Masterlock Outboard Motor Lock that was fitted on the thumb screws of my 9.9 mariner outboard for around 6 months and stored under cover and still looking like new. I have the bill of sale "for insurance proof" + both keys - and ready for use. Selling for less than half price (along with other boat/fishing items = i am selling due to ill health) Collection from Selston Notts (2 mile from M1 - J27) or I could post for £4.95 after payment sorted. Contact me on here if i can help further in any way. Regards Alan.
