Greetings,
After much consideration, reading these forums, and talking to the boss (A.K.A. the wife), i've decided to turn a boat anchor into a running motor. i have a 72 johnson 65ESL72S that looks like it's going to need a powerhead rebuild and has the typical shifting problems in the lower unit. I hope this simple newbie to boat motors can call on the masters of this forum for help and advise as i go along.
Lower end.
Ok, i changed the oil in the lower end using type C oil. Oil that came out of it was black, but no signs of water or metal in the drip pan. Unit is stuck in forward, even after running the motor for 5-10 minutes to see if it would pop into neutral while warming the engine to do an compression test. Following the guidelines layed out in this forum, i've applied 12v directly to the solinoids. no change, but the question i have is, does the motor need to be running while doing this or can you just be turnng it over? I've done the dc amp test, ohmmeter test, the shift toggle switch and the neutral switch test all pass. only other wierd thing i find is without running a jumper from the battery to the knife for the 12v, i only read 10.2 vdc. Any help or advice would definatly be welcome.
Powerhead.
The for mentioned compression test didn't come out too well. The motor will run, compression though is 30, 90,90 from top to bottom. I know this motor sat for quite awhile, and now it seems like its toast. I do have an OEM service manual, and i'm ready to jump in with both feet. Any advice or thoughts on this before i start? Like i said, this will take some time, no rush, Minnesota winters are just too damm cold at times to work in the garage, but i will keep at it.
Looking forward to hearing from you all
