Re: Checking out pre alpha w/o disassembling
hum, well, you could do a pressure test of it to see if it holds pressure and vacuum. this would test the internal seals. from the diy sticky at the top of the i/o forum page....

you could check the gear ratio to be sure it's what you need.. from someone elses post on how to check that.
"How do I check gear drive ratio?
Do all these steps in order.
1. Shut off the battery switch
2. Pull the spark plugs out of the engine.
3. Put the shifter in forward.
4. Turn the engine till the prop starts turning, continue turning till the timing mark is at TDC.
5. Put a mark on the prop hub and the drive housing that align with each other.
6. Turn the engine by hand while someone watches the marks on the prop, and count the revolutions the crankshaft makes to turn the prop 1 complete revolution.
7. If it took 1.5 revolutions of the crankshaft, then you have a drive ratio of 1.5:1 which is what is needed for a small block V8. (a 260)."
yer gonna have to replace the impeller anyways, so you can check for seal wear on the lower drive shaft.
you can check to see if it shifts.
fwd= prop locks ccw
neutral= prop freewheels
rev= prop locks cw
when you drain the fluid out of it. you can check for water intrusion and feel the first drops that come out when draining the drive. feel for metal fragments.
you can inspect the drive shaft for spline wear.
you can check the ujoints.
best i can come up with so far w/o disassembly..
