Looking at getting a larger boat. Most of the boats I am looking at have inboard engines either gas or diesel. I am leaning more toward the diesel. I am wondering what kind of yearly maintenance besides oil and filter changes need to be done of these types of engines to keep them in good running condition? Also I fish out of Cypremort Point so I am also curious if anyone knows anyone around the area that services these engines especially the diesel engines. Yanmar is the name brand of the diesel engines that I am looking at. Any opinions are welcome I would like to know all the pro's and cons about this.
