Beneteau 411 prop shaft length.

[Palmask]

Hi there all, haven’t posted for a while but can anyone out there tell me the length of the (30 mm diameter) prop shaft on a 1999 Finot design Beneteau 411. Sorry if it’s a silly question, but I will be replacing mine as it’s showing signs of pitting and it’s chewing the seal. Finding it difficult to get/guess an accurate measurement as it’s still in the boat (with some indeterminate portion obscured within the skeg/stern tube), but will be coming out soon. Am hoping to be able to locate/order a replacement ahead of time before haul out in a few weeks to minimise downtime on the hard. Thanks in advance for any help, advice or pointers.
