Prop Gone? 1986 19' bayliner Capri 225E/275

[Raydar]

Well the prop fairy paid me a visit while on vacation with the wife and grandkids and now I am propless... I believe that the previous prop on the boat was a 15" x 19" aluminum but I am not sure. The spare prop is beat up and was never sized, just a flea market find "in case needed to get me back to port".

The boat is a 1986 bayliner Capri Cuddy (19' with 225E engine 275 outdrive). Mostly used for fishing and cruising with all six seats taken up. Before I purchase a new prop and accessories would like some help on the sizing. Boat always ran heavy, low RPM and slow to plane when fully loaded.

Thinking of buying this prop from IBoats while it is on sale
Solas Amita #8814-143-19 Aluminum Boat Propeller
Volvo Penta Aquamatic 275 Long Hub Sterndrive 110 - 260 HP

*Trim tabs are on my Christmas list..

Thanks for any assistance.

If the original prop was a 19" pitch and it was heavy, low RPM, and slow to plane, then the new one will be also .......

Borrow a prop or find out what pitch your spare is. Do a WOT run and see what your RPM is. That's the only way you're going to be able to make a logical choice of a new prop.

Raydar, 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 foregoing 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
19. If you are trying to attain a better cruising speed and fuel savings or trying to attain a faster speed I will want you to take your boat and run it with 1 or 2 people and give me the RPM and speed readings starting at 3,000 RPM in 500 RPM increments all the way to WOT.

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.
