This is a three part problem. I have a 1989 35 hp mercury that is very difficult to prime. All the lines seem connected tightly, but the ball never gets firm. After it starts and I run across the lake, it's not uncommon for me to need to prime the ball again after stopping for only five minutes. When throttling down, (e.g. when loading or approaching a dock) the boat almost always dies. I've changed the plugs and fuel filter, and I'm planning on tackling the carb next. Any guidance or thoughts on these problems would be greatly appreciated.
Thanks in advance.
