    Moving right along! Good job. Can’t wait to see the results of your first splash tests. Keep the build updates coming.

        Rob, those cylinders are designed for 3S LiPos. Everything will still work, but the pump in particular has an in-line resistor to drop voltage from the expected 11.1 to 6V. The pump will still spin, but you may find that it's sluggish. If you're dead-set on the 2S battery, you can remove the resistor, or you can just get an 11.1V battery.

          Ok Bob! Thanks for the heads up on the pump situation and battery size. I have a 11.1 volt 3 cell 30c 4000 mAh that will fit!

          I do have another question?



          In the above photo, it shows the ballast system items that are not being used now that my boat will go direct as a snorkel system.

          Can I just eliminate that system? That piece on top is leaking from the valve itself as well and the part with the two screws!

            Piccy no show, but with SNORT, you only need a hose going up to the surface and that's it. The snorkel valve and the safety valve are all superfluous.

            SNORT is absolutely my preferred setup for virtually all boats. Stationary diving is for ballistic missile subs and research subs.

                David and Bob, Thank you for answering my question! I sure do like the simplicity of the snort system!
