Re: Yamaha outboard no water through tell tail
Unfortunately replacing, or checking the impeller is about the only thing you can do.
Even if 5 of the six blades are still there and one is blocking the path - you have to dig it out.
And when the next blade throws off - you'll for sure be 5 miles from where you want to be.
Good news, doesn't take much in the way of tools. Most outboards of that size are pretty standard - put it on it's head, pop the four bolts on the bottom, pry it open etc..
Probably all of it is the same (about a 10mm socket). Maybe if you are lucky you got someone on your pier to help.
Or if money is in more supply than handiness - take it to the shop and pony up the bucks.
Lessons learned are opportunities earned.
