How do I identify the model number of the piston that connects the rudders of the boat.

How do I identify the model number of the piston that connects the rudders of the boat.

Submitted by: ronald
Answer

Normally there is a tag or the numbers stamped into the hydraulic cylinder. If you can’t find any identification, send us pictures and the dimensions of the rod and the cylinder barrel.


Question
Capilano fluid

I just bought a 1275 capilano helm pump to replace a seastar pump. Mainly to reduce the number of turns. It called for seastar fluid before but I see now that capilano calls for dextron II is that correct? I wouldn’t want to damage the new pump.

Submitted by: animalduck
Answer

Both will work, Capilano calls for ATF as the helm can be dialed down to accomodate for the heavier effort that ATF will lead to… SeaStar helms cannot.
