Hi I’ve recently bought a new boat with a mercury 2stroke 50hp, with quicksilver controls. the boat is from mid 90s and engine serial number I think is (09629963) ? Took it out yesterday and it starts instantly, and idles well, I have no rev gauge.. but at I’d say half throttle it trundled along lovely all day long! When you try to go faster it’ll sit on the plane for 2 minutes then shudders and tries to die ( recovered by dropping the throttle) my mind points straight to fuel starvation but although mechanically minded have not worked on outboards. Fuel lines outside the engine are seemingly ok and plastic filter looks new. It had new plugs at beginning of this season. Happy to delve in but want some direction first. ( putting the boat in water to test is quite an ordeal so want to eliminate as much as possible before trying. Sorry for long post, trying to be comprehensive. Thanks. Dan.
