Hey Tom, when using a hot tub pressure switch for a hour meter you said use one with a micro switch. Why? just to keep the size down or is there another reason?

Size. I believe they activate at 1.5-2 psi. My boats at idle water pressure is only about 5 psi. This is typical idle pressure. I just got low psi for this reason.

Thanks, I see some of them are adjustable 1-5 lbs.

That should work good.

Make sure the contact is a make contact.
