1996 Mercury 250 EFI with 25" shaft for sale
Up for sale is my 1996 Mercury EFI 250 motor with a 25" shaft length in excellent running condition. Recently replaced in the past few weeks, alternator, belt and plugs, Last fall replaced coils and plug wires, had Brucato flow and balance injectors, new low and high pressure fuel pumps. I also had the heads cut to 300 ProMax Spec and for new style o-rings and I also have a 300 ProMax fuel and ignition ECUs that's included. But the motor runs alot better with the 250 ECUs the motor came with, not sure about there programming. I'm unsure of the total hours, but when I had the heads off last summer I saw visible cross hatch up to the tops of the cylinders and compression is between 112 and 115 with motor cold. Haven't done a leakdown yet, but can be done if needed. It's still on my boat if someone wants to water test. It pushed my heavy a** 1978 Mako 21 with a T Top to 46 mph yesterday at 5600 RPMs and a 17 pitch rev 4 prop. The lower unit was replaced last year with a like new 2005 TorqueMaster from a 2005 Optimax 250. I also noticed when I did the injectors that it has carbon fiber reeds installed. Motor is setup for premix. Asking $3800 or best offer. Shipping is available, but not included with my asking price.
