I have done this, and all you would need is a flat plate at the back of the sub to bolt the assembly onto. The assembly has the seal in it as well as two bearings to carry the shaft. I picked one up at a junk yard and replaced the seal and bearings.</div><div>Hank</div><div id="yahoo_quoted_6215822487" class="yahoo_quoted">

It's just a spring loaded mechanical "pump seal". The PS-309 is still available from many suppliers however it is 7/8 diameter so you'd need something similar but larger for your 1" propeller shaft. There are other types of mechanical seals that will work as well.</div><div class="yiv0540768531qtdSeparateBR" dir="ltr" id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5729"><br clear="none"></div><div class="yiv0540768531qtdSeparateBR" dir="ltr" id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5729">Jon<br clear="none"><br clear="none"></div><div class="yiv0540768531yahoo_quoted" id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5687" style="display:block;"> <div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5686" style="font-family:times new roman, new york, times, serif;font-size:16px;"> <div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5685" style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div dir="ltr" id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5684"> <font id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5728" size="2" face="Arial"> </font><div class="yiv0540768531yqt3903817124" id="yiv0540768531yqtfd43489"><hr id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5786" size="1"> <b><span style="font-weight:bold;">From:</span></b> james hughes via Personal_Submersibles <personal_submersibles@psubs.org><br clear="none"> <b><span style="font-weight:bold;">To:</span></b> Jon Wallace via Personal_Submersibles <personal_submersibles@psubs.org> <br clear="none"> <b><span style="font-weight:bold;">Sent:</span></b> Monday, August 27, 2018 10:15 PM<br clear="none"> <b><span style="font-weight:bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Lurker finally surfacing!<br clear="none"> </div></div><div class="yiv0540768531yqt3903817124" id="yiv0540768531yqtfd51320"> <div class="yiv0540768531y_msg_container" id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5688"><br clear="none"><div id="yiv0540768531"><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5691"><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5690" style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5727">Hi Jon,</div><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5689">Thank you for your advice! I've not looked at the motor pod drawings of the K250 in more than a decade because when I first started out I bought two 40# thrust motors from the Kent Corporation and figured I would just use those. Looking at the drawings now I can't seem to see the details I think I would need build (or tell my nephew how to build) such a part. It's not clear to me what kind of seal to use (many other parts Captain K. was spacific about, like o-rings and valves) or the size.</div><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5692">Thank you for your recomendation for All Seals Inc. I bookmarked their website some weeks ago and intend on paying them a visit next week (I've got to wait until I get paid on Saturday). Fortunately, I live only a few miles from their Lake Forest location. I think I've seen a seal that will work for me in their catalog and a calculation that shows how much room I need (after compressing the spring) to firmly hold the seal in place inside the through hull connection. Now I need some education in bearings. There is another site that I may contact about those if no one on this list has a recommendation for me. Thanks again!</div><div id="yiv0540768531yui_3_16_0_ym19_1_1535454153043_5726">God bless, Jim</div><div class="yiv0540768531yahoo_quoted" id="yiv0540768531yahoo_quoted_5642602902" style="display:block;">
