Hey Spare. 2001 optimax 150 injected. Should I look out for anything? Would you go with something like this over a similar Yamaha?

as far as direct injected engines go, they are as good as they get. That being said, they are direct injected engines, so that's only so good. There a reason no one is building DI engines any more. what year model? how many hours? has it been setting for extended periods? Run regularly and maintained properly, they are known to go 1000 hours plus(saw one that had 5000 hours), bad fuel, overheat, etc will kill it instantly(as it will most engines). Before 4 strokes' came of age, I would have picked a 2.5 opti any time. After seeing them in the field for a long time, discovering just how much they can cost you if they break, I'm a bit cautious about them. The internals of the powerhead cost the same to replace as a carb motor, if you have a major failure. Its figuring out what caused failure, and repairing it that gets $$$. 12 injectors, air compressor, 2 electric fuel pumps, $25 a piece spark plugs, expensive two stroke oil, etc...

Are you saying stay away from this one?

if it runs good and checks out, go for it. the issue with all the DFI engines is there is enough crap on the outside of the motor that can go bad that will be cost preventative to justify repairs, with eth engine internals being fine. Let alone if you have internal issues.
