I currently have 2 Aerotec 3800s with 15hp 2-strokes. I've also used 25hp and 9.8hp motors, but didn't keep them.
Buy Whisper's motor!
I'd echo this - the 25 I run is about 50KG but I only ever 'carry it' about 2 yards max - from the boot to the transom and back again.
Lightly loaded it doesn't show much over a 15, but in matching boats on the same day a 15 was at WOT , while I was about half - both doing about 18 knts - but the 15 was 2 up and I was 3 up with a fair amount of 'stuff' in the boat.
Its only on a heavy boat you notice the extra power - but you notice the extra weight everytime you lift the engine.
Would I buy a Parsun - actually I probably woudl if the price was right - mainly as I like to look after 'stuff' so it would be cared for ( less liekely to pack up) and if its got a warranty with nearby dealer - I'd give it a go.
