Yes, an 801. I should have mentioned it. I have two of the removable 30V batteries for 801. Dan

> That looks like an 801. Are you using 24 volt battery setup. If so you may be only getting 560 watts rather than the rated 700. You should be able to achieve the higher power and spiin the prop at higher rpm's by adding a 6 volt battery. That will get you up to the 30 volts that the lipo battery puts out. I checked with Torqeedo several years ago about going to 36 volts and they said no but that 30 was okay. Put the battery in place of the grandkids! Go faster with less fun!

So, I built a hull extension to turn it into a displacement boat. It adds about 3' to the waterline length and improves trim since it provides some much needed buoyancy aft.
