Engine servicing advice

Regards weak tell tale. Did you remove thermostat and clean the housing too? You'll need a new gasket if you take it off. Its normal to get a build up of salt here which crystallises at the end of the season regardless of flushing. Run it to operating temperature with muffs, etc.

You could also check the cooling water jacket at the side of the engine, again you'll need a gasket if you remove to inspect. Use a scalpel or razor blade to remove old gasket material, and torque bolts in sequence - however I'd only do this if you get an overheat alarm.

I haven't done anything other than replace the impellor and the gear oil. I don't have a manual of any kind for this motor and Google has drawn a blank so whereabouts would i expect to find the thermostat housing?

Also, do I have to buy Salt-x from the states or is there a UK supplier?

Thanks for all the help guys.

The thermostat sits in the bell housing at the top of the engine (normally a couple of 10mm bolts - but looks like the Yammie has four). You'll see it here at 6.31. Interestingly this engine doesn't have a tell tale on muffs, but does when placed in a tank. Like it when he says he's not going to rev it much without the prop... could have fooled me!

Check out this link too regards undoing the bolts. The last thing you want is one of the bolts shearing. Use a smear of marine grease on them when installing. Seems there's a poppet valve on this engine too.

If the whole thing is all clagged up then the idea of a salt flush of some kind seems like a good idea. In the absense of salt-x which I cant seem to find for sale in the uk, would this http://www.saltoff.co.uk/online-stor...=0&sort=normal be a decent alt?

A decent amount of white vinegar in water would be a good alternative. say, 1:3 vinegar to water, or more, if you don't mind spending the money.
