3270 Motor yacht buzzing noise-gctid814969

[Guest]

Good Morning,

I'm looking for some help with a noise problem I have on my boat. The boat starts fine. Runs without the buzzing for approximately 20 minutes. Then a loud buzzing starts. The buzzing will last for about 10 minutes. Then it'll stop and start again in about 10 minutes. All the gauges look fine. The boat only stalled once when it was buzzing. I know it must be some warning buzzer but I don't know where to look.

What motors do you have? If they're Hino's, that would be the oil pressure buzzer. did this start after you changed the oil filter?

Hi,

Yes it did. And they are Hino motors.

You may have installed one or both filters upside down if they are the element type. Easy to do. The small hole of the filter is the top. Hope that helps.

Thank you for the quick response. I'll have that checked.
