    The bow thruster on my 2003 270 Sundeck didn't work when I bought this boat from the 2nd owner. He claimed it hasn't worked for several years and he never bothered to fix it.

    Most people I have asked about it say "oh you don't need to use that on a 27' boat". The fact is that it came as OEM equipment and I like to have everything with a factory switch working.

    I haven't done any troubleshooting on it as yet but was wondering if anyone would know what brand it is in case I can find a good deal on one online or elsewhere?

    If not, how can I tell or where would I look to confirm the brand?

    Thx.

    Sorry I looked at the control and it says Sidepower st the top and Sleipner at the bottom.

    I guess what I am trying to find out is what size thruster or horsepower/model is the correct replacement unit? Thx.

    To answer the question why it is not working.....Check to see if you have power to it. If not check the fuse and the wiring. If you have power....then the motor might be the problem.

    Great stuff. Thanks!

    Also, my boat stays on a trailer when not being used but if I remove the thruster for repairs and want to still use the boat is there a block off plate or something that I can bolt in the space?

    Actually, you should be able to remove the motor from inside the boat. It connects to a water tight gear system that turns the propeller in the tunnel. Removing the motor will not cause a leak unless something else is seriously wrong.

    Before you pull it....test it. Oftentimes it is something that got stuck in the propeller that caused the main Thruster (250 amp) fuse to blow. Check to see if you have power at the motor when the control is switched on. You turn it on by depressing the two ON ON buttons simultaneously on the joystick. A small yellow led will light. If that does not come on....then you need to check the fuse that feeds the joystick (5 or 10 amp).

    Before going the motor route make sure that battery is good (my bowthruster has a separate battery) make sure the battery solenoid works, make sure the control switches work (I have two switches: a master solenoid switch and control switch). While the motor could certainly be bad or the prop jammed up I would think it is more likely one of the other components which would be easy to test before pulling the motor. Oh - and check for any other breakers that may need to be reset.
