I heard from a dealer that the Raymarine auto pilots are no good on outboard boats. Under way they are slow to learn their position and make radical changes resulting in an unstable S pattern line. I am interested in the new ST8001 S1G Hydraulic Outboard Pack with their new advanced steering technology. I think the dealer was trying to sell me the simrad unit for 3k while I can get the raymarine for 1500!! Does anyone have any info on these units and how they perform??? Thanks in advance..Dal
