No. There is no 650 EFI. There is a 1000, 700 and 550 EFI, but the 650 is still carburated...........
You guys are right. I wonder why they don't put it in the name of the Prowler like they do on all the others? It is the only model without EFI in its name when you look it up. I really don't know why they would have both EFI motors. They have to be very equal in price and performance. I am curious about the 650EFI. Never heard of anyone talking about that motor.................Go to the 650H1 Prowler section and look up the "Model Features". It lists the engine as a 650H1EFI.
