I'm also thinking that if your compensation is close to ambient as it would be with a regulator setup as you have, the orientation of the seal won't much matter since it's not holding back any significant pressure on either side.</span></div><div id="yui_3_16_0_ym19_1_1491925896129_3420"><span><br></span></div><div id="yui_3_16_0_ym19_1_1491925896129_3420"><span>Jon</span></div> <div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1491925896129_3419"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1491925896129_3381" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1491925896129_3380"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1491925896129_3379"> <div dir="ltr" id="yui_3_16_0_ym19_1_1491925896129_3418"><font size="2" face="Arial" id="yui_3_16_0_ym19_1_1491925896129_3417"> On Tuesday, April 11, 2017 11:05 AM, james cottrell via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1491925896129_3378"><div id="yiv7779207970"><div id="yui_3_16_0_ym19_1_1491925896129_3377"><div style="color:#000;background-color:#fff;font-family:verdana, helvetica, sans-serif;font-size:13px;" id="yui_3_16_0_ym19_1_1491925896129_3376"><div><span></span></div><div class="yiv7779207970qtdSeparateBR" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3301">Jon,</div><div class="yiv7779207970qtdSeparateBR" dir="ltr" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3470">I just picked that motor diagram because it was more clear than most. I'm just saying that redundant seals in trolling motors in general are probably to prevent water ingress if the outer seal is damaged- the outer seal is probably not needed for our application. Water against a single seal might be even better from a cooling standpoint.</div><div class="yiv7779207970qtdSeparateBR" dir="ltr" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3475"><br clear="none"></div><div class="yiv7779207970qtdSeparateBR" dir="ltr" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3476">Greg<br clear="none"><br clear="none"></div><div class="yiv7779207970yahoo_quoted" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3244" style="display:block;"> <div id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3243" style="font-family:verdana, helvetica, sans-serif;font-size:13px;"> <div id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3242" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div class="yiv7779207970yqt9323160441" id="yiv7779207970yqt61792"><div dir="ltr" id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3241"> <font id="yiv7779207970yui_3_16_0_ym19_1_1491921982732_3390" face="Arial" size="2"> </font></div></div></div></div></div></div></div></div><br></div> </div> </div> </div></div></body></html>
