Year?<br />What trim pump?<br /><br />Since you can't find how to fill the oil, I have to assume you have a Prestolite pump. The newer ones are too easy to figure out.<br />Just fill till it comes to fill plug. <br />But that is probably not your problem. What exactly is clicking????<br /><br />

Hi Don, <br />I too have that same issue, I am looking for the right fluid to put in and my res. under the pump has a filler cap, is that where I put the fluid in and do I just fill-r-up????<br />PS, don't know what pump I have, but it's on a 17 ft chris craft 87 model 3.0 ltr.

Start a new thread with your question drummer, and include what engine and drive combo you have. With the info you gave, it's impossible to answer.

what would be the right fluid to put in the resivor of the t/t? it has a cap you unscrew and just put it in.

Your solenoids have 4 terminals,two large and two small.Use a jumper wire across the two large terminals on the solenoind with the big blue wire.This will tell you that the motor is OK,and you have a bad solenoid,wiring or switch problem.That's what needs diagnosing.<br /><br />DHP<br /><br />OH Blue is up,as in sky is blue,green is down,as grass is green.
