To save starting a new thread i thought i'd jump into this one. Over the last six months or so the forward gear in my Hurth HBW100 (attached to a Vetus 3.10) has been slipping more and more, especially when cold. Once the gearbox is warm it seems fine and reverse is fine, but i'm assuming the "clutch/driveplate" is on it's way out. Having priced up the replacement clutchpack at about £100 i managed to buy a complete reconditioned gearbox for not much more (also previously attached to a Vetus) and it now also matches the colour of the engine
My plan is to swap this over myself and RobinJ's advice above is just what i was after. A couple of questions i do have though is whether it is adviseable to try this whilst in the water and can i push the prop back through the stern gland without having to worry about water ingress? I'm not a complete mechanical fool but any tips would be appreciated.
I'll try and remeber to take some pictures whilst attempting the swap in case anyone is interested.
Roy.
