2000 Mercury 225 EFI Lower unit gear question

[skidog519]

I had to remove my lower unit and had a seal job done on the lower and after i put it back on the upper I am checking to see if I have the right movement in my propeller before I put it in the water to make sure the linkage is all working as it should.

I dont think it is working right, here is what I have.

When gear selecter is in forward it only moves about 1/10 each way counter clockwise and clockwise and then it is locked. ( Is this correct? I thought it forward it should not mover counter clockwise but should move rather easily clockwise. )

When gear selecter is in neutral it moves freely each way counter clockwise and clockwise 360 degrees

When gear selecter is in reverse it only moves about 1/10 each way counter clockwise and clockwise and then it is locked the same as it does in forward.

I removed the lower unit again and messed with the lower linkage selecter. It apprears to have three positions as would make sense forward, neutral and reverse. The same thing happens as above when it is put back together or removed by itself when I try and move the propeller by hand i get the same results.

Thoughts?

Do you have the s/n of your engine and I will see if I can get you the online manual.

The test for that engine is by rotating the flywheel for N and R, not the prop:

FWD: Rotate flywheel CW and note that prop turns CW

Neutral: Prop will turn freely either direction

REV: Rotate flywheel CW and note that prop turns CCW

All flywheel rotations as viewed from above.

Thanks Gerry for all the information. Why would the serial # and year come up differently? It is a rebbuilt motor I purchased last fall and thats what is on the invoice, or does it just fall in that range?

I get the information from Mercury and other sites and was surprised when this one came up as a '97 after reading that you thought yours was a 2000? When you say that the engine was rebuilt, do you know if the powerhead was replaced or overhauled?

If it was a 2000 year, the s/ns would be in the OT range, not OG

Interesting, no I am not sure on the powerhead, I will find out from the company I bought it from. Where is the serial # located I will double check it on the motor
