I want to connect a water temperature gauche and a pressure pressure gauche on my outboard yamaha. Can anyone tell me the the normal temperature and pressure?
Thanks

Carlos,
I can tell you what is normal for my 2000 C115, which is also the same V-4 block your 130 is.
My temp gauge reads approx 130 degrees f. - it is a Teleflex (I believe, it has been so long since I installed it). The thermostat is designed to start opening at approx 130 and should be fully open at 140 f.
The water pressure gauge (I'm gonna guess on this since I don't have one) should read from ten pounds at idle to 18 psi wide open throttle. The pressure relief valve is designed to open at 20 psi.
Good luck [img]smile.gif[/img] ,
