Im running this Isky Cam in my NA 509, my risers mix the water at the tip right before it exits through the transom and no reverison issues. Not a stump puller but makes decent power and sounds terrific.

Yes- N/A with Bill Mitchell marine single plane intakes, 1'' super sucker and Quick fuel marine 850's
