Another season, another round of outboard problems!
Wondering whether anyone can identify the cause of this sound?
I had the outboard serviced this year (as I do every year) and the mechanic said it ran beautifully in his tank. When it went back onto the boat (with my fuel system), it idled roughly and then started in with the sound recorded in the linked video.
I figured it's a problem with my fuel system given that the outboard reportedly ran fine in the mechanic's tank. The fuel line and fuel assembly were old and in need of update, so I replaced them. Now also using using fresh fuel, but "clicking" or "knocking" sound is still there.
The problem only seems to kick in when the throttle is set to the "start" setting. When revs are any lower, no problem.
Any thoughts would be appreciated.
