Re: Prop help
H and Dhadley
Thank you both for responding. This is my first boat and I apologize for my ignorance as I am still learning. Dhadley I will answer you first (since its much shorter) and H I have answered as much of your questionarrie as possible and will post below.
I double checked the prop and I believe it is a shooter (only thing it says that refers to a make or model) it does say 13 1/4 which I verified with a tape measure. It also says 25 PP which I assume is the pitch. The motor is a V6 150 HP Johnson, whether it was rehubbed or not I cannot say but if there is a way to check Ill be happy to do so.
H the responses to your form are below -
1. Year, make and model of boat
- 1990 Tracker Nitro 185TF
2. Length, width and base weight of boat, look for boat decal on back of boat:
- Length 18'10" Beam 7' 3"
2a.What is the recommended HP for your boat
- 150hp to 185 hp
3. Number of people and gallons of gas normally on boat
- 2 adults (sometimes additional 2 teen girls) 20-30 gallons of fuel
4. What do you use the boat for
- Primarily fishing but occassionally to pull a tube.
5. Is it a Deep Vee and if so how many degrees of deadrise
- Bassboat
6. Year, make and model of motor
- 1990 Johnson 150HP model TJ150SLESB
7. HP and gear ratio of motor IMPORTANT
- 150 HP 1.85:1 (believed to be)
8. Manufacturer?s recommended Wide Open Throttle (WOT) range:
- 4500 - 5500
9. Anti-ventilation Plate height above keel of boat if it is an outboard in inches
- excuse my ignorance but Im not sure what that is.
10. Is it a bass boat or does it have a pad bottom
- bass boat
11. Does it have a hydrafoil, dolefin or trim tabs
- Hydrofoil
12. Make, model, diameter, pitch and whether SS or aluminum prop
- On the prop itself it says - 13 1/4, 25PP, Shooter, and it is stainless steel
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
- Best RPMs I can get pre-planing is about 4000, if/once I get on plane it will hit around 5200. I do not yet know the speed but will test that tonight.
14. Are you at sea level or a higher elevation, give us the elevation in feet.
Roughly at sea level.
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
- I have replaced the fuel filter, fuel pump, fuel lines, spark plugs, and replaced the gas in the tank. I will be checking compression and spark this weekend and I plan to order the kits to rebuild the carbs soon (20 year old motor figure it wouldnt hurt). I have only owned the boat for 2 weeks so I cannot answer what was done prior to my obtaining it.
16. How long has this prop been on the boat and why, at this time, do you think it is the wrong prop
- I do not know how long the prop has been on the motor. A post I placed on another board about cleaning it indicated it may be the wrong prop for this boat/application.
17. Does the prop show any damage that you can see
- Other than a few scratchs and very minor nicks nothing major. I can post a picture if that helps.
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
- I am a fairly large guy but even with just me in the boat it can struggle to get on plane. I do not care so much about top end speed, I do care about getting it on plane as easy/quickly as possible. Partly for tubing but mostly because I dont like having a difficult time seeing whats in front of me while trying to get on plane.
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.
- I will be happy to do this.
