0. It probably is not gear oil on the water. It would take a major leak to do that, and you wouldn't have to be pressure testing it to find that big of a leak. It is the oil that you put in the gas. Every drop of that oil passes through the engine. Some of it is burned (smoke), but most of it goes out the under water exhaust---right into your test tank. That's just the way it is.

1. Remove the lower unit, and water pump, drain the oil out and pressurize with 3 or 4 pounds of air, max. Observe air leaks.

2. Remove the powerhead, disconnect the shift rod, unbolt and remove the lower unit.

3. Absolutely. The lower unit parts are the same as Evinrudes and Johnsons. Most but not all of the upper parts are also.

Thanks for the reply

The slick of oil that is there in my test tank is a creamy white color.
The oil that is in the lower unit looks to be the same.
how would i know if water is getting into the lower unit?


Thank You again

If the lower unit oil is creamy white color, it IS getting water in the lower unit. Time for inspection / seal kit.

I have a Sea King 5hp I'm trying to get going and the oil in my water is very dark.
