Good morning! I am in search of a trim pump valve for a early 90's mercury 50hp outboard. The part number is 45197A2 and there doesnt seem to be much info out there for a replacement. I have found a thread on this forum that was started last year and I hope there may be an answer!

one reply stated there was a whole replacement cheaper on ebay but I cant seem to find that item number anymore. If anyone knows where I can find the original parts or even a newer model that will hook up and work please let me know

Thanks for any and all information from yall.
