Re: Bow Thruster Siezed

Eric Freedman


When you eventually get the thruster apart,. I would suggest you take the motor to a rebuild shop. . There is an open roller bearing at the bottom of the motor where the tube enters the motor. I would bet you that that bearing is also terribly rusted and needs replacing. I would have the motor gone over while you have it out.


About every 8 months I drop the bow thruster enough to grease the spline on the bow thruster and put a bunch of grease up into the receptacle for the spline.

18 years and it drops out like a cannon ball.


In addition you can replace the lip seal and donuts that are inside the boat if it looks like it need it.

Hi Ellen,
In addition to what you're doing and Bill Rouse's suggestions (sans Amel tool) I was finally successful by using a chain wrench around the motor flange along with a 2' extension pipe for added leverage. I would torque it in one direction and apply as much force as I thought it would take. Then I'd reverse it and twist the opposite direction. After several repetitions it finally budged just a fraction. After more back and forth repetitions and it came free. I used that technique on mine and also another Santorin - worked very well.
Good luck with it!  Craig
