The assembly of the gear is very complicated, thus impeller replacement is too pricy at the marine services. Does any company produces impellers from life- long lasting materials, as titanium or the special alloy?

Having fought one of these many times, I suggest the following to make the replacement of the leg easier. Tip. mark the position of the gear change clamp behind the grommet hole -before undoing it- this is critical! I use correction white paint. First, remove the engine from the boat and empty the tank. Fit the engine transom clamps with an 18" length of 4" x 2" timber and clamp the engine upside down in a vice. Even horizontal is easier than down. Then tighten the steering clamp. Using gravity makes it so much easier! A small LED light is essential, together with a couple of short lengths of 3mm welding rod bent into a 'U' shape at the end, to hold the water tube and gear link clamp in place whilst sliding the shaft into the spline in the engine. No resistance should be encountered if it's in the right place in the splines. If at first, you don't succeed etc--- takes a bit of practice. One hour should do it!! Have fun-Peter.

Great video but one thing. Use some silicon o ring grease on the impeller and use the absolute minimal amount. The reason is that while it is all well lubricated any sand etc... will be caught up in the grease and create extra impeller wear.

I’ve just managed to split the leg on mine (same engine). I should have done this yearly, it took a lot of persuasion to get the leg away from the power head. The issue was not the drive shaft seized into the head as I thought. It was the steel stud at the bottom seized into the aluminium casting. This only released after quite a lot of heat on the stud from a mini blowtorch and some enthusiastic whacking with a large hammer and a piece of hardwood. (Careful not to break the cavitation plate!) hit it near the front. - also try hanging the leg upside down and spraying a load of releasing lube in there - leave overnight or even longer.

@@plymouthwelshboy after reading that id say your thought process seems logical. Id think the same, ot would simply wash away😉 This is my first outboard. May i ask, the stream of water from the pump is it constant or does the stream come and go? I see in a service manual that my lehr has a thermostat, so i would assume that the stream of water will come and go as the thermostat opens and closes. But ive nothing, nor any experience, to compare. This unit sat for 2 years and fired right up. I have to say, for all the negative things i see concerning lehr im quite impressed by this little unit.

Ferenc that is an issue and a fair point. It is waterproof grease and tends to stick better but eventually over time it will break down. Also be aware that in one small clip managed to reverse the film clip. The spindle should be spun the opposite way to the way I do it in the film 😄

Have just done the impellor task. In my case the splines lined up easily but my clamp fell off, which was a nightmare!

Yo be honest I have absolutely no idea. Given that there is a inlet valve just above the prop and an exit stream of water when engine is running....then I'd expect dribbles of water to appear anywhere below the engine but that's just me. I always thought that cooling water went up the shaft ....but as a very amateur sailor who has only done his engine service twice ....I truthfully don't know...sorry 🤔🙄😔

This foxed me last year, my motor is the same. The owners manual confirms that it’s the oil level. So this is a systemic problem and your solution of upending the unit is the best work around. I abandoned the job last season, but will complete this year. There’s no schedule for this job in the manual. I’d suggest using a 500gm weighing scales (big river company) to confirm quantity injected. Very informative, thanks.

Pretty much every lower unit of that type that I've seen, that hole is clear through into the gearcase void. I'd say its a manufacturing fault. That oil you removed initially has water in it from the look of it. Hard to see how that gearbox has been properly serviced without that vent being functional......keen to hear the outcome.

adding grease to the impeller and housing is the worse thing to do! Grease can accelerate the deterioration of the rubber impeller. That's why you use washing up liquid or a special impeller lubricant. Given the very small parts that could go missing I would not attempt this over decking either. Great to do these jobs yourself but without the right knowledge you can make some expensive mistakes.....trust me, I know :)
