I'm in the process of repowering my 280 PRO as a winter project. If you know anyone doing a part out of a 2.5 Merc 175 EFI, let me know. Looking for good used crank and one rod. As always there will be some mods along the way. First will be to open up the venting on those heavy as hell cowls and strip out the foam and glued in rear panels. then open up the aft top vent section as well as adding a fwd clean air intake.
