My 35 Fountain sits on a 10,000 lift and it seems to raise it easily.

Always go bigger than you need. That way you have room for enpansion. I lift a 35 fountain with a 4 motor 16000 lb. lift. Overkill for sure but i know that 42 is down the road somewhere.

I found a custom 18,000 lb Hydro Hoist for my 35ft fountain I know it is overkill but it leaves room to upgrade......BZ

found pictures....

Depends on the lift. We (I saw we meaning my lift company) had a customer put a 45' triple engine Sonic on a 12,000# lift with no problems. The lift would stall when lifing the boat full of fuel until he changed the lift motors. We also have a customer on LI that has (not sure if he still does) a 13 Whaler on a 120,000# lift. Reason being the Army Corp and EPA has cracked down and said you can only do this once. Piles can never be driven in this body of water again. So he is ready for anything.

My advice has always been by the lift that will carry your dream (realistic). Aluminum 3 post lifts will be good for 30+ years of service. So do it once and be done forever. If you think you may go to a cat someday, make sure you get a lift that is wide enough. I have converted a few lifts that were setup for V to Cats.
