Just curious. Has anyone used a borescope camera with an android or iphone connection to inspect raw water system hoses for debris? Especially from the sea water pump back through the the inlet hose to the transom.

I haven't used one for that, but I used it to check piston wash on my snowmobile. I have to say I was extremely impressed how well it worked and how good the picture was. And mine is a cheap $15 camera off Amazon.
