Well done Fred, wasn't jealous when you rang earlier and the photos don't help either, the word called "work" gets in the way at times!!
Hope there is nothing nasty from the impact.
I have been told it is owned by Bono from U2.
You can see where your CD money goes if it is!!!!
May be joining the club they fitted a new fish finder on it!!!

Hi Mike
I had a similar problem and it was the heatexchanger cores scaled up.
Pressure cap would release when under way and nothing would happen if run up on pontoon.
Took it a part and descaled and sorted it.
Good luck with tracing problem, but may be worth checking.
