Hey, it occurred to me after posting my last reply that you may not need to disassemble the lower unit to do what you want. Have you tried just pressure testing the lower unit? You should be able to pressurize it & see if it holds the pressure. Don't quote me on this, but I think 10-15 PSI is all you need to test the seals. If it holds any length of time, the seals are ok. Just don't pump them up to some ridiculous pressure & blow the seals! Here again is a video from Danger Marine showing the process....I need to check the seals.Thank you
