1997 Celebrity 180 What prop pitch

[Flipper1983]

Good afternoon

I have a 1997 Celbrity 180.

Engine 4.3 Liter Mercruiser 4 Barral 205 horsepower

Alpha one outdrive ( unsure of gear ratio )

WOT 4600 RPM

Boat weight dry 2300 lbs

Purpose cruising with the family pulling tubes, skies, wakeboard

Currently the boat has an aluminum 3 blade 19p prop

Great top end but I would like to see it get out the hole and get up on plane a little better. I had four adults and three small children in the boat ( all fit adults all kids under 3 ) and it just didnt want to come out and get on plane. once it did we were good to go flying across the lake. Also I almost wasnt able to get my father in law out the water on the skies. He is about 220 I just think the boat should do better than that maybe I am wrong, and its not like I am pushing max capacity we are always light.

What is the correct prop pitch for my boat and also would I be better off running a 4 blade instead of a three? I have read that a 4 blade will hold better low speeds and get out the hole and on plane better.

Any advise would be great and if I have forgotton any specs that you need to calculate please ask and I will get the info.

Thanks
Richard

Richard, welcome to Iboats prop forum and we will try to help you as much as we can but without more information no one can help you, and I will tell you I need more information than anyone else. But if you would like my help fill this form out and I will help you as much as I can, if you would prefer to not go to this much trouble there are other people who will help you.

Iboats Boat and Motor Info
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. HP and gear ratio of motor IMPORTANT
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

REMEMBER, The numbers I give you will be NO better than the information you give me

The only thing I ask of you is to come back and give me a report of WOT RPM and speed for my database.
