Anybody out there done it or similar and have wisdom for me? I began trying to fix my old motor when it suddenly wouldn't crank after I replaced the motor mounts due to excessive vibration only in forward gear. Also ran rydlyme throuogh engine for 3 hours with a transfer pump. Mechanic says exhaust was plugged and raw water has been getting in cylinders for some time. After exhaust manifold was remachined for almost what a new one would cost, I got news that complete valve job would be next to the tune of another $1400. Then we'd be able to see if cylinders would make enough compression to get me by for a while. I pulled the plug and said enough. Thanks for any help.
We've been thru this as well.. Who was you mechanic and which marina?
