    Great thought!

    Too bad that wasn’t the answer.

    So the water tube grommet has a hole all the way through that is about a 1/4 inch diameter?

    Did you pull the flush out pug at the back of the power head base to see if water is pumping there? While it’s out, blow air in that passage to make sure it’s going out all the other holes.

    My grommet has been trimmed shorter because it was mucked up. But it has a hole that size right up into the Copper/Brass Coloured water tube. I have taken the flush plug out and while its running it will dribble water. When I has the bottom end and head off of it i was able to blow through the flush hole and had air come out the bottom end at the grommet. Anywhere else i should feel air from? All passages seem clear and I have been able to pass air and a wire through them.

    I suppose all this could possibly be because the grommet is now slightly shorter. I don’t suppose they are readily available?

    The ONLY thing i haven’t taken off is the carb since its combined with the exhaust i believe it its. I have had it off once when i rebuilt the carb and noticed nothing wrong that stood out but i also wasn’t exactly looking. I think that will be my next step.

    I also have to upload pictures here because one is worth a thousand words and i haven’t taken any since first disassembling.

    Unfortunately I’ll be heading out of town fishing for a week soon and then I’ll be starting my schooling as a machinist so this may go onto the back burner for a few weeks. Thankfully its not my main kicker motor or anything.
