So, the same engineer came and ended up bleeding the engine. Looks like he didn"t tighten everything he should have the last time around . The engine seems fine now. No water in the tank it seems.
That's one problem down, 99 to go :/
I'm still keen on getting a new engine and gearbox as I think it will pay off in the future.
My next pressing issue is my electric system. Again , I keep losing power. When I lose power and turn the engine on, i have full power on the boat. I turn off the engine, I lose all of it again. I switch off all systems for a while and when I switch on I have full power again.
A quick question, what do you think of CRR? Any bad experiences?
A thank you for all the good advice so far.
