It was not the original Donzi 350, but with 300 hours after replacement.she should sing (with religious Mobil 1 changes) for another 600 hours before the valve seals start to get tired. Looking forward to retirement and a lot more time on Winnipesaukee next spring.

If the new 350 does not have catalyst exhaust, run Rotella T6 or Delvac 1 instead of Mobil 1 (assuming you want to stay with synthetic). Those oils contain a lot more zinc and phosphorous which are REALLY good for engine longevity. Mobil 1 has to be compatible with modern catalyst engines and cannot contain the same additive packages that diesel oils can contain.
