T&T: Hydraulic steering problem

[Larry N. Brown]

Don,

I have the Hynautics 3 line system on Cigano and I had the identical 
failure. The boat had the original system installed in 1981. While the boat 
was in the yard, I pulled the upper and lower helm pumps and the tiller ram 
and sent it to a place to have them professionally rebuilt. Installed them, 
bled them and everything seemed OK. Until we started going out for engine 
trials. The upper helm did just what you describe.

Sent it back to the rebuild place and the news was bad. Seems Hynautics 
constructed the pump frame out of aluminum and the pistons of steel. 21 
years of wear introduces enough slop in the cylinders that even replacing 
the seals won't help. You can get a new pump for just a little more than a 
new case and the costs to rebuild it. This was 3 or 4 years ago but I think 
it was in the neighborhood or $650.

Regards,

Larry and Teri
