Re: Hard Steering
SeaStar hydraulic steering is in the $700 range plus labor to install it. Someone that's handy can install the steering system and bleed the hydraulic lines.
I have it on my Bennington with a 150 hp outboard. But over 30 mph, my boat is even a little hard to steer. If I wanted to spend another $2K, I could put electric power steering assist on the boat. Any 200 hp or larger pontoon would need the power steering assist, however.
You might want to check into the condition of your steering cables. You might be just a couple of squirts or grease away from easier steering.
