Hello. So I've been browsing this forum for the past week doing some research and learning a bit. Reason why is I had bought a 1994 Johnson 60hp VRO and was picking it up this past weekend. Prior owner stated it had low comp in 1 cylinder and would stall off and on. I picked it up last weekend and did my own comp test last night. Here are the #'s:
#1 top cylinder: 75psi
#2 middle cylinder: 112psi
#3 bottom cylinder: 112psi
The motor is missing the id tag for the model and serial, so is there any other way to find out that information? Motor is a long shaft, 3 cylinder, electric start, remote steer unit with trim and tilt. As said above, he said it was a 1994, but without knowing the model # I have no real way of telling. I am planning to get a spare tank for it today so I can get it running and see about the stalling issue. Could be due to the low comp., but want to run it and see. I peeked through the spark plug hole while doing my comp test and the piston didn't look too bad.
Oh, and first thing I noticed was the VRO has been removed, so it's a pre-mix motor now. Any help and/or suggestions on it would be appreciated. I am fine with tearing it down to rebuild since I have another motor on my boat now, so I'm in no hurry to get this one into operating condition. Just need advice and suggestions.
BTW: I did the comp test on the motor with the plugs out, carbs open, and the motor was cold since I have no gas to run it on to warm it up. Planning on doing a leak down test today.
Please check the more recent posts from 10/29/08 for updated info and questions.
