Just got into boating, purchased a boat with an 5.7 OMC Cobra. Boat sat outside and hasnt been run for 7 years, receiving help from friends who have been boating for many years but are not very familiar with OMC.
So far we changed the shift cable to the outdrive, inspected the bellows and impellar, both of which were in great shape, which surprised my experienced help. Had the carb rebuilt, changed out motor oil and filter, gear oil in outdrive. Removed all old fuel left in the fuel cell and swabbed out whatever water was in the cell also changed fuel filter. Pulled off the exhaust manifolds and risers, (they were rusty but not clogged), replaced the gaskets, soldered a few areas on the powersteering cooler that had leaks. Ran the motor on muffs, everything seems fine so far except the oil level went up about 1/4 inch, we are hoping this is just from condensation and possible fuel mix from not being able to run the engine hard yet, person I bought boat from winterized it best he knew how, however when we got it to my house there was a little water maybe a cup full from not having rodded out the drain hole, would this be enough to cause internal freeze damage?
We had put the boat in the water only to hear some drips coming from what we believe is the hose the shift cable runs through near the transom, or possibly where the "Y" part of the exhaust connection. Hard to actually see or tell. Decided to pull the boat out of the water and hold off on running it till we install a secondary bilge pump.
Any other things we may have overlooked on doing to an OMC prior to putting the boat in the water for a test run?
