Hi all,<br /><br />I'm looking for specs on the lower unit gear ratio for a 1985 25 HP Yamaha 2 cyl outboard, model 25LK. I'm looking at buying a used lower unit and want to make sure the ratio is the same. Looks like it will bolt up but I'd like to make sure it's the right one.<br /><br />Thanks in advance. (Yes, I know, I should get the factory service manual... will do so if I know I have enough parts to put the thing back together. 
)
