Stopping the drip
Is there any way of maintaining Vetus stern gear? Mine has just started to leak very slightly after a day’s running and it does not appear to have the conventional arrangement for packing the gland. Will I have to take the boat out of the water?
QFirst make sure the shaft is not bent and that the shaft to engine alignment has not altered. If the engine has dropped on its mounts, the seal may well leak.
Have a look at vetusweb.com/manuals_55.
Awebsite php and select the manual for your actual stern gear; you need to click on the black bold model numbers shown towards the bottom of the images of pages. If you do not know the model number you can get an idea from any of the models with smaller (25+) model numbers.
Vetus describe the maintenance required every so many hours. The one I looked at was every 200
hours with the boat out of the water. This involves removing the seal, cleaning and re-lubricating the shaft. It also shows how you squeeze special grease down a screw hole every so often. It is also possible to replace just the seal part, but to do that the shaft coupling would have to come off and steps taken to protect the seal from any sharp edges and burrs on the shaft when you slide the new seal into position. I have heard of people changing the seal with the boat afloat but I would not be happy to do so the first time.
