Anyone know what psi reading I should expect on these 1988 200's?
On a new engine?
An engine that I probably don't want?

I have a couple of '84 150's. One I rebuilt in 2000 and
the other has had no major work. These are basically
the same as the 200 with a different carb.

They both run like tops. I baby them and inspect regularly.
The biggest problem is rust. These were manuf. before the Sal****er
Series and Im afraid the power heads are going to outlast
the Tilt/Trims, Shift rod, Steering arm, lower unit, etc..

Pull the props and inspect the large keeper (thrust?) ring
just inside the lower unit. This ring has a tendancy to
corrode in-place and crack the lower unit. I had to weld
one of my lower units' oil case shut.

I can find no mention of proper compression in any Yamaha manual
for these puppies other than they should all be within a few psi and
mine are. The rebuild being slightly higher of course.

I would guess they are worth somewhere in the neighborhood
of $1000 - $1500 ea.

Oh yea...

Do loosen and and re-tighten the lower unit bolts occasionally.

Enjoy!

db~that reminds me, Its about time to start thinking about de-winterizing
and
spring inspection.
