I have for sale a 2001 mercury 125hp outboard engine.this was on a 26 foot pontoon that got wrecked on the highway during transport.i bought this to go on my pontoon but I think it is too big for a 20 foot pontoon.i looked up and a new 125hp mercury will cost $11k right now so I think this is a very fair price.i do not have any controls .engine only.i am in no hurry to sell it because if I don't sell I will find a bigger pontoon and put it on it.if interested call .comes with a brand new set of mercury controls ordered direct from mercury.
