Re: 7.5 Evinrude and original fuel tank
Post some pics if you can, we love to see these old girls.
Sitting as it has, you will likely need a full tuneup, or let me reprase that, you will need a full tuneup.
First thing that I would do is check compression, to ensure all is well with the powerhead before spending any money. I believe all of my 7.5's are in the 80 to 95 psi range, and should be equal between cylinders.
After that is out of the way, time to pull the flywheel and inspect the ignition. Have the coils been changed? You will know right away, if they are cracked and rotted, they are original and will cause immediate trouble, change them. Would also be the time to refresh the points/condensors. These parts are available just about anywhere. While the coils are out, change the plug wire with new copper core wire, available at your local NAPA.
Once the flywheel is retorqued, time to clean/rebuild the carb. This would include new fuel lines, as the old ones will be cracked/rotted and not ethanol resistant. Let us know if you need help with this.
Now it is time to drop the lower unit, and change the impeller. You will need to pull the powerhead to do this though, not a big deal, we can walk you through it.
Once bolted back up, change the gearcase oil and she will be good to go for another number of years.
If you need help with manuals, PM me. Post your model number so we can give more specific instructions.
Good luck.
