I am helping my father with his pontoon boat. It is a 06 Avalon 27' with a 5.7 mercruiser and alpha 1 gen 2. The problem is that the first time that we took it out it was so hard to steer that it took both hands. The power steering system is electronic and does not use a engine pump. We have bleed the system and it is better but still hard, and you can hear the pump running even after you stop turning it (not sure if it made the noise last year) I have dealt with elctronic steering in cars but they are full electric with no hydraulic fluid, this has an electric pump and hydraulic fluid. any help would be great.
