Xr2 starts, but dies when in water?

I have an old XR2 150 motor which was struggling to start. It's had new plus, top seal, stator etc. all compression is spot on. now starts and ticks over fine. Will Rev on the slipway, but as soon as it goes into water and you get above 2000revs it dies. Any ideas what to check/replace next? It's baffled a mechanic for four months so any ideas gratefully received.

Thanks

That sounds like a stator gone down

Thanks for the replies. It has got a brand new stator on it. Also had a diaphram kit. If it's revving it must be pulling fuel so got to be mechanical or electrical? Switches?

Assuming this engine worked fine on the boat before and you've not changed prop etc then high speed side of stator is the most likely cause. Just because you have a new stator doesn't mean its ok!

Strap the boat to the trailer, back it into the water. Put in gear and start it.
Put a timing light on and bring up revs until you have problem, see if spark goes out on that cylinder. Test other 5 same way...

Or just change the stator...
