I ran my friends Champion 190 FS last week with a new 200SS and what an engine! Super impressed with how smooth, quiet and powerful that engine is for a 4cyl. He's running a Suzuki 15x21 prop and hitting 57mph @ 6k. Running those numbers put him at 4% slip and that's pretty good. The engine and boat ran better the more I trimmed. At max trim the boat lifted great and ran amazing. We are going to try a 21 Scorpion next as it hit the 6k pretty easily. I'd be curious to see what a 23 Tempest would do but so far its a very respectable numbers for a Fish N Ski and 3mph off from what the other brands are getting on the same boat.
