I am having a problem getting my 500ho started. I took off the left side crankcase cover and replaced all of the water pump internals and after I filled up the antifreeze and oil I tried starting it to check for leaks and all it would do is click. I have replaced the starter solenoid and the starter motor and still nothing but a click. I really need help and am lost at what i could have done. It ran before i did any of this work and it did have a little problem starting before too but eventually started right up.
