Hello could someone help me identify which merc lower unit I have? It' a 1998 90ELPTO serial#OG664483. I'm trying to figure out what it is so I can buy the right tools for a rebuild project. ie:Alpha,Bravo or somewhere in between.Thank you in advance for your help.

Re: Lower unit identification.

It the inline "metric" unit as us techs call it, If you going to rebuild it it your going to spend a ton on special tools. What all are you going to do to it?

Re: Lower unit identification.

It needs a forward gear and pinion. as well as the bearing on the driveshaft.Everything else seems to be intact.Someone hit something I think and it shredded the forward gear.I have just about everything except for the pinion height shimming tool.When I reassemble the unit I just would like to make sure its all in spec. Merc is pretty proud of their special tools I know, but I think seirra makes an aftermarket don't they?I know you said it woul ruin the forward bearing to pull it off the gear right? Thanks for all your insight Fazt.
