Did you test the old vts motor? From what I read it’s the vts module most of the time, There is also a 7.5 amp fuse somewhere for the vts. I’m pretty sure the magnets are to stop the screw drive from going to far and a missing magnet shouldn’t stop it from going up. I have done a little research into it as I have a couple machines that need vts fixed. I’ve seen a fix that uses a 451M relay to replace the module with. You could try searching that if it does end up being your module, also there is a boot that keeps water out of the vts box, I guess they are known to tear and leak, so something else to look into. If you search and want to search seadoo forum, enter your search in google like this vts 451M relay fix site:seadoo forum.com good luck
