<div dir="ltr">Hi Dave,<div><br></div><div>Looking good! Surely there is a 11" diameter hole coming in the bottom of that tunnel? You wouldn't want to draw water in horizontally and expel it vertically - you'd want it to come in directly from the bottom and go out the top. And once you had that hole, the thruster maybe could also go a little lower, so that the prop was just below grade on the top skin. But the latter suggestion seems to me much less important than the first.</div><div><br></div><div>Best,</div><div>Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jul 4, 2020 at 1:47 PM David Colombo via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="auto">Ok guys, looking for comments on potential issues with vertical thrusters. This morning I laid in the first vert thruster in the wing to mock up the attaching bracket to the hull. The twelve inch hole will go thru the wing. The questions are:</div><div dir="auto">1) hold the prop flush with top surface or raised slightly. I will be fabbing a grill cover.</div><div dir="auto">2) as the prop can draw water from the bottom as well as thru the thruster tube, any concerns with prop wash being pushed out more laterally vs vertically. Wondering if i need to have a collar at least as deep as the prop?</div><div dir="auto"> You might be also wondering why I have 101 lb vertical thrusters. Never know when you might need to do a barrel roll maneuver.</div><div dir="auto">I appreciate the feedback</div><div dir="auto">David</div></div>
