started getting the boat ready for this season today, while draining the outdrive a small amount of water trickled out first b4 the oil.could it have been condensation from the winter ?
second question would be,I want to check the seals while there is no oil in it so how much pressure should i test the drive at. and how long should it hold.

You don't say what drive you have. This is for the SX

Attach a vacuum tester to oil level hole,and pull vacuum to 3-5 inches of mercury (10-16,8 kPa). Rotate
propeller and universal joint shaft to check sealing. If drive does not hold vacuum, apply a heavy oil to seal and gasket surfaces to find source. Make necessary repairs then repeat test. No loss of
vacuum should occur on low test.
If vacuum loss is not indicated, increase vacuum to 14-16 inches
of mercury (47-54 kPa). Again, apply heavy oil to find source if
drive will not hold vacuum. Make repairs as necessary and repeat
test. Drive must not loose more than 1 inch of mercury (3,4 kPa)
in 3 minutes.

Pressure test
Attach a pressure tester (such as a Stevens S-34) to the oil level
hole, and pressurize drive to 3-5 PSI (20,7-34,5 kPa). Rotate propeller
shaft and Universal Joint shaft to check sealing. If pressure
loss is indicated, use a soapy water solution or submerge drive in
water to find source. Make necessary repairs then repeat test.

If pressure loss is not indicated, increase pressure to 16-18 PSI
(110-124 kPa). Again, use a soapy water solution or submerge in
water to find source if drive looses pressure. Make repairs as necessary
and repeat test. Drive must hold pressure before making
vacuum test, and must not loose more than 1 PSI (6,9 kPa) in 3
minutes.

Do not fill sterndrive with oil until it passes both pressure and vacuum
tests.

Thanks for the info . ll try it this weekend
