Impeller - need some tips.

2004 Yamaha 150 carbed 2 stroke

1) My question is, does the shift linkage slide right out or is there a bolt to remove like on the johnson and suzuki engines?

2) Should be boat be in neutral when I drop the lower unit?

Thanks, I bought a new impeller today. I've changed them on 5 or so engines (Johnnyrudes and 1 old suzuki) but never on a Yamaha.

Anything else I should know or is it just like the others I've done?

pretty straight forward, Shaft just drops out and you good to go.

yammies one of the easiest. yours might have that collar on the shaft above the water pump. if so throw up a post and i will do what i can to help.

put it in forward gear, it makes it easier to spin the shaft to get teh crank splines to line up. The water pump is allmost a direct copy of the john rude design, with one exception, there is a metal sleve that slides over a plastic retainer, that on top of aseries of shims. I never have figured out what its there for, never tried to run one with out these parts. Just pay attention to how it comes apart after you remove the upper housing. The key can be a pain, its usually stuck in the shaft and takes a chisel and hammer to get it out, I allways sand the sides of the new key so it won't be such a tight fit.

Just the advice I was looking for - thanks guys. I haven't tackled it yet but I have the new impeller in my laptop bag. Its going to be at least 2 weeks before I can work on it, but now I'm prepared!
