Re: 1999 150 Optimax
Problems were mostly in the upper hp range for that motor. It should be fine if some of the updates have been done, I would take it to a dealer and pay him to run a computer scan on the motor. If the price is right go for it, you will never know if you are lucky or not unless you do, buying a used motor is always a crap shoot. By the way I have a 2000 Opti 135 and it has had some petty problems, how ever the all newer dfi motors had some problems.
