Hi Mort,</SPAN>
You might be right. I just replaced the old shaft seal with a new of same type. It is only the stuffing that might have improved. I think it is synthetic fiber impregnated with TFPE (Teflon), so I hope it will not give too much friction, or too much water. Maybe I will start with low friction and more water dripping, and tighten it after it has run some hours. I will also lose a lot of power from the hydraulic, but most of the losses will be heat, and I will try to use that heat to heat the inside of the boat, but the friction in the shaft will be difficult to use, so it will be a loss. </SPAN>
