You're worrying me now: only done mine once in 12000 hours. At least, having a dry exhaust I can watch the engine water outlet and as soon as it projects less than three feet I know there is a problem.

1 at 400 hrs as a precaution as new to me
2 at 2500 hrs after a number of Rhine trips
3 at 5000 hrs as slack felt in one shaft, it rocked in the cam plane. did the other one to keep them even.

Thanks David and all for advice. I got the pump apart and found a lot of corrosion where the oil seal should sit. This part was not renewed when I replaced the engine and so I would imagine might be original from 1984 with the old engine (which had done an unknown number of hours but certainly more than 3000) . I have no idea where the corrosion has come from but won’t risk it so i am replacing the whole pump with a new one from Lancing.
