Oil pressure on 2004 Nautique 210 team edition???

[jbg]

Took the boat out for a run today ( motor 330hp) and after a couple of wakeboards the alarm went of continusley until we turned it off. Startd back up and had no issue until we were around 3000 rpm and the alarm just bipped onced. Turned boat off and on and the boat flashes red and says low on the tacho? When starting the boat it has approx 40 psi but only goes to 50 psi under load. Is this fine or what is the recommended oil pressure?. Checked dipstick and oil looks fine. Also went through the mode button and it says P 01 psi? Any suggestions.

Thanks

My mistake, I think it might be the batteries as this was the first time we have taken the naut out for quiet some time.. The stereo was dropping out ( like the CD was skipping) the battery one said 11 volts and battery two said 12 volts. Might charge them up and see how we go..
I also read my book and P 00 PSI is my oil pressure ( hello d***head)..
