What all did you do for the 125 hour service? I just did my oil, tranny, V-drive and fuel filter the other day. I change my oil about every 50 hours and impeller every 100 at least. I took a few pics and planned on doing some type of quick write up but never got around to it. The fluids I got from Larson Marine and they are:
oil: Mercruiser fully synthetic SAE 20w-40
Tranny: Formula shell multi-vehicle
V-drive- Shell Rotella T heavy duty SAE30
I use the Moeller pump as well and it worked great. I'll attach a few pics from the fluid changes.
