Can anyone tell me if the Yanmar 2GM has a cold start in the respect of glow plugs, manifold pre heat, or pump over fuel?

Lots of welly and a wee prayer should work as no other help.

Set the throttle to full before cranking - according to my service manual (but not mentioned in the Yanmar owners manual) this allows extra fuel into the injectors. If it fails to start pull throttle back then to full before further cranking to get back to the cold start setting.
If that doesn't work spin it up with decompression levers open then drop them in one at a time.
Have fun.

no glow plugs or pre heat for sure.

Could also use a 12v hairdryer from caravan shop down the air intake - make sure it doesn't reduce cranking speed.

Taking this route I prefer a Plumber's gas blow torch carefuly directed towards (not directly in) the air intake. Works a treat on Sulzers, Paxman, General Motors etc, but these are one hell of a lot bigger.

what a dangerous method - trying to blow yourself up whilst starting- all kinds of undetectable sparks running around!!!!!

Yeh well, you best stay inside incase you slip on the ice.

As others have said - no pre-heat or glow plugs. Make sure the battery is OK then just give it plenty of throttle and it should start. If not then you have some sort of problem.

Not sure if there is a problem yet, the boat is out of the water and had it's survey yesterday and I noticed a tin of "Easy Start" and a half tin of "Injector Cleaner" in one of the lockers. Points towards engine start problems or they are carried just in case?

Before starting, with the throttle setting on full give the engine stop cable a couple of pulls to its full extent. IIRC this gives a couple of extra shots of fuel ... it certainly works a treat every time, even in the very coldest weather.

I've had both a 1GM and now a 2GM and have never needed either Easy Start or the need for an injector cleaner.
One other thing that might be worth mentioning is that Yanmar recommend running the engine up to full power every so often and 2 or 3 times before turning the engine off. I understand that this is to reduce the build up of carbon deposits in the exhaust/cooling water mixing elbow. Don't know if such a build up would give starting problems but it might do.

Got me worried now. I found a half used tube of Anusol in one of my lockers after I bought the boat.

Easy start is very much a last resort and as dangerous as blow torch!
I recently changed my 2GM for a 3YM but i've still got 2 reconditioned and tested injectors for a 2GM. If interested pm me an offer.

I have a 3gm and have never had a problem starting it, not even needed to apply throttle. No preheater etc.

Check injectors for coke buildup, as well as using full throttle.

Could be a cautious owner, injector cleaner is a sensible precaution from time to time. I have a tin of 'easy start' on my boat but only used once or twice, before I discovered how to start it properly (see my earlier post). However, I have heard that regular use of "easy start" is addictive and after a while the engine is unlikely to start without it. Something to do with destroying the natural carbon seal around the top of older pistons.
Incidentally, if you do have starting problems do not crank for more than 30 sec at a time then take a break - otherwise it does overheat the bearings on the starter motor. I kept cranking one winter when air temp was below zero and alternator was comming on load as engine tried to fire .... now have a new starter and time delay on alternator.
Have fun.

I suggest you check how good the compression is first, see if you can crank by hand with the decompression levers down,one at a time. you should not be able to get it past compression on either cylinder.If you dont have a starting handle putting a socket and t-bar on the crank nut has same effect.
