I have just recently bought an
I have just recently bought an old yamaha 40hp which is probably late 70's or early eighties. Took it out for the first time yesterday and soon realised it has a problem in that when I tried to accelerate in gear it cuts out as if maybe starved of fuel or wont power up under load ?
The engine starts ok and pumps plenty of water then once it heats up for a few mins or so it idles ok. It revs freely and highly when in neutral and powers the boat ok away from a standstill and I had it out running for over an hour but just wont go any higher than a few mph without cutting out?
Any ideas or help would be appreciated.
