Yep, I've got Pfaff 900's. I'm very happy with them so far. They have consistently run well over a long period of time. Both Paul and Gordon have been extremely helpful and responsive with all follow up service and attention.

I give them high marks :)

I have a PFAFF 468 that was built in 1983. I rebuilt this past season and upon teardown the crank looked like it had 10 hrs on it. Sent the rods to have new pistons mounted and after 18yrs he still had the weights of the rotating assem. He sent them back all balanced, sized, bearings and rings, all at a very reasonal price. After building and 25hrs break-in I ran a fun run, well under propped and ran the boat @ over 6000 rpm for about 45min, and it just SANG. In my opinion he is one of the best in design and service.

I drove a 34 Eliminator eagle with Pfaff EFI 700's or 750's, not sure of the exact horsepower. It ran over 100 and accelerated at at least a gee, felt like a snowmobile on grass from 50 to 80mph. What a blast. Idled good, ran great, but for some reason stock B1's didn't hold up ;)
