It may be worth trying to borrow another engine and see how that performs on your boat. This could save a load of hassle.
I have NEVER used a pressure gauge on my tubes. I blow the tubes up until they are solid then I do the airdeck until I can put no more air into it and then I do the keel likewise.
I suspect that there is not much wrong here and would strongly recommend borrowing another engine for a short try out.
Thanks Keith... on the Engines section some of the lads have assisted and are confirming that there is an ignition problem...it´s now in the workshop...pretty peed off as my local marine was paid to look at it and get it in decent order before I shipped it overseas...
