Interesting - is one more healthy for the engine itself? I want the engine to last as long as possible without degrading its condition, based on that which would you suggest? The dealer is a specialist marine boat/engine company with a very good reputation so I do trust their recommendation of 100:1.

As I said earlier I have the same engine as you but one year older and with a Mariner hood. I bought it from its first owner and have all the original paperwork plus manual. As the dealer has told you the correct ratio for this outboard is 100:1. However in the manual it states for commercial use 50:1 is advised.

It is quite likely with the low hours most private use outboards get it would last a lifetime on 100:1. Also bear in mind at this ratio you get minimal smoke and less chance of plug fouling if trolling at slow speeds.

So in truth anything between 50:1 and 100:1 will be fine and is a personal choice.

I run at 75:1 or 80:1.

Whatever ratio you decide on I'd advise precise measurement and sticking to a known brand oil.

Marine mechanics have told me always 50-1 even on a 100-1

100;1 is too lean, 75.1 or 50 is the way to go,especially on unleaded. they probably want your business when the piston rings have worn down hence telling you to run it lean, if its advance marine telling you that then that figures!!

I reckon I'll go with 75:1, sounds like a good compromise, if not a little more mathematically taxing lol.

I picked up the T38 and the engine today, it all fits VERY easily into my BMW 3 series with the rear seats folded down and I'm easily able to lift both in and out of the car, so I'm really pleased! Bought two buoyancy jackets too, now I'm looking for a VHF radio and my friend (a HAM enthusiast) has this for sale:

Two Way Radio KG-679E

He wants 40 for it, boxed, unused and brand new together with the programming cable - is this suitable for marine use, i.e. does it have the appropriate frequency?
