Where can I find the gear ratio of my I/O?

[fabrimacator21]

It is an Omc 800 with a 305.

I got the numbers from the tag which are

Model #: 982141

Serial#: W189291.

Is there somewhere I can run these numbers to find out what gear ratio I have?

this comment is something i saved from someone else that wanted to know the answer to the same question... this was the answer from someone..

"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)."


that should fix ya up..
