Impeller change for dummies

[AJ.]

So what you are saying is I have not scrubbed enough.

OK will give it another go maybe I'll try the missus toothpaste that has advanced whitening in it

If you can still feel small lines go for it, toothpaste and 3M very used Scotchbrite pads do wonders. Can you believe this is a 600 hours worked impeller flipped and interior liner, lower plate polished every 150 worked hours. Still with original 2007 water pump and peeing better than a teenager on a constant all year used outboard.

Took your advice and gave it a go. Certainly looks and feels smoother its a bobby dazzler!

Do same to impeller liner if needed, don't forget to apply some light grease coat to shaft upper splines before bolting back LU to middle leg.

The Engine is all back together again.

Carried out oil change, impeller change, new spark plugs and fuel filter, removed prop and greased shaft.

Put 12l of Shell unleaded in the fuel tank with 240ml of Quicksilver TCW3 50:1 mix.

Seems a bit smokey, doesn't seem normal to me I ran it and it stayed like this for 10mins.

Is this normal

Wow that is smokey... like a scene from the Sweeney!

Are you 100% sure it's the right sparks and gap? Only other thing could be fuel oil mix.

[AJ.]

Spark plugs are brand new and the ones recommended in the manual. I will take them out and check the gap, the ones I replaced looked ok so I can always put them back in and see if it makes a difference.

Never had a 2 smoke before but know they shouldn't smoke that much. I carefully measured using a measuring jug the correct amount of tcw3 for 12l of unleaded.

I don't know anything about the history of this engine, and how long it has not been used for. Would have thought any crap would have burnt out after 10mins, didn't seem to get any better.

Im going to be like Uncle Buck but on the water

AJ, if you've run the engine for 10 mins or so in a tank it will be smokey- nothing to worry about as its not burning the oil completely. Two strokes are all the same with the exception of the direct injected ones. As soon as you put that engine in the water and get it in gear with a bit of load then the smoke will disappear as its the oil is getting burnt properly. Hope this helps.

Cheers Peter,

Ok, well I'll double check the spark plugs tomorrow and take it out over the weekend and see how it gets on.

Hopefully try not to attract to much attention and 999 calls saying there is a guy driving a SIB which is on fire

[Locozodiac]

You certainly are not at idle speed, seems quite smoky. Don't know by liters, but it's around 80 ml per 3.80 ltr/gallon. Plugs must be gapped tight to 1.0 mm. Plugs must look dark brown when running for some time at wot.

Hi all,

Locozodiac - into liters that works out at 253ml. So I am about right for the oil mix.

Took my new 2.9m SIB out today and it was as much fun as the RC.

Peter - Engine was fine as suggested once it was pushing the SIB smoke died off and ran sweet as a nut.

With 2 big adults 33 stone combined it got on the plane once we shimmied up to the front. With just me it was an absolute hoot not giggled like a big girl in ages.

Just want to say big thanks to everyone who replied on this thread your help and advise has been really appreciated
