I had a boat given to me (Cruisers inc. 19' Tri-Hull to be refurbished) along with a 70HP Chrysler motor. I had the motor in a homemade tank for testing purposes. After a week or so in the tank and running it several times I noticed a bit of oil floating on the water. I know this is normal but at the waterline there seemed to be a quite a heavy build up of a heavy grease like oil sedement.<br /><br />I drained the tank, cleaned off the motor and drained the oil from the lower unit. The oil in the lower unit was rather thick and it was of a beige cream color.<br /><br />I've read in different posts that this means there's water getting into the lower unit. I also read in one post that synthetic oil has a tendency to turn this color. I've poured some oil into a glass jar. If there is water present, shouldn't the water and oil separate?<br /><br />I also noticed that the drain/fill plug and the oil level plug were very easy to remove with a screw driver with very little effort.<br /><br />I was thinking of refilling the lower unit, changing the gaskets on the plugs and tightening the two plugs (more than they were) and trying it again.<br /><br />Being new to boating would this be a good start before I tear apart the lower unit and change the seals? Would this be a good start in the process of elimination?<br /><br />Any input would be much appreciated.<br /><br />Thanks,<br /><br />Dymo
