Not sure but think i might have a prop issue. I have a 200hp johnson on a 20 foot f/s. I have had some carb and throttle problems at low speeds but never at WOT. I run a 14.5 by 24 raker prop. I have always run about 68 mph at 5500 rpm's. End of last season I was exactly that. This year i had a tune up and and carbs cleaned and a starting problem fixed. I also had my prop redone, had some nicks and have hit a few things in the past. First time out this year i could only get 60mph at 4900 rpm's. I went back to the shop and went over the engine and everything seemed fine, compression, spark, and carbs. Then i went back to prop shop and he said NO WAY it was the prop. But he did say the prop needed to have the nicks fixed, and rebent and had to be cupped some. {i believe cup is the end part of the blade on the prop}. Could he have cupped and or bent the prop too much to cause me to lose 600 rpm's. It would be crazy to just go out and buy a new prop just to check when i paid alot for this one and alot to have it "fixed". Not sure what to do to get my rpm's back. {sorry about the long type} thanks.
