I have recently purchased a 98 Sugar Sand Tango with the Mercury 175.
While test driving the boat there was no warining buzzer, but on my
first time out I noticed an intermitten warining buzzer.

The buzzer was sounding when I started the boat, but went away when I
got underway. While moving, the buzzer would sound if I would cruise
at the same speed for a while (about 5 mins or more), but go away if I
increased or decreased speed. I have been researching this and I
think it might be related to oil injection? Having just purchased
this boat, I am not sure what the warining buzzers mean.

I plan on pre-mixing some gas for this weekend, and then getting it
checked out. Am I crazy?


Any suggestions?

Thanks,
