Re: [Amel Yacht Owners] Do you want a spare Linear Actuator control board?

adding a fuse to the PCB on the bowthruster is quite simple. I added one to the + wire

on the pcp in a small fuse holder.

Congratulations! This is really very good news for All SM owners that have electronic sensors on their bow thrusters.


If I still owned BeBe, I would buy one today for several reasons: 1.) The PCB on BeBe #387 was NOT protected by a fuse. 2.) Sooner or later, possibly every SM will need one of these and without Amel supporting it, we have few choices.


Maybe you should think about the Amel electronic chain counter as your next project.

In an odd coincidence, I was working on a making a replacement PCB for the Bowthruster Linear Actuator before Duane made this post. I didn't want to say something about it on the forum until I actually had one completed and tested on my boat though I did reach out to Duane through an intermediary to let him know that I was already in the process of making a replacement. I finally finished the successful testing of the prototype this past weekend.

I uploaded some pics of the prototype PCB on the forums here:

And here is a link to a video of the bowthruster being lowered and raised back up using the the prototype PCB:

The PCB design mimics the original one in my SM #440 as much as possible. It has a 10 amp fuse and the traces are all sized larger than the original PCB. I used the original components wherever I could. So far I've made only the one board, but if anyone else is interested, I can readily make more within a few weeks and can offer them for sale at $250 each (plus shipping) with a 3 year warranty. You can contact me at mfmcgovern at if you are interested..

I hope this helps some of you. My next project is to attempt to make a drop in replacement for my non-functioning chain counter display unit. I expect this one will be a bit more difficult but I will let you know if and when it is done!
