Hi Rick,
Seeing this post made me realise I never did give you any feedback after fitting your SSI last year. The unit has been working really well without fault. I modified the exhaust at the same time (and have now changed it again) so can't comment of any performance improvements, although to be honest I don't think performance has improved.
Having said that, cold and hot starting is definitely better, it picks up better with less lag or flat spot and generally just runs better. It always comes back to a more consistent and reliable idle too, so I'm really happy with it thanks.
I haven't been through any really deep water, but deep enough for the engine to go very quiet (as presumably the fan is pushing water over the cylinders..) It hasn't missed a beat, although I did make a little 'shroud' to go round the dizzy as a precaution, whether its needed or not.
There's a youtube clip here:

Again, thanks for your great service and to anyone thinking of installing one, I'd definitely recommend it.
