So you would get</div><div>less thrust in reverse because of this. I am not sure whether the prop is as</div><div>efficient in reverse as it is forward.</div><div>It makes sense to orient it so that reverse is used least. However unless you </div><div>are going to be positively buoyant you would be using it the same amount</div><div>in both directions.</div><div>Orientation might be dictated by where you can mount it, as it would be a </div><div>foot higher or lower depending on the rotation. Do you want to keep it slightly</div><div>further away from the bottom to avoid stirring sediment or entanglement,</div><div>or further under the water so you can thrust down sooner when descending.</div><div>Am also interested in what peoples preferences are here.</div><div>Thanks for the Nuytco post. Wonder how big that tank is. It must be small</div><div>enough to be transported.</div><div>Alan</div><div><br></div><div><br>On 10/08/2018, at 12:34 PM, Jon Wallace via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:16px"><div id="yui_3_16_0_ym19_1_1533860912159_2693"><br></div><div id="yui_3_16_0_ym19_1_1533860912159_2694">For those of you using fixed thrusters for vertical diving and ascent, I am curious if you orient the normally "forward" thrust to propel your vessel upwards or downwards. My assumption is that there is less thrust produced in the "reverse" direction of a minn-kota than the "forward" direction. I have been thinking that I probably want to orient my motors to produce maximum thrust for surfacing rather than diving, but not sure it matters.
