Removing Bow Thruster for maintenance

[Sailing Drummer]

I hope this is the right forum for this.

I'm having trouble with my bow thruster and I hope someone can point me in the right direction (just realized what I wrote - no pun intended). I'm going to also post this on another forum.

Here's the situation. The thruster fitted on my Moody 425 is a Rheinstrom. I am trying to remove it so I can have it rebuilt. The problem is I cannot separate it from the piece it is bolted to. I have removed the nuts off of the bolts but the thruster will not budge. I've tried PB Blaster. I've tried tapping on it to loosen it up. I even tried to use a scraper to wedge between the 2 parts and it won't budge! The picture is of the joint I'm trying to separate.

Am I missing something or is it simply "stuck". Any help would be appreciated.

Thanks, Larry
