Quick help need for lower unit 20hp mariner

[theshoaibahmed]

Hi all friends i wanted to service water pump and but after taking 4 bolt out (2 left and 2 right) i cant take the lower unit out. Seems something stuck. I tried pulling harder but didnt want to put to much force. Can of the friend tell me is there any screw or something which is causing lower unit not to come down.

Some motors have a 5th bolt up under the zinc anode trim fin.....look for a plastic cover that pops off with a bolt down in there to remove trim fin, then up under that fin another bolt....
