Everyone seems focused on clean oil, but I would submit that's the least of
the things you really need to worry about statistically. Sure, clean oil
will make your engine run longer, but according to Bob Smith, most engine
failures are a result of inattention to the duty cycles of peripherals like
heat exchangers, oil coolers, elbows, mufflers, anti-siphon and transmission
oil coolers. Not replacing a $65 oil cooler before it fails takes a greater
toll statistically than extended oil changes. Not changing impellers before
they fail and not having a downstream strainer for broken impeller parts has
cooked more head gaskets and done more long term damage than using FRAM
filters.
It takes a lot of discipline to log every maintenance activity and build a
history of the real duty cycles for your boat. Things like when to
anticipate an elbow failure, when to change impellers, coolers, heat
exchangers and hoses and making yourself jump into the engine room to do the
work before the component fails.
