Bolt left over!

Recently had to remove the trim motor of my Tohatsu 2-stroke 60hp to rebuild it. I also removed the thermostat (needed a new gasket), the electric box cover (where solenoids are located), the PTT wiring harness, etc. Everything that came off I placed in one location in the garage on a bit of wood. I was meticulous in doing this. Only trouble is, I have a bolt left over after it's been put back together! 99.9% sure it's related to the engine and not something from another project. The bolt is an 8mm-fit allen-head with washer, alloy, not stainless-steel.

From what I can tell the very small writing on it says H S K (above) and A 2 - 7 0. Bu**ered if I know where it goes? It didn't seem to hold anything on (which begs the question) "why did I remove it?"

Anyone with a Twatsoo out there (mid-sized 2-stroke) - can you please have a quick scan at your engine and help me out. I've posted a picture for reference.

A2-70 means it's made of 304 stainless, 700N/mm sq.
Not that this'll help you any

Cheers martini. 304 stainless certainly seems to link it to the engine. The plot thickens!

Just a stab in the dark here, but I have very similar screws holding my PT motor onto the "manifold" below.

M8 is going to be holding something big - ish on.

Just to keep my fitters on the ball it has been not unknown for me to chuck in a spare bolt into their magnetic tray whilst they were busy on a project ... in fairness .. I always owned up to it

Obvious I know but are you sure it's not one of the bolts that connect the trim motor to the trim pump? May be hidden round the other side up against the saddle?

The trim motor housing didn't have to be fully removed from the pump. The motor was held in place with 4 x cross-head 10mm bolts, rubber 'o' rings, etc. Undo these - and the motor housing can be extracted. I'll have another look though - to see if there's anything obvious.
