Re: 1973 Evinrude impeller change need help..

Pizazz,
I looked and your lower unit is definitely from the late 80s at the oldest. You can see in this part diagram how similar this '87 model lower unit is. Part #73 is the keeper that I'm talking about you'll have to take off. It will look one-piece but is actually split and you'll have to gently pry it apart with a thin flat-head screwdriver. Don't let it fly off because it's tiny and will bounce all over the place and you may lose it.
Good luck with your "newer than you thought" motor! http://www.crowleymarine.com/brp_parts/diagrams/28212.cfm

pizazz, I am sure by now you probably realize that is a stolen motor. The thief took the number plates off an old junker and switched them out. Have to admit, he was no amature. He was smart enough to change the welsh plug on the powerhead too. Cash deal, no bill of sale?

I didn't want to say it, but I was thinking the same thing, F-R. I'm astonished someone would be able to fit a welch plug from a '73 in a late 80's model, though! Or I guess they could just have the number stamped into the right plug?
Either way, somethin's up with that motor..:redface:

Hey guys it does say 391088 stamped on the top of the motor itself and D J P but I don't know if that means anything. If the numbers are changed wow thats a good job, the original owner passed away at a young age of like 45 or something so I cant ask him.

I hope Pizazz that you don't think I'm pointing fingers at you with that quote above! I wouldn't have looked at the model number either, and if I did, wouldn't have known if it wasn't right. Just because you got a good deal, if that were the case, doesn't mean one should immediately suspect it is stolen. Heck, there could be some other explanation (although doubtful) and either way, it's none of my business.
Good luck fixing it.

Re: 1973 Evinrude impeller change need help..

Do I need to take off the exhaust housing to change the impeller? And its an electric/manual start, there is no oval shaped plate on the exhaust housing. The model # 25302A which always comes up 1973

You might have a 1978 motor as your model number is probably 25802 - what you thought was a "3" is most likely an "8". The 1973 motor was a completely different engine and gearcase design than what you have pictured.

Like was previously mentioned, remove the water inlet screens to access the shift rod connector. Get a service manual and use the model number to order the correct parts.

I found some pictures of the outboard I have the pics are the same exact motor to a tee. but the motor has that oval plate on the side and the outboard is supposed to be a 76. So I don't know what the year really is.

Re: 1973 Evinrude impeller change need help..

Well, the hood is a 1973. But that is a simple thing to swap. The midsection and lower unit are definatly not a 1973. If only it could talk.

Those welsh plugs are easy to remove without damaging them. I could post how to do it, but there may be some young wannabe thieves reading this.
