I found a 1975 Evinrude 25 horse for 500.00 Im not familiar with these motors. Says its fully functional and everything works. How would i know what this thing is actually worth? Thanks
Run it. Throw it in a barrel or the back of a boat. Pop the cowl and see how clean it is... See if it has been started before you got there, warm? How difficult is it to start cold? Pull the rope, feel like it has good compression? Does it go into Forward and reverse? Does it pee? Good idle? Short shart or Long, which do you need?
If you can't run it I wouldn't pay anywhere near that much. If it does all these things then it might just be well worth it.. wouldn't hurt to nego. If it doesn't do these things then it's really up in the air how much it might cost to fix, you could easily spend $500 repairing it if not doing your own labor.
