2 Stroke Winterisation

[Bigplumbs]

When I first came to this forum I worried quite a lot about winterising my outboards which are 2 strokes. Now I do nothing to them perhaps put some fuel stabiliser in the petrol tank.

So what do other do to their 2 stroks because I basically think that there us nothing that needs doing

I don't even bother with fuel stabalisation I just run it up on the muffs or at the local lake every now and again...

I did do a post on 2-strokes on previous forum.

I drop gearbox, change water pump impeller, top up oil, grease all appropriate parts.
Spray water dispersant over everything under the hood (while all still warm)
Change in line fuel filter/separator.

Remove prop.
Cover shaft & lower gearbox with plastic bag to prevent bugs/dirt entry.
Insert wood block to hold weight of engine ...rather than on rams.

Take battery off and put on soak charge.
Spray all electrical connectors & plugs with ‘Corossion Block’. (marine ver of AC50)

Hi all - just wanted to expand the debate on fuel stabilisers - last year, my 2012 E-Tec 25 cost me an awful lot of money for a new vapour separator and high-pressure fuel pump...the dealer told me that due to what's in fuel these days (I can't recall whether it's more or less ethanol) leads to the sort of failure I experienced: apparently this is common...every week this dealer is doing this sort of work. There are two other possible causes 1. I ran out of fuel - well, actually the fuel line was not connected - schoolboy error in a rush to get out 2. I didn't actually winterise the motor the year before - I should point out the boat is kept in a heated garage.

Overall hours at the time of the breakdown in 2017 less than 30...

This year, thanks to the good weather, I've put another 30 on so far without a problem.

So, minded now to do proper 'pre-flight checks' and to always winterise, do people think that things like the 2+4 additives are worth it, or even necessary?

Thanks

Simon.

This would only be an issue if using E5 or E10 Ethanol fuels. ( common in US)
There are not used on forecourt pumps in the UK (at least not yet)
So no risk of damaging your engine.

I think the background to Ethanol fuels is manufacturing of Ethanol from crops (not oil) .
