quick question
Do the 4 stroke engines seem any more reliable than a 2 stroke ???

Cannot comment on statistics but a 2 stroke (maintained) is not exactly unreliable. Not a reason to base the 2 vs 4 stroke decision on TBH IMHO.

I was thinking that was Likely to be the case, slightly more heavy but a lot more reliable

much much more to go wrong on 4stroke - sensors etc. if by reliable you mean easier to start then i would say yes.

I have had bad expierience with older outboards in the past which is why I asked the question, I want to pull the cord and it start no hassle.

Hard to find 4 stroke outboards of the ages that the remaining 2 strokes are. But 4 strokes have been quite common and reliable as I/O stern drives for decades. The bellows seem to be the weakest link and 4 stroke outboards don't have those. High performance high pressure injection 2 strokes have planty to go wrong with them too so its not a simple comparison to make.
In small pull start sizes I would say the biggest weak link is the carburator getting gunked up and both 2 and 4 stroke models would be equally susceptible.

I used to have an old blue band mercury years ago and I spent a fortune try to get that pain in the arse to run right and it left a sour taste in my mouth with outboards.

I watch somebody paddling a boat in, with one of those.
they said it was working fine, then suddenly stopped...been out 2 days and switch to second tank of fuel they just filled....
I asked them, all the normal questions- I then said have you checked the two stroke oil - they said it was a 4 stroke and pointed out the 4 Cylinder sticker....I was puzzled it looked an old engine to be s 4 Stroke! I asked them to remove the engine cover so we could check to see if there was a sump and dip stick....on doing that I confirm it was a 2 stroke and they ceased engine!

I used to find that again with my blueband it would run fine then just stop for no reason and refuse to start then a couple of hours later it would start up straight away no issue. ![bang](https://www.rib.net/forum/images/smilies/banghead.gif)
But at least i knew it was a 2 stroke

I think the best combination for a boat has to be inboard diesel and a stern drive or jet drive for reliability and economy, one day perhaps

Do you have any experience of other outboards since?

Don't let an old blueband put you off 2-strokes or outboards in general. They've come on a bit since then, but with progress, comes technology and with technology, you lose simplicity and easily-repairability, so there's always an element of risk in 'modern' technology.

Nice one! Always good to have a plan, especially if it involves a bigger engine.
