Compression 1987 50hp

Re: Compression

I have not taken compression readings yet. I need to purchase a compression tester and want to make sure that the compression tester covers the correct compression range for this motor. I don't have the manual. Thanks
 
Re: Compression

I have a 88 and 89 50hp and they are both healthy and right around 125psi, most any tester from an auto parts store will give you a pretty good idea what shape your motor is in. It's best to test it after running, while it's still warm, don't forget to pull the safety lanyard which will kill the ignition, protecting your cdi.
