Mariner 2005 Transom Clamp Thumb Screw Assembly

[tonybbb]

Both the thumb screw assembly's on my colleges Mariner 50 HP 3 cly 2005 have seized up so rather than force them we have cut them off and drilled down to the core diameter of the bolt. I am not sure what thread is on these it could be a 5/8 UNF either 16 or 18 TPI or a M16 fine can any one tell me

Thanks in advance for any help as it would be much appreciated

Best Regards

Tony

Hi I have since found out that the Thread on these bolts are a M16 x 1.5mm (metric Fine thread) so all sorted made a couple of new bolts andevery thing is good

Thanks
