Hey All,
New user here and thanks to the help from this forum I was able to diagnose my engine cut out issues. Turns out, my 4.3 MPI has the engine cutout issues that plague some older MPI engines. More details on the following posts if interested:

My question is, I have bypassed my shift interrupter switch in order to solve the problem. According to the above bulletin, the proposed fix by Mercury is to shell out over $2000 for a new ECM.
Since my boat is running fine using the bypass, I thought I'd ask the forum what could happen if I continue to run it with the shift interrupter switch bypassed? Any possibility for damage to the shift cable or gears?
If there is a compelling reason not to keep this fix long term, are there any alternatives to getting a new ECM? Could I get it reflashed with new software instead?
