The value of empirical data.

I should have known better and Latestarter will tell me off.

The dash said stbd engine was running at 100degs, so I sorted a good clean descaled spare headertank/heat exchanger, fitted it with a new thermostat, new impeller with new cover plate, seemed to be masses of raw water flooding through.

Ran the engine up to temp, dash still says 100 degs.

Borrowed an infra red thermometer, engine is spot on at 80 degs, dash is wrong....sod it. not sure if gauge or sender yet, will do some swapping over to find out. Should have done that in the first place!

Ah... At least that's resolved then, perhaps you should have listened to the bloke who suggested you should cross the gauges over to check for a misread when you first pointed it out on the way to Cowes....

Or perhaps not, given that I have now got 16 valves fitted to 2 refurbished heads, unfortunately they are held in with 33 valve collets! I broke one, ham fisted prat

Yes...but the looms don't reach across....my obsession with not having big tangled loops of extra wire.

I'm a bit concerned you've managed to fit 33 collets....

Don't feel too bad, 20 years ago I had a mate who rebuilt the top end of his Honda CB750 because it had a tiny rattley sound, once completed the rattle was still there. Noise eventually traced to big bunch of keys in the ignition

I thought at Seawork that you said engine building was easy Paul?

Had the same issue, took the gauge home, put it under a hair dryer for 5 minutes then left it out to 'dry' in the house for a week.
Put it back in and it was cured.
3 months later it is starting to do the same, a sharp tap with a knuckle fixes it.......for now. Neds a new gauge I suppose really.
