[CA] [CA11] Auto Pilot pump conundrum

RE: [CA11] Auto Pilot pump conundrum
Welcome back to the Raymarine Forum Tony,

As indicated within the FAQ found here, the total capacity of hydraulic fluid that will need be pumped through steering rams which have been plumbed in series will be equal to the capacity of one of the steering rams. However, the total capacity of hydraulic fluid that will need be pumped through steering rams which have been plumbed in parallel will be equal to sum of the capacities of each steering ram. Should your steering rams have been plumbed in parallel, then the total cubic capacity for two 8.3 cu. in. rams would be 16.6 cu. in., requiring a Type II Hydraulic Pump and an ACU400.

If the latter is so (recommend verifying the hydraulic plumbing), then is accordingly recommended that the ACU-200 be sent to Raymarine’s Product Repair Center to be replaced with an ACU-400 (they will charge the differenced) and that the Type 1 hydraulic pump be replaced with a Type II hydraulic pump.
