Re: Yamaha outboard no water through tell tail

I have had many outboards over the years. The only one I ever replaced an impeller on was a 35HP two stroke Evinrude which I had for 25 years with a lot of salt water use. About 2 years ago I replaced the impeller due to it heating only at very low trolling speeds. Have to admit that I ran it "dry" from time to time, just enough to make sure it would fire after sitting over the winter, shouldn't have done that. As mentioned earlier, suggest you leave the impeller as the last resort.

I do believe that you got 25 years out of an impeller. However, Why would you ever trust a motor with an impeller that is over 3 to 5 years old? Ive seen way to many fail. What is the 2 main causes of motor failure. overheating and lack of oil. Just not a common sense thing to do. Just change it. Its easy and inexpensive.

Re: Yamaha outboard no water through tell tail

Could be plugged internal cooling passages. That was the problem with my Yamaha 2hp when it didn't spit water during its test run this spring. Impeller was fine.

You are right, I am sure. On all my other motors there was never any sign of them going bad. On the 35 HP it started very gradually and very slowly got worse. To the best of my knowledge all the motors had a solid rubber puk type thing mounted inside a concentric. Never saw one, from the parts diagram, that had "vanes" which can break off. My only point to the OP is to try the easy things first before tearing into the lower unit

Re: Yamaha outboard no water through tell tail

Thanks for your replies,

If the motor has not been used for 5 years could the impella not be sort of stuck with salt deposits and just need freeing?

I hear a lot about a blocked coolant pipe, how is the best way to clean it, just poke a wire as far as I can down it? I don't believe there is anyway to flush it out with a garden hose as I don't think there is any facility to flush it out using the garden hose.

Thanks very much

For example how did you clear the internal cooling passages?

Thanks very much

Re: Yamaha outboard no water through tell tail

Thanks for the link, however, unfortunately my outboard does not have the facility to attach a garden hose.

Maybe one of these "one size fits all" flushers that fit over the inlet holes on the lower unit?
