Yanmar 44 JHE Service Interval

[rodtremblay85]

Hi Folks,

Bayfield 36 Located Lunenburg NS. My service interval per the manual is 150 hrs (Factory Yanmar 44 JHE, 2200 hrs ) I have a couple of questions. Engine was fully serviced May 2021 and has had about 75 hrs put on since that time, stored over winter:

1). The manual recommends draining fuel tank annually before storage. This seems backwards to what I have always done (fill tank) am I correct?

2). Annual service. Do most folks change oil with a warm engine after layup? What about filters if you haven't reached 150? Same for fuel filters?

3). In the operating instructions, yanmar recommends a procedure of draining water from the block after each use, or before storage. I have never heard of this practice, sounds immensely cumbersome. Any thoughts?

Thanks in Advance

Rod
