Hynautic Engine Controls

[MicroKap]

I have a 1980 60' Hatteras Sportfish located in New Jersey. I have the original Hynautic R-04 Reservoirs (one on each side; original with rectangular sight glass on exterior) for a three station setup. The port throttle would not get the engine above 1,400 rpms and the rpms would continue to drift downward. I checked the system for leaks this weekend and found there to be a substantial leak from the back side of the top casting where it meets the cylinder. I removed the unit from the boat and was able to disassemble most of the pieces to see if I just needed a new O-Ring set, but couldn't get the top of the unit off. I was able to remove the air/fill plug, the dill plug and the pressure gauge from the top. On the bottom, I removed the center bolt. When I removed the dill plug (center) from the top, the "bolt" had a lot of rusty flakes falling off. I know there was no fluid leak, just air leak. The starboard system is about the same, but doesn't loose air pressure as fast.

Please let me know what parts I would need for replacement. I would need the parts by Thursday afternoon and Teleflex in FL was closed today because of TS Faye.

Thank you very much for your help.

Larry,
Come on back down to Jacksonville and when you buy my dinner (again) at River City Brewery, I will give you the answer....

You might want to wait a week till this "little storm" Fay goes away

Charlie,
I'm looking forward to coming back down again and spending more time with you in Jax

Teleflex is supposed to be opened again tomorrow. What's the answer to my problem?
