More information would be good, I`m considering installing an Exturn next haul out.
Any photos of it installed? Was it difficult to attach, does it require fiberglass work to create a base for it? Did you need to add any battery(I`m hoping to use the windlass power supply)? What wattage does it draw? Any discernible effect on performance/speed? Anything else you can pass on from the experience?
Hi, Bruce,
I'll get photos uploaded this afternoon from the home computer.
The install was very easy; it took more time to plan the electrical layout and control layout than to do the actual install.
We started the external thruster install on a Friday afternoon, and were completed by Saturday afternoon. This time included the drilling of the mounting holes, priming and painting of the unit, hanging the relays, and the physical installation of the thruster itself. I installed the Duplex model, so there were 2 2" main holes and 4 3/4" stabilizing holes drilled into the hull bottom.
For the electrical side, I installed 2 Optima AGM Bluetop batteries, a dedicated 12V charger, the thruster fuses, and power shutoff switch under the forward bunk. I did the electrical side of the install just before we hauled out, while the boat was afloat. This part of the install took about 3 hours.
We've had the boat out several times, and there is no difference in handling or speed I've noticed. The thruster is placed at the forefoot of the boat, and does not cavitate when in use. The thruster is quiet, and pushes the boat in a controlled manner. It is very effective in windy situations.
Install tips- Exturn/Yacht Thruster recommended that I plan the install in detail before hauling, and have wiring pre-cut with end lugs installed. I did so, and it made all the difference in the ease of installation. I used 2/0 wire for all power connection, with all lugs crimped and shrink-wrapped. Otherwise, the Exturn installation instructions are pretty straightforward.
