I'd go with that .. . Merc mariners use a plastic case for the impellor.. dunno about soozies.. but I cant see how you would get an all or nothing situation ? unless frost has done some damage somewhere somehow ?

Codders, have you got an IR thermometer-or any other way of telling if it's getting too hot?

I'd drop the leg off anyway though and check the impeller.

I reckon Codders needs to poke his wire in a bit deeper.

I have got an IR thermometer - will give it and go.

And yes maybe I do need to shove it in further - how far is too far? Seriously though are we talking regular sort of depth or a gynecological examination?

Mad idea I know, but why not just have it serviced by a man who can

That would be the easy way out and not in the best sporting practice of RIBnet

Very true and with the amount they charge no chance.

Muc rather do it myself anyway - it's the only way to learn.

In my case this often becomes 'its the only way to break ,learn ,& then pay someone more to fix it that it would have cost in the first place.'

I love taking things apart - engines/gearboxes/lathes/milling machines etc etc - I usually put them back together as well...............

So I will prob just wade in there for a nose.

Youtube is amazing - there are even videos of people changing impellers!!!

Usually, there is a length of tubing that connects the telltale nozzle to the block. Perhaps you can disconnect it at the block end and see if you're getting pressure (or water) there?

I found blowing a jet of compressed air or a high pressure stream of water into the telltale on my Honda 40 would often clear things up. For some reason, it was pretty sensitive to clogging up (may have been from blowing the crap back into the motor though, now that I think about it.)
