Yamaha 225 HP HPDI Vmax 2 Stroke Outboard Driver Injector. These parts is good for several Yamaha HPDI 2 Stroke Models. The outboard engine was a 2004 HPDI Vmax 225 HP. Note : Have more parts from this engine listed in other auctions, just in case are interested. This unit was removed from an engine with compression issues, the engine was sitting for a while, I don’t know how to test this unit , let’s say unknown condition no idea if there are problems or not. Decent cosmetic condition Just took a lot of pictures, take a look please, some extra parts are included too, Thanks. Some of the items that I list as ” for parts or non working ” might be in good condition but I’m listing them in this category for extra precaution , and to be fair, just in case the item is not good. Sometimes I just was unable to test it or some parts or screws might be missed. Just check my prices and feedback. Good deals, pretty hard to find.
