1992 Evinrude 175-HP

I found an 1992 Evinrude 175-HP that says it is an "OIS Optical Ignition System 2000". It has a faded black color, maybe just a charcoal gray that is not faded. "V6 Loop Charged" is stamped on the back of the block on a plastic cover.
It was hard to see the model number but my best guess was a E175QLEND when I looked at it, but a Q doesn't decode as a V6.
I found that it weighs 370-lbs and a decode says it is a 1992 regular rotation.
I need a 25-inch, not a 20-inch.
I have a 1994 140-HP V4 loop charged 25 inch. Will that lower end exchange onto the 1992 175?
Does this engine with the OIS 2000 ignition system have a good or bad reputation for reliability?
There is a second matching counter rotating 175 available, but it has some "unknown issues." They are being sold together and one is supposed to be in very good working condition. They come with matching stainless VIPER propellers, which are in excellent condition. They were used by a fire department on a Outrage 24 or OUtrage 25 boat, and were changed out for Honda engines a couple of years ago. They would likely have seen very low hours and were also dealer serviced at the local Boston Whaler store, which also was Evinrude dealer.
Thanks for any help.

The engine is definitely a V6. Not positive, but I believe the gearcase on V4 is smaller than the V6 gearcase. They are good running engines but thirsty compared to modern engines.
I have a 150 Johnson Oceanrunner counter-rotating engine available in two to three with 250 original hours. It is the same engine as the 175. In Connecticut, runs flawlessly, can be demonstrated with a deposit. A 14.5 x 19 stainless propeller included. $1500, pick-up only.

Thanks, these two are a half-hour from my house and they are asking $1,500 for both.
Most interested in anyone's experience with this outboard; was it reliable?
I know they are noisy and harder on fuel than a new 150 E-TEC for say $15,000, but as that old saying goes, you can buy a lot of fuel for the price difference.

I believe that engine is the 60-degree 2.6-liter block. The basic engine block, midsection, and gear case all are very reliable and time-proven designs. It is a carburetor engine. The only variant from earlier models is the ignition timing system, which uses some sort of opto-electrical devices. I believe that makes it a bit trickier to work on, as some special service tool or rig is required for that electronic system.
I believe the gray colors were a standard color available then.

If it is indeed a 1992 175-HP, [then] it has those terrible plastic carburetors, plastic vapor separator, plastic fuel manifolds, etc., that shrink and warp with age. Pretty much the whole fuel delivery system is plastic.
A 23-year-old plastic in a marine environment is a recipe for disaster. Expect to spend lots to get them back into safe, non-fuel-leaking, condition. I had a year 2000 150-HP Johnson which is virtually the same engine. The actual blocks are well madem but the extensive use of plastic throughout the fuel system was a major mistake.
The E-TEC's use [half] the fuel of those old carburetor V6 engines.
Do yourself a favor: take a look at the parts pricing of just the fuel system components before you invest in that engine.

I believe the material being called "plastic" (as a pejorative term) is actually a nylon-reinforced polymer called MinLon. Carburetors made from that material have been used in Evinrude engines for several decades. I am fairly certain that the six carburetors on my 1992 Evinrude 225-HP engine were made of this material, and there were never any problems with them.
As far as "plastic" as a material goes, I suppose one could say the same sort of things about a Boston Whaler boat, which, after all, is also made of plastic (as defined by Whaler_bob).
Actually, on my 1992 Evinrude engine with "plastic" parts, most of the problems I had to resolve were electrical, including the spark ignition system. My engine had an older design, but the engine under discussion has an updated design, the OIS Optical Ignition System 2000.

For help with Evinrude model numbers up to 2005, see
According to the guide, a 1992 175-HP engine would have a model number that begins 175GLEN. Perhaps you misread the "G" as a "Q".
The "G" denotes "special styling" and may account for the gray color.

The fuel pump in the engine under discussion is a fuel and oil mixing pump. This component is often called a VRO pump, or more accurately an OMS (oil mixing system) pump. It is described in detail in an article published here at
Myths and legends about the VRO pump abound, as you will find by reading the authoritative article linked above. The housing of the pump is the same sort of "plastic" that Whaler_bob has warned us to avoid.
Considering the age of the 1992 engine, now 23-years-old, and considering the tendency of gasoline fuel today to contain ethanol, sometimes in concentrations far exceeding the usual 10-percent, if the engine you are considering is still running with its original 1992 fuel pump, then it would be prudent to replace that component.
When I sold my 1992 Evinrude in 2009, it was still working perfectly with the 1992 fuel pump, but I told the buyer that it was my intention, had I kept the engine myself, to replace the fuel pump in the near future. I advised the buyer that he should consider replacement of the fuel pump as a preventative maintenance measure. As it turned out, the buyer did not replace the fuel pump when he bought my engine, but, about a or two year later, the original fuel pump began to exhibit problems and was replaced.
Having problems with the fuel system of an outboard engine due to the presence of ethanol in the gasoline fuels we use today is not limited to older engines made by Evinrude. It has been widely recognized that the Mercury VERADO fuel system has suffered damage to components due to ethanol-gasoline fuels, and Mercury has had to replace--often under warranty--components in the fuel systems of their engines at just a few years of age. Whether or not those components were made of "plastic" as defined by Whaler_bob, I cannot say for certain. But it should not be inferred that there is any special risk incurred if a fuel system component is not made of metal. Usually fuel systems are mostly made of rubber hoses.

Thansk for the replies, not sure at this point what I need to do. I'm surprised the 4 cyl and the 6 cyl weigh almost the same.

The 2.0 liter V4 looper 140hp shares very little in common with the 2.6 liter looper.
The 2.0 liter V4, 3.0 liter V6 and 4.0 liter V8 are extremely similar with more cylinders added to the basic design.
The 2.6 liter 135hp, 150hp and 175hp are a different beast.
