymore despite all the rubbish advertising that it is a good motor. I suggest that people focus on other brand before scraping at the very bottom of the list of Mercury. “
