Mercury Racing 225 Promax with essentially a new powerhead. Engine was built with a new factory block, piston kits (WSM with 1.5mm rings), steel cage rod bearings, all new electrical components (regulators, stator, trigger & switch boxes). A32 ECU that was just serviced at Simon motorsports w/ a year warranty. New TDR reeds, injectors cleaned & flowed. All new cooling components - poppet valve, thermostats & waterpump. The engine has about 15 hours on it for break-in, testing and tuning. Factory Promax midsection, Alien Style Factory light weight cowls. Ratcheting 1.87 lower unit with welded Bobs cone lower water pickup and torque tab on skeg. Probably forgetting a bunch. The motor looks new and run great. A Promax I built that is identical to this one peaked at 242 HP on the dyno. The only reason I’m selling it as I just bought my old 280 back and something has to go. Motor can be demonstrated and installation is available. Trades-ins of similar Mercury outboards will be considered. $7800 Firm, Call or Text me (Mark) at 757-84six-897one.
