Iboats Boat and Motor Info

2004 Crestliner 1700 Super Hawk
2. Length, width and base weight of boat, look for boat decal on back of boat
17'7", 7'6", 1135lbs base
2a.What is the recommended HP for your boat

4. What do you use the boat for

5. Is it a Deep Vee and if so how many degrees of deadrise
Deep Vee
6. Year, make and model of motor
2004 Yamaha 90TLRC
7. HP and gear ratio of motor IMPORTANT
90 HP, 2.0 Ratio
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
4500-5500
9. Anti-ventilation Plate height above keel of boat if it is an outboard in inches
about even (maybe an inch higher than the keel - dark out...may need to re-do during the day)
10. Is it a bass boat or does it have a pad bottom
No
11. Does it have a hydrafoil, dolefin or trim tabs
No
12. Make, model, diameter, pitch and whether SS or aluminum prop
Aluminum Prop, Make: Michigan Match Aluminum (model 101033) 13.25" with 17 pitch
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
WOT: 4800, 12 gallons, 34 mph (not GPS), 2 adults/2children
14. Are you at sea level or a higher elevation, give us the elevation in feet
604 feet above 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
16. How long has this prop been on the boat and why, at this time, do you think it is the wrong prop
Just bought the boat and it had this prop
17. Does the prop show any damage that you can see
No...
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 want to switch to a stainless steel prop and make sure the boat is running at its best, preferably stay with 3 blade...I would appreciate recommendations (fairly new to owning a boat). Looks like I do not have the right prop for the boat, but plan to save the aluminum for a spare.
