I have had a yamaha 30 hp out board for a few years now it is always acting up and never working right i want to try to figure it out with out paying 200 dollars at a boat shop to get it fixed. it is not pumping gas to the motor ( i think) this means i should buy new hoses. this is on a jon boat it is a tiller version. is anyone else havein problems like this and what else could be the problem to keep it from firing
