I have a 1995 Crestliner Sportfish 1750 with a 135 H.p 3.0L Volvo. It has a rumbling noise/vibration that has gotten a little worse and I think it may be time to replace the gimbal bearing & U-joints. I have owned the boat for 5 years and do not know if/when it has ever been serviced for that. Question is – does anyone know what a reasonable price is to do the job/recommend a good place to take it for this service? I have done much of the maintenance myself and have not been in to any shops for any work yet.
