"i have a 1966 120hp OMC stern
"i have a 1966 120hp OMC stern drive with a chevy 153 inborad engine. the motor runs fine, i bought the boat for 300 bucks and it had obviouly been sitting out in the weather for a while. it took me about an hour to get it started, as well as new plugs, cap and rotor and cables.
once it fired up, it ran strong, sounded good. put the prop in a tub of water to check the cooling system and everyting was good. let it run for about an hour and a half at idle and throttled it up a bit to see how she ran.
after the tub test, i checked the oil and it was fine, no leaks that i couild see. I took it to the lake later that day, ran it for about an hour at all throttle ranges. when i stopped back at the dock, i did another oil check to be sure i wasnt losing oil and it was milky!
i quikly took the boat home, pulled the oil plug, drained it, changed it, and got a new filter. put it back in the tub of water to see if i could isolate the leak, but to my suprise.. after 2 hours of running in the tub of water. there was NO WATER in the oil.
so... another lake test. took her back out. took it out of dock, throttled it up for aobut 2 min, turned the motor off, pulled the dip stick and sure enough, there was water in it!
help!! i dont know why it leaks water into the oil at the lake but not when i run it at home. i have the entire prop and water intake submerged at home in the tub.. what changes in the lake?
any help would be great, i am at a loss.. this is my first boat. i am an engine wiz, but the stern drive is all greek to me. what am i missing?
thanks!"
