Here's a bump for an older topic - still looking for a reasonably priced nice usable original Y Class if anyone hears of one for sale on their travels or contacts. I also need a Mariner 2 stroke 15hp to suit but needs to be regular gear shift (not incorporated in the tiller) - ex-RNLI would be even better.
Have a pair of ex rnli d class if of interest?? Regards Steve
