Hey all,
I purchased a 1993 Maxum 1800SR a year back with a cracked block. Ending up finding a donor motor replacement. Cracked block was a 92-93 Mercruiser 4.3 (S/N: 0D841216), replacing with another 4.3 but a little newer 93-95 (S/N: 0F438375).
When installing the newer motor, I noticed the Gear Oil Reservoir that I don't believe my previous motor had. I've ended up pulling the motor out again due to some bellow issues but would like to install the Gear Oil Reservoir line. Unless I'm blind, I don't think the boat currently has it. There does seem to be a line running on my Alpha 1 Gen 2 outdrive. I've read somewhere that this reservoir was an option on some older boats?
Here's a photo, can anyone point it out to me or where it should be? There seems to be a brass plug next to the water pick-up line that I'm thinking might be it?
BTW, I know one of the crush washers fell off, I'll make sure this gets reinstalled before putting the motor back in.
