Some of you guys got me thinking about the fill level on the helm and what type of cap should be used on a baystar helm, so I called the teleflex tech support and asked them about it. They said on the baystar helm with balanced ram you can use either a vented or nonvented cap. It makes no difference as to how the system will work and both caps come with the kit. They don't recommend using the vented cap on boats with the helm exposed to the weather and washing as they see contamination to the fluid in these situations. Not an issue with a C-Dory so you can use either or it makes no difference. Ours has the vented cap on it.
The fill level is recommended to be from the bottom of the threads of the fill hole to 1/4" below the fill hole. However he said that it will not hurt anything to have it filled to the top. The only problem it can cause is that on a hot day it can puch out a little fluid if you have the vented cap or when you open it up. It will cause no harm to the system or the seals. If the level gets too low it can introduce air in to the lines and steering ram. I have had ours filled to the top and have had no problems with fluid seeping out the vented cap during the year it has been installed and 140 hours of use. It does not get that terribly hot where we live.
