I believe that if you carefully go through this email, your problems will be solved.
I have several suggestions after reading all of your postings. I noted that after one of the seal changes everything worked fine for a year, that would lead me to believe that something is different. But, I also have unanswered questions. Let me ask the questions first:
I believe your issue could be caused by in order of probability:
I believe with a high degree of certainty that your issue is 1 or more of the 4 above, and based on what you said, I am 100% positive that your bow is too low.
Modifications, including different materials, changed specifications, and/or devices installed to overcome any or all of the issues above are not recommended and you should systematically go through 1-4 above and rectify all problems found.
If I am correct regarding the bow being too low, I recommended that after correcting this, and at the earliest possible date, that you separate the motor from the tube and inspect that area and the bearing in the motor. It will be full of rust and corrosion. Clean it well and use a generous amount of waterproof grease when you reassemble....if not, it will become stuck, worse, the motor bearing will collapse. Also, an interval of 2 years is appropriate for bow thruster service.
