We have a significant vibration around 2500 rpm
in the Volvo
D2 50hp in our 2022 FP Astrea 42 with ~ 100hrs.
I took delivery
of the boat
late March 2022 and about half way through the 1200nm delivery
, the vibration developed. We backed the speed down and vibration calmed-down.
Both engines have had their initial service
(with mounts checked), yet the vibration continues.
Sorry, but searches yielded no hits on my topic.
Any thoughts ?
