Water Pressure Sensor . . .

[tpenfield]

The water pressure sensor on my starboard engine is starting to act up. It starts out reading at 30+ psi when the engines initially start (should be in the 5-7 psi range at low RPM's) and after a while comes down to more believable readings.

So, tomorrow is 'boat maintenance day' . . . I bring beer out to the boat, the Admiral will bring a book.

Anyway, I sourced the part, which I believe is a GM style pressure sensor (50 psi), . . .


.
The mercury branded part (8M6000623 ) is about $165 . . . the generic no-name part is $26 . . .

As far as I know, I got about 8 years out of the Merc branded part. I'll see how the no-name version holds up.

The water pressure sensor has been bated around for years with no clear answer as to which will work. I hope this does the trick will be good to know

I think I'll read a book!

The wetted parts are steel, that's why they fail

I have not put the new sensor in yet, but in our last boat outing the old one started working again.

It looks like the sensor is now reading low, so it will be on the replacement list for the off season.

Our boat outing yesterday got cut short because the toilet broke. It needs a new macerator pump. The pump is a bit pricey, but on its way.
