Re: Bow Thruster Travel Adjustment

thomas.kleman <no_reply@...>

Hey Paul- it seems like almost a two part problem......first, you want to get the pin in to create the seal. This can be done by just pulling the lift wire, lifting the thruster the remaining few millimeters to get the pin in. The second part involves the more complex task of adjusting the lift mechanism to achieve the correct height when the red indicator light indicates full lift on the unit.........personally, I have never mastered this. At one point I had it perfectly aligned but this yielded a new problem. With the holes perfectly aligned at full lift, there was no friction on the pin and in rough seas the pin actually slipped out after it was fully inserted. So I now lift it the last few millimeters by hand and insert the pin so the weight of the thruster holds the pin in place while keeping the seal firm. Bottom line, not a drop of water in the bow thruster bay. I will be anxiously reading these responses because one of the old salts always has a way to improve processes like these.

We recently serviced our bow thruster and now the unit now longer comes up high enough to insert the pin easily.  There are (what appear to be) three adjustment pots.  Two are located above the control box and one below,  Of the two above, the one to starboard is labeled “B”  the one to port is unlabeled.  The one located below the control box is labeled “H”.

Are these indeed the adjustment pots and if so, which one is used to adjust the upward stopping point.

I have searched the manual and forum and can’t seem to located the information.

Thank in advance for any and all responses.

All the best,
