1990 120hp L-Drive
A few months back I was on the river. I just got the boat on plane and then 5 seconds later it lost power. The boat would run, but only at 1/3 - 1/2 power. I limped it back to the dock, took it home and let it sit until now.
I started simple with a compression check. Cylinder 1 (top one) 135lbs, cylinder 2 133lbs, cylinder 3 127lbs and cylinder 4..... 0lbs. So off came the head and here's what I saw
Not good!
I found some shavings in cylinder 3, but it surprisingly read 127lbs on the compression test. Not sure if the cylinder is trashed. Cylinder 4 is mega-trashed.... not even sure if it can be bored enough to rid of those gouges.
Please speculate as to the cause and requirements for repairing. Is cylinder #4 going to require a sleeve? Do the spatter marks on the head render it useless?
Also, where can I get replacement motor parts for the best price?
Thank you!
