Tell me a little about gearcase pressure and vacuum.

Sound like a lot of money you will be laying out here.

If you can, take them in and have the basic checks done on them, visual,
compression, spark, gearcase pressure and vacuum, test run, et al.... It
may
cost you a few bucks, but these checks could save you a lot of hassle and
cost down the road.

Secondly, don't trust what the other person is telling you. He might not
even know there might be problems with these engines, as I just found out
the other day dealing with another product that was for sale. Just my
visual
inspection told me this engine had many problems. The basic checks will
tell
all.

Pressure and vacuum are tests that can be performed on the gearcase to
verify no seals are leaking. However, you have to be very careful in
performing the test or you will cause a seal to begin leaking.

I have never actually performed this test on any boat I have had.
Once you run the boat in the water for a test run, check the gearcase oil
for any water. The water will come out first as it sinks to the bottom and
the oil will look brown to milky if there is a problem.

Jim and Becky,

It's a simple test, using a hand held air pump and another hand held vacuum
pump. But it's cost prohibited to purchase both pumps, unless you are a
service technician or you do this a lot and you love doing this type of work
in your shop.

The service manual will give you the specs for pressure and vacuum tests.
Usually the pressure test is about 10 to 13 PSI and about 3 PSI for the low
pressure test on some makes and models. Again, see your service manual and
don't take my word for it 100%, as I have not got the specs handy.

But the two tests will show if you have leakage in the gear case, and it
takes just minutes to do and is well worth the small cost. And as someone
else mentioned, draining the gear case of oil and examining the drained oil
is a good way to spot problems, as a gear case that has been leaking will
often show the fluid to be a brownish "milky" color, no different than water
being in the crankcase of a car engine.

Your service shop sounds like the place for you to be, especially with the
expensive purchase you intend to make. If this fella who is selling these
products had any smarts, he would have taken these engines and the boat in
to have the checks done, and gotten a printout to show that both engines and
the boat are in sound condition. That way, he could sell you these products
and he would know that they are sound and so would you.

Don't screw around with outboard engines. Often they look good, run good,
but a lot of times, the very basic checks point out serious troubles
internally and externally. Believe me, I've seen just about all in this
regard. I am sure others on this newsgroup can relate.

I hope it works out.
