alpha 1 mercruiser lower end unit oil

[navymike]

good morning,
i have a 1989 invader (171 bowrider with 3.0 mercruiser(130hp)alpha one outdrive. My question is im wanting to change the lower unit oil i understand how to do it but my concern is do these year model boats come with a external reservoir on the block or off of it to fill up as well. i have searched all over and havent found one the only one i found was for the trim motor. i just want to make sure im not over looking anything. another question is there any free manuals to download for servicing? outdrive sn:0C827349

Here's the factory service manual for your drive Manual#6.

can't download it but can thumb thru it and print pages if necessary...

Alpha One's didn't have the external reservoir, the Alpha One Gen's 2's do.

I have seen the newer model ones that have the external one when i watched videos of how to change it but like i said i wasnt sure if mine had one and i was over looking it. thanks for the info
