<div dir="ltr"><div>Hi Guys,<br></div>Just an observation here. How difficult would it be to place the thruster into a vacumm chamber, fill up the unit with oil, run the vacumm for a little bit to draw out the air from the seal area, top off the oil as needed and close up the thruster. Then no air exists in the thruster and is ready to be placed into service.  Doug Jackson uses a similar method to pot epoxy into his electronics before it cures so there are now air bubbles.  Just a thought..<br><br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w" height="110" width="200"><br>804 College Ave<br>Santa Rosa, CA. 95404<br>(707) 536-1424<br><a href="http://www.SeaQuestor.com" target="_blank">www.SeaQuestor.com</a><br><br></div></div></div></div>
