water pressure gauge question

[Shelbysteve]

Hi guys!

Can anyone tell me which gauge i should go for?

Water Pressure Gauge 30PSI or a 60PSI? I have put a 30psi in my basket at asap, but i thought i'd ask here as i have seen a Phantom with a 60 psi gauge at the last boatshow.

Its for a 89 merc 200 outboard. and i have no idea what pressure the water is. thou it does look as if its a low pressure.

Cheers

Steve.

30 psi will be plenty .
