Hi,
After talking to lots of people the advice I got was to replace the gearbox with a TMC40. The Hurth HBW50 stopped being made about 10 or 15 years ago and while various companies can supply new or reconditioned Hurth's they generally only recommend that where there is no space to fit the TMC40 which is about 4cm longer and has 5mm more offset between the input shaft and output shaft.
Having explored the darker recesses of the engine compartment I will also replace the engine mounts and the drive plate too. And add a RND flexible coupling. (Are any boat jobs ever limited in scope or do they always add more extra steps?)
Thanks for all the replies,
Conor
Did you ever try changing the gearbox oil?
