  • ox66 1999 200hp goes to safe mode

    I have a 1999 ox66 200hp engine. I have 2 issues they could be related.
    When I turn the key switch on the horn beeps for 10 -15 seconds then goes off. the center oil bar on the tack both blink. The bar to the left stays on but the middle one blinks. I have twin engines that I bought used with the boat. This is a issue with both tacks. When the boat is run at 4000 for 20 minutes the starboard goes to safe mode and the horn sounds. If I turn the motor off and then right back on it clears and I can run for another 20 minutes. The port engine does not have the safe mode issue but does have blinking center bar. I have checked and confirmed that both engine oil tank and remote tanks are full. Any ideas?

    if rigged correctly twin yamahas will self test the horn.
    the tachs also self test.

    the running issue.
    when the engines go into safe mode what do the tachs display???
