Bravo Drive oil replacement - What is the factory recommended service interval?
 

This has probably been ,asked but I would like to know after how many hours do your change the drive oil in a Bravo drive?

I bought the boat last season and changed it at 282hrs. It now has about 320hrs on it.

Using Mercury synthetic drive oil. Can anybody post and shed some light here?

50 hours

I thought I read 100 hours (minimum annually) in the manual on drive oil...
