I believe you can add more lift capacity to a 9000. Check with hydro hoist. They have add on chambers I believe.

Well I just watched your video and in my opinion the Sunstream design sucks!

I can walk all around my boat with the lift up or down and I can get off my boat with the lift down! The Hydrohoist may be slow but it's looks a lot more stable. All I just saw was a gadget not a tool!

I have a 10,000 lb. lift under my 2001 Classic. My hydrohoist seems to work well with mine. Going on year 5. It takes a little time to raise, but it seems to go up strong. I have the company over every few years just to check things out.

This is correct.

I bought a new 10,000# when I sold my old 10,000# lift (I wanted the newer technology in the new lift). However, when I bought my Cig, which is about 11,000# full of fuel/gear. Hydrohoist put an additional tank in between the two existing tanks. I now have about 13,000# lift capacity.

In this situation, where you have two blower motors filling three tanks, when the lift rises to full up position, you have to isolate each tank fill hose by way of valves in order to keep air from transfering from tank to tank. Works great.

This was much easier than selling and buying a new lift.
