I'm fairly sure inboard petrol engines can not be coded. Says something.

To address OP's questions, as others have said im personally unsure of the merits of a diesel in a 6.5m or less, a boat you'd typically be trailering. The second hand choice here will be small partly because the choice of engine & drive for this size package is also small.

7.5m+ and diesel would be my choice, if initial outlay not of concern. An 8m diesel is perhaps 150% - 200% of the cost of an 8m outboard petrol boat.

Ive been in this dilema for a while. Ive always thought the next boat will be diesel but for the same one gets more of a boat by going petrol outboard again... Finally I am putting together an 8.1 diesel scorpion to replace my 7.5 petrol version of the same boat.

Out of interest - what swayed your decision?

Availability and ease of refuelling.

Ask me in 6 mths if I prefer a diesel RIB ! I am realistic, it's heavier, will be less responsive, harder to haul about and launch / recover and more expensive to maintain.

I for one will look forward to the unbiased Feedback

I've always found the Turbo lag and lack of punch in Handleing (on the ones I've tried) a Big hurdle for the type of Boat I do (at pressent) although I do recognise the advantages...especially in larger Rigs.

Went out in my mates 7.5-8m (??) scorpion last summer, think it was running a 260 yanmar??? I can't remember, however I do remember the lag, he said it was slow off the mark
So we're sat there, he throttles up, nothing, then nothing and still nothing, I'm thinking by this time something's wrong, matey then turns around and says if your not constantly trimming the leg it takes even longer to get onto the plane Think I'd rather sit on a 'floating bomb' ( which don't ever exploded ) than die of old age waiting for something to happen!

Wheezy 240hp old school Yanmar diesel on a 8m "sports" rib? Horribly underpowered - no wonder he was twiddling with the trim!

Try that same rib with a 370hp V8 twin turbo Yanmar 8LV

Wonder how the Hyundai SeasAll engines are, the new s270 has a reasonable good power/weight ratio. Have not heard much about them, good or bad.
