Anybody know of a good source where I can find a water pressure gauge kit for my 71 merc 65hp 4cyl outboard? I know theres lots of them out there in catalogs etc but Im not sure about application for my particular engine. Thanks
All about the same. Guage in dash, small tube to engine. You need somewhere to attach tube to water system. Usually a plug near the thermostat, or you can put a "t" into a waterline.
