motor were down for 24 to 48hrs,pickeled then ran for about an hour. Had to go out of town, upon returning 5 days later checked on motors seemed OK ,ran for an hour or so ,seem OK (idle was a little low ) stopped. Sat for Roughly 4hrs cranked back up with in 10mins running at high RPM on motor started to bog down, shut off & 1 piston had sezied up. Had motor taked apart for ins. and all looks good. No carbon build-up , whole motor was very clean as expected with well maintained low hour motor. But what was discovered was oil was not replaced in storage tanks(seemed OK) and has water. And noticed water in motor mounted oil tanks.
Figured after a little run time the motor mounted tank started to pull from the storage tanks and now water in motor tanks( about 1/2 inch at the bottom). Insurance does not believe this is was the problem. Only stated that it is from wear and tear not water in oil because all other cylinders show no problem.Could there be another reason.
water in throttle body
clogged carbs.
rings rusted
The piston was almost round, top ring gone. After lock up removed all metal I could from cylinder (figured motor had to have more problems)while waiting on Insurance. After a while motor was turning free so I tried to crank it up and to my surprise in cranked. Eased it out of dock and dogged motor for at least an hour(not knowing about water in oil)other than a low Rpm seemed to run OK.
