The guy tried to sell this to me too!!!
I took one look at the engine and walked away. It will chew fuel attached to a boat like that!!
The console needs to be ripped out, the deck did look dubious, the fuel filler in a foot above the deck, the aux is on some strange contraption.....the list went on.
However the exterior hull was ok and tubes looked firm.
If I was you I'd have a chat to Tim M about his arctic on here
Halmatic Arctic 22 - no engine - offers
Strikes me its a bit less of an unknown quantity and you could re-engine how you liked.
(There are 2x 150hp Yamaha HDPI's on boatandoutoards @ £3.5k ea!)
The arctic is a big heavy boat for a dive club anyway. You'd need a monster tow vehicle to shift it anywhere.
Have a look at something like this......
Lots easier to trailer anywhere and loads cheaper to run. The back pods can be completely removed to store gear too.
