my new(new to me) boat keeps tripping the bilge breaker. heres what its doing. the breaker is 5 amps. it was working. now it stopped. if i reset the breaker it starts up for like a half of a second and it trips again. same thing every time. it pushes water out for that quick second. the guy i bought the boat from had problems and recently replaced the breaker. what should i do first? does it sound like its the breaker. i took the pump out and it spins by hand. should i replace pump? replace breaker? could it be the float switch(separate). its a rule 1100 pump. boat is a 2002 boston whaler 255 conquest. any help would be great. thanks
