Compression check ????????

[PULLNIT]

I am going to compression test a 1989 Johnson 150 I am looking at.I have read all the posts on how to.They suggest grounding plug wires or pulling lanyard to prevent power pack damage.My question is does this year motor have a lanyard to stop spark?If not what do I need to buy and how do I ground spark wires. Thanks again John

Your engine should have a safety lanyard (kill switch) mounted to the dash if it's a binacle control or mounted to the control box. If you pull the lanyard out it kills the spark.

Senor Pullnit,<br />You can spin the engine without powering up the ignition stuff by jumping across the big terminals on the starter solenoid. Be sure to remove prop and engine is neutral.<br /><br />c/6<br /><br />hooty
