Customer Question
Good morning - I have...
Good morning - I have a 1986 bassmaster boat with an 88hp johnson outboard. The boat will run 200-300 yards and quit, acting like it runs out of gas. Priming the engine will get it started again and then the boat will do the same thing, 200-300 yards and quit. I just recently replaced the fuel line assembly and with the fuel line attached to the motor, the priming bulb will not build any pressure. If the line is disconnected from the engine, the priming bulb will hold pressure. Please help!!!!

Hello. It sounds like you have a faulty fuel pump. The pump is operated by a diaphram that uses the pressure/vacuum of the crankcase to pump fuel, and the diaphram can get ruptured. When that happens, pumping the bulb just sends fuel into the crankcase through the hole, and not to the carb. You need to replace the diaphram.

My local boat shop has the pump for $97.00 or the diaphram kit for $30. Is the diaphram kit capable of providing long lasting results or should I buy the new pump?
Marine Mechanic: Captain Dave, Marine Mechanic replied 13 years ago
It really depends on your mechanical skills. If you feel confident in removing the pump, disassembing it, and reassembling with the new parts then it should be just as reliable as a new pump. If you have doubts, then I would just go for the new pump and save the time and aggrevation.
