Managed to get hold of the Tohatsu Service Manual, its a good bit better.
Managed to sort the high rev problem but now lost power, seamed to be that only 2 of the 3 carbs were working. I gave a quick clean of the jets a couple of days ago, but I stripped the carbs fully today and gave them a proper clean to find that the fast jet on one of the carbs had been clogged up.
Whilst reinstalling the carbs I found the timing mark which is situated higher up than where I was looking. So managed to set up the timing as well, hoping to get the boat on the water near the end of the week to see if it has sorted out the running problems.

I have seen a sticking reed cause that symptom, worth having a look with the carbs off. The other thing is the balancing of the carbs would also cause it. Was the engine sitting doing nothing for a while before you tried tuning it ?
The big worry is oil feed; if one of the carbs has been running lean,it's been under oiling the related cylinder.
Your blocked jet could be the obvious cause , if it were me I'd take an airline to all the jets and balance each carb again, just to make sure.
best of luck.
