No sweat, I really funny story before I go pass out, I mean go to sleep...
Had a guy bring a jetboat in to me when I had my shop (probably 1997), he said the engine siezed up and wanted to put in a ZZ454 from GMPP (cost like $5,000) and I could have the origional BBC as a core, I asked him if he wanted me to troubleshoot the failure and he said no, so I pulled the motor and put it on the ground in the back of the shop, ordered up a crate motor, switched over the marine parts, and could not get the engine to turn over, turns out there was about 100' of nylon rope wrapped around the pump shaft, it completely filled the intake section, I had to cut it out with a die grinder and filled a medium sized garbage can, I called him and told him what I had found and he thought I was screwing with him...Needless to say there was nothing wrong with his origional motor, which turned out to be an LS7, I still have it, runs like a top....
