Low Oil Pressure Alarms

[Lucky1]

I have a 94 Bayliner. The oil pressure is fine at high speeds but at idle it drops to 10 or below and the alarms go off. The boat shop replaced the sending unit which helped somewhat but the problem still exists. Any ideas or is this serious? Thanks

Give it an oil change and use a decent oil.

Thanks. I tried that and used a 40 wt oil. It helped but the alarms still go off after about 30 min. of running around and then dropping down to idle.
