Was that a yes or a no?
The cost of the parts may be minimal but if its not trivial to fit then it all mounts up. I agree it might give you warning of a gradual failure, but I suspect the average car driver can't tell you what temperature their car runs at despite the gauge showing them every day, for someone who gets in a boat once a week or maybe less are they really going to spot a gradual drift in a pressure gauge?
I assume you are looking over your shoulder frequently as part of maintaining a good look out.
I'm not saying if its easy to fit its pointless - but the OP is in a 4m Searider with a relatively small engine and limited console space.
