Oil alarm merc. 60 hp efi 2006

My alarm goes of at 6300 rpm saying beep, beep beep beep when i pull back the throttle a little bit to 6200 rpm the alarm stoped again and the engine goes perfect going back to 6300 rpm it starts again. i know it is the Oil lever alarm but the oil stand is ok - any suggestions ?

you could try cleaning the sensor and looking for corrosion or bare wire around it - in the end it could be the sensor or the injector itself not delivering oil fast enough at speed - dont ignore it though it will burn up quick .

Your RPMs are too high that motor is rated for 6000 max.

You need a higher pitch prop at least 1" more maybe 2". If you are currently using a 12 pitch prop try a 13 or 14. Going to a higher pitch will decrease your RPMs and give you more top end speed but you will lose some hole shot. Ideally you want your RPMs at the top end of the recommended range (5500 to 6000 RPMs for a Merc 60 4st). See the props forum for more info.

I have the same engine on a 2006 Lund 1660 Classic side console (860 lbs dry weight). I run a 14 pitch prop at 5900 RPMs at wide open throttle (WOT), trimmed out, with a top speed of 35 MPH on GPS with a moderate load. With a very light load I have hit 38 MPH on GPS.

Until you find the right pitch prop try and keep your RPMs below 6000. Hope this helps.
