Bow thruster

I want to install a bow thruster on my 39' FB sedan but am very hesitant about installing an FRP tunnel in an aluminum hull because of potential un-bonding problems. Is it possible to mate a Lewmar bow thruster, for example, to an aluminum tunnel tube? Also, being somewhat lighter and shallower draft than a typical 40 footer, would a small thruster, say 3 hp, do the job?

You might want to ask Lewmar. Personally I'd check with a couple of suppliers to decide who was making the most sense.
Good luck.

Depending on your needs, would a stern thruster work instead? No tunnel to cut, just a few bolt holes under the swim platform instead. I know that is an over-simplification but, they do offer an alternative to cutting a hole in the bow.
Best of luck, Scott

Looking at the Lewmar website, it looks like the tunnel is not specific to the thruster. A call is best to Lewmar, but looks like the install would fit on an aluminum tunnel.

Here is a Vetus that gives tunnel choices as an example.
