Spent another weekend servicing the boat, and checked out the engine.

There's a 'thingy' on the rocker box, on top of the engine. It's not exactly a lever, but it rotates. It's about the size of a 10p coin. Mind you, you need the dexterity of a microsurgeon and the strength of a coal miner to operate it, though.

On further inspection, by removing the rocker box, it isn't connected to anything. Just a 2cm cylinder stub, with a 8mm slit.

After lubricating it,and turning it back and forth, it now operates somewhat smoothly, but I don't see myself throwing it at the right moment, and crancking the flywheel at the same time.

Am I to conclude that I've got a 2001 without decompression lever, and that the 'thingy' just a dummy?

Perhaps the slit used to hold a cam? The only sure way to solve this puzzle is to take the rocker cover off. Do it carefully and have a spare ready. Look at the valve spring as you rotate the rod. If it pushes on the valve, its a decompression lever.
