Pair 3208 TA 375hp marine w T.D. gears w 2:1

1 engine has 3500 hours and the other has about 1000 hours. Engines ran good when taken out of boat to repower.

Engines were stored in a barn.  Went to do a test run of each for purchase and one engine was discovered to be stuck.  They took the plug out to pre-lube it, and discovered water.    The other engine was pre-lubed and ran without issue.
