One of the studs on the sterndrive is angled too much when I rethreaded it, so it's not aligning properly with the transom mount.

I just did a dry fit with the gimbal housing to the transom mount outside of the boat. I had noticed that one of the gimbal studs that I had rethreaded in the gimbal housing is angled too much causing the two parts to not match up properly.

Question: Do I re-tap the gimbal housing stud slot to get the angle ( which I don't want to do), bend the stud slightly, or hollow out the area slightly where the stud goes on the gimbal housing to make it fit , I need about approx 2 or 3 mm to make it fit properly. What would you do, your thoughts. I'll post a pic soon.

My neighbor (who is a boater and a good handyman) suggested to heat the stud with map gas while it's in the gimbal housing, put two nuts on top of the stud and hit the nuts with a hammer to get the angle. What do you think?

Oxygen/acetylene torch IMHO just because I have a set. Doubt Map torch will get stud hot enough

You'll probably break the bell housing trying to heat and bend the stud with it installed

Remove the stud, clean out/straighten the threads in the bell housing and reinstall the stud straight. If you can't get it you may need to go bigger with the hole and install a helicoil

If your new threads are strong enough ? Just file away the plate hole carefully until it slides down easily. DO NOT tighten the daylights out of the nut and stud.

if your stud is cross-threaded. the only solution is to remove it, correct the threaded hole, use a helicoil if needed.
