I bought a boat from a friend that had water in the bilge for several weeks. When I got it in November I was able to turn the motor by hand with a wrench on the crank bolt. After sorting some things out I went to winterize the boat to find the rings have siezed due to moisture. Ie motor won’t turn over from rust on the rings. I put marvel mystery in the cylinders hoping that would work...nada!
I don’t have time to pull the motor until spring. How can I get coolant through the motor without running it? Or drain any water that may be in the block, etc.
TIA
