Re: [Amel Yacht Owners] Kent-vetus coupling

Hi Eric, here are some pictures from the VETUS coupling, 35mm, as it is modified/machined from AMEL. Note that the aluminum is machined in order to enter the gear-box output shaft flange. Note that the steel part is machined at the front end, in order not to be "caught" at the C-drive input shaft's bevel end. Of course, there is absolutely no hole to drill or thorn screw to install between the steel hub and the C-drive shaft. Good luck.

That is why they specify drilling a hole in the drive shaft and installing the roll pin. (They used to use a set screw, which could easily slip and you could loose the shaft right out the back of the boat - ask me how I know.) On our Amels there is no force pushing or pulling the shaft and the pin is absolutely not needed, thus Steve's choice is totally correct. The key transfers the rotational force from the engine drive shaft to the "C" drive input shaft and is all that is needed. Craig, SN68 Sangaris

However, on the Vetus instructions, they say you must drill through the shaft, and use a provided roll pin. We chose not to compromise the shaft by drilling, and just used the keyway which seemed identical to the old broken coupling. Steve Aloha SM72 On Jan 9, 2017, at 02:08, Kent Robertson karkauai@...
