I don't know the first thing about Yamaha motors. I am used to the Mercury line up and what each model is.
Can someone tell me the difference between the VMAX and the VMAX HPDI?
Also, how reliable is each? Advantages/disadvantages? I am looking at buying a used Skeeter and one of the ones I am considering has a VMAX and the other one has a VMAX HPDI.
