Westerbeke Engine Mount Part Numbers


40510 for the front

40511 for the rear. They are virtually the same spec other than the rears are designed for a bit more weight.  This is for the Westerbeke 42b four with a Hurth transmission.

Westerbeke’s original part number for the 42b is 36341 however Catalina had different mounts spec’d for this motor in our boats. I managed to get a pn off one of the original ones and dealt with the wb dealer here in Ontario.  The 40510/40511 were originally used on the 35b Westerbeke.

Westerbeke shows no stock if you plug the number in on WB main website but according to my guy they have 25 currently in stock and it is a stocked item.

I decided to stay with OEM parts as they lasted this long and easier to swap out with the same re measurements height etc. About $180 piece
