Hey all, im looking for a prop for my 1991 Evinrude that had its prop shaft broken off. I found this template somewhere and thought it'd be the most helpful. BTW the boat weighs ~1490lbs with a 90hp Force on there, I dont know what it weights with my 120hp Evinrude.
1. Year, make and model of boat 1990 Bayliner Capri 1800 BR
2. Length, width and base weight of boat, look for boat decal on back of boat 17' 10" L, 7'0" W
2a.What is the maximum recommended HP for your boat 140, I THINK
3. Number of people and gallons of gas normally on boat 3 people, 15 gallons
4. What do you use the boat for wakeboarding/tube/skiing
5. Is it a Deep Vee and if so how many degrees of deadrise Dont think so
6. Year, make. manufacturer and model of motor 1991 Evinrude E120TLEIE 120hp
7. HP and gear ratio of motor IMPORTANT 120hp, 13:26
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 then do the same thing on the flywheel and turn the motor until the tape lines up with each other on the prop, 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 5000-6000 RPM
9. Anti-ventilation Plate height above keel of boat if it is an outboard in inches, use a board under the keel and stiking out to the anti ventilation plate for a referene ?
10. Is it a bass boat or does it have a pad bottom No
11. Does it have a hydrafoil, dolefin or trim tabs Yes
12. Make, model, diameter, pitch, number of blades and whether SS or aluminum prop No prop currently
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. Make sure you trim the prop up until it starts ventilating and then just trim in until it quits ventilating. If you do not have a tach you can buy a digital tachometer and hour meter here: http://cgi.ebay.com/ebaymotors/Tacho...Q5fAccessories $ 35 Bought engine without prop
RPM _________ Speed ______ GPS ______ No. of people ______ Gal. Gas ________
14. Are you at sea level or a higher elevation, give us the elevation in feet 300ft
15. Has your motor been tuned up lately and have you checked that the carburetor butterfly is opening all the way by just pushing the throttle at the helm and not at the carburetor, checked compression, and looked at the plugs and checked spark as well as timing and advance, all of the foregoing could be the reason your prop is not attaining full RPM NO
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 The boat needs to be a recreation boat right now, for skiing, wakeboarding, and pulling a tube. Later it needs a prop for fishing, or cruising the lake/being fuel efficient.
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.
