Bowed Up

I think kenny's right in the Pump (helm) failure. I've replace many at work.

I sent an e-mail to Teleflex (SeaStar) about my problems...

Here's my e-mail and responsewithin aday... I thought the mechanics on the board might find the response informative...

Teleflex reponse...
Thanks for the email There is no reason why you cannot use two helms of different displacements in this boat, and I agree that your thoughts are true and correct (more response out of the rudder will give you some better control in the conditions that you have explained.)

You have also mentioned that the one helm had rust and water on the inside. I highly suggest that you do the following "before" you install the new helm pump
</DIV></BLOCKQUOTE><UL><LI>completely flush out the system. You can use ATF to do this, but please only fill with SeaStar fluid once flushed out. <LI>I would suggest to go as far as to remove the hoses from the steering cylinder, and the helms. Then, using air pressure, blow out the lines free and clear of everything. </LI>[/list]
the above will prevent the new helm from being attacked by the contamination that is going on in the system

thanks and please let me know if you have any other questions

Ptetty good free service adviceI'd say...

Jim.

I remember us talking about a leak on it a couple of yrs ago along withyou having to dosconnect the upper helm lines a couple of times, my guess is that's when you contamination happened.

the reason you only have a noticable leak during the coldest part of the winter is the condensation in the system is freezing and expanding forcing some of the oil out.

Let me know if you need a hand with it, I moved but still work at the same place and the no# is the same.
