Not straight forward thing to do. You must be cautious of the brushes, and if you have MDI/MSI it can be tricky. You have to remove the spring tension on the brushes. the wires travel in a clip that protects them before they go up the shaft. Not real easy to put slack in when you trying to replace the armature. May be best to bring to an ASC. they should have experience in doing this.
if you havnt bought the armature yet they are very easily straightened by any decent machine shop, takes about 10 minutes
Be mindful of the washer and shaft spacer in nose piece.
Use a (slow) push from top then pull from bottom on the wires.. won't take much slack to clear the rear section.
Place motor shaft in a good bench vise -- those 36 volt magnets are strong.

Took your guys advice...called the ASC close to me he said leave it on the boat and bring it over this am. Took him 40 minutes and its already done! Thanks guys
Be Glad you have one close by.. nearest one to me is 5 hours away.
when you see this on the water stop and say hi.
Was covered under what was left of my warranty....it ends real soon. But if I was to be charged it was going to be 142.00 in parts and 50.00 to install it.
