In my experience Mercury engines typically are built in a manner that makes them more difficult to repair than other brands

Ok Frank let's be honest. Wink. We know that the Chrysler/West Bend engine is probably the most basic, uncluttered, and "down to earth" engine one can use. Since you are the Force/Chrysler/WB guy, your opinion is disqualified. Big Grin It's just not fair. Ha!

I feel the Johnnyrudes and Mercs both have some whistles and bells that take up space and require maintenance.

On the answer to the posting question, Mercury has been making engines for well over 50 years. In recent years they are the undisputed racing champs and have been in the high numbers in racing for over 50 years. They had a Lake X in Florida 40 years ago and the purpose of it was to kill Mercs. Once killed, they would do an autopsy, find the bugs, design them out, and build new engines.

You can't have that kind of track record and be labeled as a junk dealer. Besides Mercs are popular the world over and parts are relatively easy to find on some of these 50+ year old engines.

My 2c,
Mark

Re: Question on reliability and if motors built well to be worked on

But how do we explain the early Optimax's and Fichts. Good motors until they broke, eh? Truth is, if you have to ask the question about ease of maintenance, then you need to take a look at the engine and decide for yourself. Two strokes are two-strokes like they have been for decades. In that era outboards had one, two, three or more carburetors that can get gunked up and need rebuilding. They all have variations of stator type ignition and charging systems that can breed gremlins that make troubleshooting a bit difficult. Lower units are lower units and they either leak water into them, oil out of them, or the water pump fails as well as the gears and shift dogs saying "bye". If you are not mechanically inclined, buy whatever lights your fire and plan on having a service facility do the maintenance. If you are very mechanically inclined and can troubleshoot logically, have a basic understanding of outboard electrics, then it doesn't matter much what you buy. Most 80's and newer carbureted two strokes were pretty bullet proof motors. As is the case with all things mechanical, the care it has had in the past is a major factor in it's current condition and how long it lasts into the future.

I think that the 90's were good years for Mercury and OMC motors. They are all a big PITA to work on. The mercs of the year you're speaking of aren't that bad. The 50's mercs are difficult to work on to me..... :)

Re: Question on reliability and if motors built well to be worked on

Mark: Not counting Force engines which are generally dirt simple, Mercs are more of a PIA to repair than OMC. Some require disassembling the whole front end to service carbs, and getting the gearshift guide off the block on others is almost an exercise in futility. Two of the nuts holding the lower unit are blind and only an open end wrench will remove them. THEN, you still need to drop the lower unit partially in order to fully remove them. I would much rather work on an OMC than a Merc.

Nothing wrong with the engine though: Very powerful and If they were troublesome runners, Merc .would not have sold so many.

So far my only experience with foreign engines is with a Suzuki DF 30. It is a surprisingly strong runner and not too difficult to work on. I had to reset the timing belt. However parts are horribly expensive: 1500 bucks for a factory lower unit. Owner hit some rocks hard, destroyed the lower and the engine skipped timing when it stalled on the hit.

Never really had the pleasure of a Merc but don't they require a number of specialty tools to work on them? Meaning more so than OMC.

I've worked on both OMC and Merc over the yrs. To bad they aren't as simple to work on as the Chrysler/Force. Ah, for the old days.

Ok Frank. Got me confused. What are we talking about here and what does the stripe on the engine cowl have to do with it.

I had 2 Chryslers, 55 2 banger and 85 3 banger. I cannot comment on the ease of repair. They never broke so I never had to touch them. I don't ever remember removing the cowls unless it was at the dealers show room when I bought them. Just gas em and go. Oh well. Wink!

Re: Question on reliability and if motors built well to be worked on

Mark, we are talking about the power. --Ya know--like in cartoons? With the squirrels running a treadmill under the hood?
Chipmunks have a stripe running down their back (actually two) so that was my comparison and allusion to the engine cowl stripe. Should I have used skunk? They have a single stripe.

My God! It loses everything when it needs to be explained!

You've been schooled! LOL
