I have gotten a lot of great tech info from these forums. I have the 88 xr4 150 running excellent. How ever these dam beep beep beep oil alarms and now the solid beep are pissing me off. I have a oil pressure gauge that reads 8 to ten psi at idle and 25 or higher at running rpm so I'm not worried about the alarm. I can watch the gauge. Also just replaced the water pump and t-stats and it spitting water pretty good and temp gauge works and it's running cool. I bled the motor tank of air didn't stop it! Is there a way to disconnect these alarms in one shot?

Re: Merc xr4 150 warning alarms.

Your water pressure would seem to be inaccurate. Most V6 motors have no more than 15PSI at cruise.
