Alternative Method/Materials for Analog AND Digital Water Pressure (V6/V8 Models)
For 20" Models already rigged with Analog Water Pressure (Gray Tubing), here's a simple method and Parts List to install Digital Water Pressure.
Yes, there are other ways- and these parts vary from the "official" listed Block Pressure Sensor for this engine model.

Just saw this post, would this setup work for my 2025 175 Pro XS (s/n 3B459479) alreadyOriginally Posted by EuropeanAM
have the analog water pressure setup installed but I also have the SC1000 smart craft gauges and want the digital water pressure also! Can I use the same digital sensor in the image or get one that fits my motor and still use the other fittings listed?
Yes- this would also work for the V6 4-stroke models.

Thanks Don! Got Rhonda getting my parts order ready!
In your opinion Don why would one want a analog gauge when the digital gauge can be so much more accurate when linked to your Merc monitor? I like the set up it is clean and simple
I'm one of those guys who wanted analog gauges even though my current boat was outfitted with a Systems Monitor (SM). The SM was mounted in a terrible location, 90° to my right just forward of the throttle control and to read it, I had to turn right and bend down to see the small display. The analog gauges were in my line of sight in the panel.In your opinion Don why would one want a analog gauge when the digital gauge can be so much more accurate when linked to your Merc monitor?

When I learned about the Mercmonitor (before I found BBC) and what it could do, I decided then and there the SM was history and so was my analog tach. It made an "analog gauge guy" a believer and once I crossed over, there was no going back.
Fellow BBC members benefited from my upgrade (sold the tach and SM here) so I was happy and those who bought them were too.

I am old school and also went with the analog water pressure and hour meter gauges. They were much more reasonable in price and serve the purpose for what I am doing. To each his own.In your opinion Don why would one want a analog gauge when the digital gauge can be so much more accurate when linked to your Merc monitor? I like the set up it is clean and simple
one of each, very clean rigging !
Personally, I would just go with digital. However, since many boats already have an analog Water Pressure gauge (or some folks like having it right there and don't want to replace all their analog gauges during a repower), this is a simple alternative.

Clean! Thanks for sharing!
don, would these parts also work in the 25” models?For 20" Models already rigged with Analog Water Pressure (Gray Tubing), here's a simple method and Parts List to install Digital Water Pressure.

Yes. If the engine is not equipped with an Analog Block Pressure Kit, one would also be needed.

Thanks Don, I’ll get with Rhonda when I pick up the new mercury pro xs 250 4 stroke in two weeks!
Is it intuitive once receiving the parts and looking at the picture or is there supposed to be a written description of the modification here as well? I only see the picture with the referenced parts?
Really straightforward- you're installing the "tee" in the existing GRAY tubing, which you can usually shorten by a couple inches (giving you the piece you need to go up to the sensor, which simply plugs into the wiring provided on the engine).
Remove the dust cap from the wiring connector, plug the sensor in. A couple tie-wraps to hold things in place are advised (and it should look essentially like the picture).

Well there’s nothing obvious looking at my motor, heck I can’t even find the grey tubing lol. I think I will just let you all do it when you do my 20 hr service here in a few weeks.
My motor will be a 25” model.What sensor.i assume digital to go with sc1000 or mercmonitor?
Correct. See Rhonda's post (pinned at the top of the Forum) - if you drop her an email she can set you up.
