Leave boat on trailer and use those headphones for cooling. Start engine and put it in gear. Than start fiddling around on all electric wires, connections, plugs and whatever. I once had exactly the same with a motorcycle: water was getting in into a connection wich had a broken rubber seal.
Took me 2 months to find it.

That's a great idea Otilly.

Also I am not 100% sure what software was used as it was the mechanic. Is there a a particular one I should use?

Air in the pickup could be an issue also.. I will try and check that.

Yeh...just chatted to me mate who has a yam F150...there is a relay that limits engine power ( probably by dropping a cylinder) if its not sensing in gear....go onto Boats.net (american site... find your engine and it will give an exploded veiw of the electrics) The idea of running it on the muffs and giving everything a good wiggle is a good start...hope this helps Nik

If it uses YDS 1.33 you can get it on eBay for £50 from a seller in Lithuania the software allows you to drop a cylinder and real-time monitor the engine.

https://rover.ebay.com/rover/0/0/0?m...2F192642709324 Check with the seller

Progress has been made. I had another issue which I thought was unrelated. This was the fact that water was getting into and collecting at the bottom of the engine bay when at speed. I went about looking for this leak and sure enough found it coming from my Speedometer tube which was entering the bottom of the engine head, passing through the engine bay and meant to pass out through the main front section where all major wiring/fuel comes through. This was snapped and would let water into the engine bay to collect. I removed this pipe solving my leak problem and then went for a good burn and couldn't get the engine to cut like I usually could in the previously described problem... My thoughts - perhaps the pooled water was building up and when I hit a wave it was agitating it and causing it to short somthing... I must go for one more good burn and really test her but things are possibly looking up!.*
