I still say go with the Merc 420 cam. It's a crane cam. Mine pulled hard out of the hole all the way to top. I had propped for 5200 and pulled to it.

As far as cams go, the 420 Merc cam typically doesn't get rave reviews. Glad it meets your requirements goob.

Waterfoul's cam was a very good selection for his engine/boat package. I understand it ran very well at LOTO last spring. I'll see if I can get him to post in here about the performance.
