Help with 2009 Stealth Patriot Motor

[Stealthowner09]

I recently bought a 2009 Stealth Patriot. I replaced all the batteries and it was making a loud noise. I replaced the motor with my other stealth motor and the noise stopped. I know it was used by the previous owner to pull a boat in and out of water and it had a LOT of rust in the transaxle when I took the motor off. I have been trying for days to pull apart the 4x4 motor to clean inside it and get the funk out. I cannot figure out how to get the motor apart. I have taken out all screws. Pushed. Pulled. Everything. What am I doing wrong? Please help me get the motor apart. Any help at all would be great. It did not come with a manual. I have found several videos online after people have it pulled apart but not showing how.

Also the Previous owner put silicone on the motor to help prevent the water from getting in it. It did not help.
