cooling water pressure

[Fireisland1]

QSB 380 always 176 Deg. @2,000RPM. I have Borel exhaust alarms but I was wondering if it’s a good idea to have an actual water pressure gauge. I always had them on my outboard and they were a great way of seeing trouble before it’s costly. I am 150 hours on my impeller and will change it out this week. I put a gauge on the 1/4” npt outlet port on the top of my Sherwood pump for testing. I got 4lb at idle and 13lb at 1,800 rpm. I don’t know if these are good #’s or not. I’ll find out when the new impeller is in. Has anyone done this . I’m open to installation suggestions.

I see 6-7 psi at 2300rpm cruise on a Sherwood GC5 pump. Barely registers at idle

N0 on the water pressure–Yes on a actual water flow alarm………………….
