Mercruiser Leak Down Test

[alldodge]

Down here in Tampa Bay there are very few cool days. We have not experienced any cool days while out and about. I believe you are right about the vapor lock issue. The next time we go out maybe it would be a good idea to run both bilge blowers a while to let some of the heat escape in the engine department after shutdown. I still would like to test each injector using my Rinda scanner but again I need to know how to get access to the injectors wire connectors.

Do the test as listed above in post 16. To start unplug all injectors except the one your testing. Turn the key on/off as indicated and record readings. To get at the injectors you may need to remove the plenum to gain access to the injector connectors.
