What kind of PRM's do you guys think is safe for this engine to turn. This motor is still completely stock. It is going on a 16ft Hydrostream.

I was told that some guys are turning them 7000 and not having any problems but that is on carbureted engines. The only reason I'm asking is because of the EFI system and the mechanical oil pump.
