Have been having a problem with the ‘R & D’ coupling bolts. Fitted as standard with our Beta 38 engine and PRM 120 gearbox. It was back in August when Vic noticed that a few nuts had come off !! We were changing the engine oil at the time and put the nuts back on. Thought no more about it, silly, till the drive got all noisy and ‘fell apart’ in November. Thankfully Sue & Vic on ‘No Problem’ pulled me out of the bottom lock at Wilton. Got some more nuts and bolts at Wilton Marina and put the coupling back together. I have to tighten them after a long run now.
