Nah mate, not me mate, Little Englander, fight them on the beaches, we won in 1966, they need us more than we need them!

Anyway back to the question, why do some people say "T" and not "S"?

On the continent, Johnny Foreigner refers to 2 Stroke as “ Deux Temp” as in “Two Time” or 2T.
4 Stroke is “Quatre Temp” or “Four time” = 4T
“Time” & “stroke” are interchangeable.

Two Strokes in the UK
v
Two Timing in France

Who'da thunk it?

Is it worth running the 4 stroke 20hp dry at end of day like you do on 2 strokes to prevent old fuel sitting or is this not wise?
I'm wondering what the shelf life of small sub 30 efi engines are? I had a 15hp 4 that without a manual choke to tinker became hard to start around 10yr mark.

If 2 strokes are more reliable /safer perhaps the rnli could push for the ban of 2 strokes to be lifted on engines under 30hp ?

A 2 stroke requires far less servicing than a 4 stroke

I have 10, 2 stroke outboards ranging fro 2 hp to 200 hp and 1, 4 stroke. The 2 strokes are way lighter, easier to start and way more reliable

2 strokes can still be bought for commercial applications so the rnli are ok for now. Not sure about running a 4 stroke injection engine dry as there will always be some fuel residue remaining & the situation may be worse with air in the fuel system combined with a little fuel & some moisture. Keeping the fuel clean and moisture free is the key fuel conditioners may help, extra filtration is almost a must have. Using the engine regularly is the best way to keep it reliable as they thrive on use. 2 strokes are not more reliable per say they are just simpler & tollerate a degree of abuse better. Your far more likely to melt a piston or loose a ring down a port with a 2 stroke than a modern 4 stroke. Put the two side by side the 4 stroke will probably run more hours than the two stroke. But hardly anyone wears out an outboard, usually corrosion or neglect gets them first

Instead of running the fuel dry, which I'm not sure is the right thing to be doing, I run my 4s efi a couple of times a month for 10 - 15 mins. Keeps the fuel in the OB fresh and lubricates the upper part of the OB.

I wouldn’t. The EFI system is sealed, so the fuel shouldn’t evaporate & cause gumming as in carbs.

2 Takt/ 4 Takt is German for 2 Stoke/ 4 Stroke. As said good for the French too [emoji851]

Yes aware they can be bought for commercial use such as RNLI - my thinking is, if the smaller 2 stroke outboards, are considered superior at the moment by such organisations promoting sea safety, is it time for regulators to reconsider the ban of these engines being sold to private users?

Thanks for tip on not running efi dry - I thought this might be the case.

I'm all for running engines frequently - they do seem to thrive on regular use. The sound and smell of 2 stroke firing up is always good!

Running an engine when you are not using it is generally not wise. Lots of reasons why not. Have a Google and you will see why

Why don't you tell everyone who's reading this thread, or maybe post a link. It would be so much easier than trying to find it on Google.

Are you refering to annoying the neighbours with noise?

Never heard of anything wrong with running engine in a tank/ with muffs for 15 mins . Even encouraged after salt water use.

Hi Steve509926, you know the craic with this one. Banned from pretty much every forum/chatroom he ever joined - multiple times in most cases. He thrives on baiting well meaning posters with passive aggressive brain mulch. Debate the point with him at your peril - it's pinnacle pig wrestling...

There's an Ignore button somewhere if he's grating

The worrying thing is some inexperienced folk might just believe his cr@p advice & experienced posters don't correct it because they know its not worth taking the bait it ends up only his sh1t advice is all thats left

Granted, but he's still a tarbaby, you can't meaningfully engage with him without getting mired. Perhaps well meaning posters could just post corrections/suggestions without eliciting a response from him - because it's going to be the same mulch talk - mwaa mwaa mwaa...

[Steve509926]

Come on guys, give Dennis the chance to share his experience and post the links to the source of his knowledge gained from Google. I for one would like to read it so that I can, if it's proven, correct the errors of my ways. I think we should all listen to the knowledge gained from someone with so much experience working with outboard motors, after all he has 11.

Steady on chaps, or he’ll play the “Bully” card, as he usually does as he approaches the end of his current tenure. Don’t worry he’ll be back under a different nom-de-plume.
