when you change a impelle do you half to take off the powerhead and if so there is a cover thats on the back of the down shaft that looks like i have to take off to get to one of the screws what is the cover for and should i buy gaskets for that and the powerhead they both have one. im also having trouble taking off the flywheel. any help would be very much apperciated. if this site is to small to list help email me at raowens@yahoo.com thanks
Yes, I seem to recall that the powerhead does need to come off, to undo the shift linkage. The same holds true for the 5 1/2's. Typically, most motors will have a small obround plate in the lower part of the motor leg, just above the water pump assembly, but that is on 10hps and larger. The smaller motors got the 2 piece shift rods a little later than yours.
As far as the flywheel goes, you'll need a good puller. Be careful about the top stud that you don't damage the threads, because that will ruin your afternoon.
The triangular cover you are speaking of is a muffler. Take it off to access the screw above it. You can usually reuse that gasket. Even if it leaks real badly, the worst that can happen is a noisy, messy exhaust.
Always use a suitable puller on the flywheel, one that goes in the 3 bolt holes in the flywheel. And always use a torque wrench to reinstall it. Torque is 40-45 ft/lbs on that one.
If you can't get the proper puller and torque wrench, keep your hands off it.
thanks for the reply. i got the impeller changed it was easier then i thought it was going to be. now i just need a puller and change the coils and im in business. I HOPE
well i got the right puller but i still cant get it off the flywheel keeps spinning when i try to tighten the center bolt on the puller. and now i have another problem. i can't get the lower end fill and drain oil bolt out. it is really stuck. i am going to try to heat it up with a torch and mabe that will loosen it. if there is a NO NO about this let me know. i am not going to try this until mon or tue. thanks for the help
yea, make sure that you have a screw driver that fits the slots on those drain plugs, as much as possible, because they will booger up on you. They usually have a plastic washer that compresses , so they shouldn't be too tight.

You need a strap wrench to hold the flywheel. You can make your own with a piece of 2 x 2 lumber and a nylon web strap. Shown in tightening mode. Flip it over for loosening mode.
that is the most coolist thing i have ever saw and looks cheap to make. im going to make it tomorrow. this beats trying to hold it and my hand sliping off and hitting myself in the face. im glad no one was around it most likely looked funny. i dont know how i hit myself in the face but i did. i am going to make it and see how it works thanks. one other question. how does a person gain rank. anyways thanks for the info.
coil and impeller change on '54 7.5 Evinrude
Linear Mode
