It seems to be shifting water, it's just it's going out through a fairly big hole so it doesn't look as impressive as some people's (do I have tell-tale envy?
). I'd be grateful for any reassurances though.
Also, there's quite a lot of 'shit' of various kinds under the hood. What's the best way to clean all this off? Get stuck in there with an oily rag? I'm guessing we don't want to be sloshing water around in there with the electrics.
Are you running it in a test tank or on 'muffs'?
Some engines don't seem to get a good telltale on muffs, only in the tank.
I would recommend a purpose made spray degreaser thats safe on rubber and plastic, such as:
Yamalube Parts Cleaner - Multipurpose Degreaser - Aerosol | eBay
A toothbrush is great for Agitating the 'shit' whilst you wash it away with the cleaner.
Then protect with good old merc corrosion guard.
Your video is still proccessing so I can't comment on the tell tale vid.
