I have decided to do my own maintenance this year. The owner’s manual mentions two fuel filters, one low pressure and one high pressure. It says changing the high pressure filter requires a special tool and procedure and should only be done by an authorized Mercury dealer. This one is supposed to be replaced at 300 hrs. I was wondering if it is really necessary to have it replaced only by an authorized Mercury mechanic. I was also wondering if anyone out there replaces these filters themselves and how often do they usually get replaced?

What is a Veridito?

Sorry about the mispell. A Veradito I understand to be a term coined by our website moderator to be the Mercury fourstroke EFI 75/90/115 line up which are essentially the same as the Verados except without the supercharger. They are smaller versions of the Verados, hence, Veraditos.

Anyway, it is the engine (Mercury 90 fourstroke EFI) that BW put on my 2007 170 Montauk.

The term "Veradito" is in common usage here in order to disambiguate the particular model of Mercury motor being discussed after Mercury gave the motor the same model name as the two previous motors, all of quite different design. This bizarre situation has forced many names to be invented for the motors. Boston Whaler, for example, invented the term "L4NA" to describe these motors. I invented the term "Veradito." Mercury just calls them FOURSTROKE models, which is precisely what they called two earlier motors of the same horsepower.

"Veradito" comes about due to the Latin sound of the name Verado, and is a diminutive form using the rules of Spanish. This a perfect analogy to the motors themselves, as these motors use the same general engine block arrangement, same displacement, and likely share many common components with the Verado motors, yet they are lower-power, non-supercharged models.

Some people who are extraordinarily fond of Mercury outboard motors seem to take an irrational dislike of the term, a behavior for which I have never been able to find a good reason. Veradito seems like a perfectly suitable name. I have even seen it used in major boating magazines to describe these motors.

Since Mercury failed to give these motors any sort of distinguishing model name, Veradito is as good as any, and much preferred to having to post long explanations about exactly which 90-HP FOURSTROKE motor you'd like to discuss. But, if you don't like it, just make a new name of your own. Too bad Mercury didn't.

I hate to bring this up, but you cannot really describe a Mercury motor as being a "2007" motor. Mercury has dropped the use of model year designations for their motors as far as the retail customer is concerned. They have replaced the model year designator with a new designation, "product year." The product year designation is used for compliance with government regulations, but, unfortunately, the product year designator is often not clearly presented to retail customers. As far as retail customers are to believe, Mercury outboard motors do not change in model year increments, and one VERADITO is the same as another.

Well, I actually like the name "Veradito" so I am all for it. For those who have been following postings on this site, the name will let people know exactly what engine I am referring to. (I have actually seen it used on thehulltruth.com) Also, I took 4 years of spanish in school and happen to like spanish words. It also seems to elevate the status of my otherwise unassuming 90 hp engine, so in that respect, Mercury may be overlooking a marketing angle.

Besides all of that, does anyone replace these fuel filters (particularly the high pressure filter) themselves as part of their regular maintenance practices?
