<div dir="ltr">Hank,<div><br></div><div>Am I correct in assuming that you only drilled and tapped a hole in the prop end to add oil but there is no bladder for the oil to expand when hot and why did you choose that end to drill instead of the other end or body of the motor?</div><div>You also mentioned that you get a little fresh water in your motor when you change out the oil every year. Do you think that this is because there is no place for the expanded oil to go when it gets hot so when it does, it pushes out past the prop shaft 0 ring and also allows a little lake water to come the other way when the oil cools down? We have no lakes on the big island so my diving will always be in salt water which will not be good on the insides.</div><div><br></div><div>Rick </div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Dec 5, 2016 at 7:31 AM, hank pronk via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:12px"><div><span>James,</span></div><div><span>No bladder, nothing, fill er up and go diving.
