What's the difference between boat 2 stroke oil and motorcycle 2 stroke oil apart from the huge price difference. Would it harm an outboard being used in the sea if it had 2 stroke motorcycle oil instead of the dearer marine engine oil?

That's what I use and the 25 hp Suzuki is still going well after ten years use.

I think marine 2 stroke oil is bio degradable so better for the fishes

marine chandler has told me that it's VITAL to use marine oil and not motorcycle oil if I don't want problems with my engine. Having said that, he DOES sell marine 2 stroke oil so does he have a point or is he just looking after his sales of boat oil?

I seem to remember the difference is
Marine oil synthetic mix
motor cycle not
Do not use motorbike 2 stroke in a modern 2 stroke you will ruin it as too thick.

And I didn't know THIS
"A one-hour ride on a boat with a 10-horsepower traditional two-stroke engine emits the same amount of hydrocarbon pollution as driving a modern automobile 40,000km (25,000 miles)."

TCW III oil (marine) is a higher grade.
Apparently the difference is the greater temperature differences in the cylinder.
Red hot then has ice cold seawater thrown on it.
Probably get away with motorcycle 2T oil in warmer summer waters.
Some out boards are air cooled, there should be no reason why they can not run on motorcycle oil.
In France you can but Total TCW III cheap as standard motorcycle oil , just the UK swindlers that charge more they have such a low turn over they need 300% mark up .

I think you need to show this to Chichester Harbour conservation
clearly all two strokes are 300% cleaner at max revs.
RIBs and tenders should be encouraged to navigate at 'best speed '

My local marine repair man says it is to do with the fact that marine engines run at much lower operating temperatures than motor cycles and need a different spec. oil.
