last 3 big engines I've had, yamaha 40 2 stroke, marine 50 4 stroke, and a johnson 40 2 stroke were all a nightmare, poor starters, poor runners, cutting out etc
came back from PA lynch like new engines
took a small 8hp yam to the place up the tyne, needed a recoil spring and a service.
after 8 weeks being there I was eventually told it was beyond repair, as they couldn't get a recoil spring but they still wanted over £200 for the service, but would never explain to me how they managed to service an engine that couldn't be started due to a broken recoil spring, let alone justifying £200 to service an 8hp 2 stroke engine
the mariner 50 needed a full service, electric choke solenoid replaced and the choke system rebuilt
bill was £120
