Yes.Between your prop shaft and the prop is a rubber bush inside the prop.Its there to stop major damage to the entire driveline if you hit something.Its needing replacement.Most prop shops are cheaper then a dealer or you can go to an outboard wrecker and get a replacement.Its the prop bush and it will fix your problem.Hope this helps
It sounds like the Rubber hub in the prop is slipping. There are 2 systems used to prevent gear damage, shear pins or Rubber hubs.
The outboards and I/Os' use a Rubber insert in the prop. Unless yours is an OMC all the rest use the Rubber hub that is pressed into the prop. It has to be sent to a Prop shop for replacement. Some OMC props are 2 piece inside with the prop sliding over a replaceable do-it-yourself hub insert. Its kind of slick because OMC did lower the cost of every replacement prop and keep you on the water with a fix you can do.
The RPM for your problem is the Red flag. The engine did not refuse to rev up. This means the gas and spark are working and thats all you could want.
With the RPM I suspect you are overreving the engine at 8,000. The hub will get looser and eventually you will have no propulsion.
If you are anxious to get back on the water you could buy a spare prop. Contact the dealer for any change you want to make in pitch or size.
there is a plastic nut that screws onto the prop shaft and needs to be unscrewed. there is also a metal pin that goes through the shaft that needs to be in place and in the right position when you replace the prop. make sure you clear out any fishing line etc that may have collected behind it when you change props.sually recommend you put a little clear silicone grease on the parts as you assemble them as well.ake sure you disconnect the power leads from the battery while your doing this to avoid injury.
It sounds like the prop bushing is bad. There are 2 systems for preventing gear damage,shear pins and rubber prop bushings.
The rubber bushing can be molded to the prop or there is a type that has a sleeve the prop fits over. If the prop has no sleeve you need to take the prop off and have it relined. It will fail soon, its just a matter of time. If you have the removeable sleeve, you replace the sleeve and just slide the prop over it and you are done.
The diminished thrust is due to the rubber slipping from its bond and it will get looser and looser.
You can get aftermarket seals and such as long as they match the old ones. You can also use Lubriplate 105 in the gearcase instead of the High Performance gear oil. The 105 is alot heavier and will not hurt it. It will actually get you more life out of a tired gearcase. The main thing that you want to remember is that you have to put the engine in fwd gear and then disconnect the shift linkage. That is so that when you are reinstalling the gearcase you can turn the prop by hand to line up the splines in the powerhead. after you disconnect the shift linkage you should be able to just slide it right out. Make sure that you replace the seal under the waterpump base also.
Odds are you have sheared the pin (slides through the prop shaft) holding the prop, or you have damaged the slot on the prop that the pin sits in.
Prop is secured to the shaft with a metal nut, or flat plastic wing nut. Remove the nut to remove the prop. You may have to pry, slightly, the prop from the motor housing. Removed, you will see a whole in the shaft where a pin should be located. If the pin broke, it probably hit the floor when the prop was loosened. If the pin is intact, examine the rear side of the prop and look for damage to the plastic slot where the pin would sit making contact.
If you've snapped the pin, you can make a replacement with a nail using a hacksaw. Replacement pins can also be ordered from Minn Kota. If the back side of the prop is damaged (recess for the pin to sit), the prop is toast. Replacement props are often carried by Walmart, and include a new pin.
If neither part is broken, perhaps the prop was just not seated on the pin correctly allowing the prop to freewheel.
there will be either a bolt at each end or a spring slide, if it is the slide just push it along with a screwdriver and the support will just pull off. make sure to prop the tailgate or get someone to hold it up for you or it will fall on your head and that does hurt...........a lot. (I know)
You need a steering wheel puller tool.Another way is to put the nut back on the shaft(so as not to damage the threads),prop your knees against the steering wheel using blocks at your feet,apply as much pressure as you can on the wheel pushing it towards you & then tap the center shaft with a BRASS hammer.Careful not to hurt the threads.Good luck, ChevRev
