Are "commercial" engines better?

Post by Ixneigh »

Rather then hijack a thread about fourstroke choices I'll post a new thread.
In a YouTube video there are two guys backing some kind of barge or something until the twin etecs where underwater :cry:
First, are they really that waterproof?
Second I noticed that every engine manufacturer seems to have a commercial version of the engines they sell to consumers. It it really better? More rugged? If so why don't the Mac crowd talk more about them or recommend them?
I'm not fishing for a living but I want the same engine that the guy who has to run his boat e ery day or else he goes broke, has.

$$$$$$$$$$$$$$$$ Maybe we just don't use our motors enough to justify the additional cost?

While I don't know anything about commercial engines, it may be possible that they're less complex rather than more. Firstly, an engine that is expected to be run daily does not need any mechanical components designed to lay the engine up for extended periods (such as the ETEC fogging mechanism for example, oil scrapers, cold-start motors, high-output alternators, etc.) and may use less costly consumables such as filters and gaskets that are intended to be replaced more frequently. Lower output alternators can be used since the battery will always be topped off and isn't expected to retain a charge for six months.

Reducing the complexity and grade of equipment lowers the price, which makes them more competitive for fleet purchases.

Not saying that's how it is or that there's any mechanical difference at all, just pointing out that is possible the differences are not positive.

Notice they did not back up with enough speed to let water into the top of the engine air intake cowling--the out come might have been different otherwise.

That's a very good question. I would expect that the specific differences in the package (fewer "frills") would vary from manufacturer to manufacturer, but would generally say that the warrantee period for "commercial" products is shorter.

never owned a commercial motor, but have had many motors, to me, no, the ones that are made for the general public work fine.
I have one 15hp Chrysler that's 35 years old still going strong, another I just took off my whaler that's 25 years old same thing.
I can understand this question if someone had loads of problems with their motor, and thought a commercial motor might be better.

Is that the case for you?

normally a more robust gear case. SS wp liners, harden crank, better seals on the cover, etc... basically a rough duty engine designed for abuse, and geared for mid to low rpms. and not cheaper.

I would not say that commercial ones are better because they are nothing really more than just a branded option when compared to other engines.

Though in many times than one, the brand work as something like a guarantee to prove that they hold some greater value to it.

But then again, most people just go with the branded ones just to be sure about what they are getting.
