I am not aware of anywhere that Merc has ever listed the size of their fasteners - of course, you can find the "merc part numbers" and buy them from them - but as far as stating say a 1 1/4" long 1/4 hex bolt or a 8 mm screw - no dice there.

Even the parts and service manuals, which occassionally give the length (in millimeters) still do not specify the actual fastener size.

Sorry..

that's a pain cheers anyways mate, looks like i will just drill out the holes and re-tap to a size i want

I would say go around with a bolt of every size and see what fits where first, rather than drilling them out. Make note of how many and what length, then just get what you need in either 18-8 or 304 stainless. Not 100% but I don't think they use metric.

Imperial: -------------------Closest Metric Equivalent:
10-24 -----------------------M5 x 0.8
1/4-20 ----------------------M6 x 1.0
5/16-18 --------------------M8 x 1.25
3/8-16 ---------------------M10 x 1.5

What size bolt is the bolt that makes your mercury 250 to go into limp mode and doesn't let the trim work

The bolt on the trim rod swivel?
