What Prop to use on my 2oo Johnson

[BigFishin82]

Ok you guys I have a question for you.  What size prop should I use on my 200 hp Johnson that is mounted on my 250 CCP center console?

Start with a 14x17 stainless 3 or 4 blade.  4 blades will give a better hole shot, 3 will give better top speed.  See what you get for RPM at top speed and adjust as needed.

Thanks for your wisdom

I have a 250CCP with a 200HP Suzi (2 stroke) and I'm running a 14 x 18.5 stainless 3-prop.  Gets up on plane pretty quick fully loaded, but can't get much more than 30 knots @ 5000 rpm with a couple of people on the boat and around 26 knots @ 5000 rpm fully loaded (8 - 9 people plus gear).

will a 15x17 prop do the job on my 250ccp with the 200 hp johnson?

15x17 should work pretty well, but you never know until you try it!  

See ya on the water!

[COLOR="Blue"]Iboats Boat and Motor Info[/COLOR]
1. Year, make and model of boat
2. Length, width and base weight of boat, look for boat decal on back of boat
2a.What is the recommended HP for your boat
3. Number of people and gallons of gas normally on boat
4. What do you use the boat for
5. Is it a Deep Vee and if so how many degrees of deadrise
6. Year, make and model of motor
7. [COLOR="Blue"]HP and gear ratio of motor IMPORTANT[/COLOR]
 If you don’t know the ratio, you need to pull the plugs out and put a piece of tape across the prop and the lower unit and then cut it between the prop and the housing and turn the motor until the tape lines up with each other, it is easier if two people do this, so one can watch the prop while the other counts the revolutions of the motor
8. Manufacturer’s recommended Wide Open Throttle (WOT) range
9. Anti-ventilation Plate height above keel of boat if it is an outboard in inches
10. Is it a bass boat or does it have a pad bottom
11. Does it have a hydrafoil, dolefin or trim tabs
12. Make, model, diameter, pitch and whether SS or aluminum prop
13. WOT RPM and speed from your current prop and how much gas and how many people were in the boat for the test data and is the speed by GPS. If you do not have a tach you can buy a Tiny Tach for $ 50
14. Are you at sea level or a higher elevation, give us the elevation in feet
15. Has your motor been tuned up lately and have you checked that the carburetor butterfly is opening all the way, checked compression, and looked at the plugs and checked spark, all of the forgoing could be the reason your prop is not attaining full RPM
16. How long has this prop been on the boat and why, at this time, do you think it is the wrong prop
17. Does the prop show any damage that you can see
18. What problems are you trying to cure or what are you looking for the boat to do that it is not doing the way you think it should or to your expectations

[SIZE="1"]REMEMBER, The numbers I give you will be NO better than the information you give me[/SIZE]

[COLOR="Blue"]The only thing I ask of you is to come back and give me a report of WOT RPM and speed for my database.[/COLOR]
