Hello. We have one leaking hydraulic cylinder on our boat. We have researched and realized that Volvo does not sell a seal repair or rebuild kit for these cylinders, but we have seen where the OMC seal kit has been used successfully instead. The problem is that I found 2 part numbers and not sure which one we need to get. There is 3854247 and 0985060. Can anyone advise on which would be the correct kit? Thanks!
