I have seen the intake screen behind the prop be full of sediment. This is very hard to see. Then the motor only gets water through the tiny holes in the bypass cover, which will be ok at idle for a few minutes. Something to think about.

Great advice, especially if you are running it in a barrel with dirty/oily water and debris such as leaves/pine needles.  The inside looks OK, so doubt you have an issue with water leaking in from the exhaust cover…
