Post subject:  Oil Pressure Alarm / Low oil pressure
New 1998 Four Winns 220 Horizon owner - pontoon is gone, kids and dad want to go faster!

My brother has a Bayliner and when he turns on his key the oil pressure alarm screeches untill he starts the engine. However, my 5.7L Volvo Penta Beeps for 1 second and stops. I just want to make sure this is correct operation for the Volvo engine/Four Winns. Should it continue to beep until started?

Also the oil pressure gauge needle runs in the middle during normal operation. However, at engine idle (hot engine) the needle drops way low, just above the red. The oil was just changed at a Four Winns dealer (but by previous owner - I do not know the viscosity). I have been doing some google searches and this sounds common.... Does this sound common / ok? Just do not want to hurt my new baby!

Thanks,
Jeff

Its common. Oil pressure will increase with rpm's. My oil gauges are around 60 when running around 3400 rpm's, but will drop close to 10 when at idle.

It sounds like everything is normal. My 8.1gi does the exact same thing at start up and has the same (surprising) swing in oil pressure from idle to operating range from about 15psi to 60 psi. Not like a car at all.

Enjoy your upgrade. I ran pontoons on Lake Norman last summer, my 264 Funship has been a huge upgrade and a lot more fun. Plus, as you and your son do, we enjoy the mid-50's instead of mid 30's top end.

Perhaps a blower next summer gets me to 60? We'll see.
