I'd lay odds it's due to lighter load when the kids are in it (not trying to say anything about your weight...)

Might throw a couple of sandbags in the back next time the lids are playing.

Good idea re the prop.

It does plane with me on board and i'll admit to 90 something kg. I reckon the kids are more like 70 between them.

I'll get them to put the fuel and anchor etc in the stern.

Don't know that brand model, but have it clear now about floor type, assume it has a standard transom, not a transom mount, right ? If so, could it be a long shaft transom and you are using a short shaft engine. If the transom measures 15"-17" it's a short one.

If 20"-22" with same engine + badly trimmed, or a combination of both, there's your aireation problem, assuming prop is working ok.

Happy Boating

Definitely short shaft transom.

Will have a play with the trim.
