    Common sense would indicate that the least drag would be a pickup behind and above the prop. There will still be a de minimis. amount of drag, as the prop's rooster tail would in effect be "pushing" against the pickup, but it will be minimal. If you position the pickup above the prop to capture the vertically-rising portion of the rooster tail, you may actually get a vertical component of force, producing some lift. This is probably so small, you would never notice it, but it is there nonetheless.

      I wouldn't have even realized regarding the lift! Thanks for the input. Considering the overall weight is being kept to a minimum, it may make more of a difference than with other similar setups.

      What's all this talk about common sense? I'm not sure I know what that is or for that matter, what gravity is either. If I can "charge" the hull, then effectively, I can create a slipstream of electrons to reduce drag. I think the color would be aquamarine if you know what I mean and follow that stuff. LOL

        I guess I'm not funny. Oh well, its not the first time that I'm not funny and won't be the last.

        I'm thinking how to execute the prop wash water pickup, but I'm not a fan of how this typically looks. Does anyone have a streamlined design they wouldn't mind sharing?

          ?

          A little brass pipe out the back of the boat IS "streamlined".

            I just didn't know if someone had some fancy design they were employing for this style pickup.

              OK, here's the update:

              Tub - Shape is done and needs covering with material
              Sponsons - Need to be drilled and aligned at the correct angle
              Batteries - I have qty. 2 - 2s lipos to be run in series, so = 4s
              Motor - For now, I'm going with the Ammo 28-45-2700 I have. I'll probably take Dr. Jet up on his offer later, but that's TBD
              Strut and Rudder Hardware - In hand and ready to go on
              Driveline - Ready to go in, coupler ready
              Turn Fin - Refer to other thread: http://forums.offshoreelectrics.com/...ead.php?t=5912 - user: "westbeach" is helping me out with that, you got to love this forum!

              Motor Mount - need to pickup
              Water Jacket for Motor - need to pickup
              Prop - need to pickup and get S/B
              Adjustable Sponson Mount - need to fabricate

              So there's the update. I'm hoping that I will get some time next week to start checking off the list for assembly.

                This was a Micro Iceberg. The prop is an X427.

                  I'll keep that in mind, thanks Dr. Jet. Right now, I'm leaning towards a 3-blader. But, I admit I don't have near the experience as others, so I'm going to let the more seasoned guys in the club help to steer me in the right direction.

                  What's the worst that could happen? I get an extra prop or two in the prop box? And before you get any ideas, my prop box consists of 4 sections, overall size measuring roughly 2" x 2" x 1"! LMAO

                    OK, I'm back to motor options. I'm thinking about an 1107/2D, 2s2p at 7400mah. What do you guys think? Also, I can't seem to find the amp rating for this motor. Input anyone? Am I way off base?

                          Thanks for the link Jan. Thing is, I don't see this motor. Am I missing something?

                              Cool! It looks like I'm not too far off then. Unless...

                              What do you think for this build, keeping in mind it is ultralight?
