If you are talking about a 619 dvs fisherman from Ranger, Then I will give you a what I know. I have an 04 619 with a 200 non HO evinrude on mine. I have run three different props.
21p 4 blade cyclone. 5500 to 5800 50 to 54
23p 4 blade cyclone. 5000 to 5500 51 to 56
24p 3 blade raker. 4800 to 5200 48 to 52
these boats are very load senitive. the more stuff up front will really slow you down. The 21p cyclone is great hands down in the big water. I trying to get a hold of a 22p raker and try that. I think that would get my rpms up and it will move along good.
Let me if you need more info.
