When I recently bought a “new to me” yacht, it was fitted with a tides marine series one shaft seal. After some work done to rectify shaft alignment issues, the seal developed a leak. The cause was not obvious but the people at Tides Marine were exceptionally helpful. They happily had several phone conversations to help track down the cause and deliver a remedy.
I never felt I was being a nuisance to them even although there was no indication that the fault was due to any manufacturing or design issues. Excellent customer service and technical support.
