I do no know what model. A friend of mine is buying one and I could not give him any info. I have rebuilt many omc's and one 130 yamaha but I am not familiar with vmax 150
if its just a v150 its carbed,vz150 would be HPDI and vx150 would be ox66 the v tells its a vmax model the z is hpdi the x is ox66 efi.<br /> good luck and keep posting
