Good morning everyone, I've been reading this site for a while now and I have a question I'm looking for help with. I was given a 1985 Evinrude super 25 tiller, super low hours and only fresh water used. My problem is that it is a short shaft and my boat needs a long shaft. My question is what are the exact parts I need to look for? Exhaust housing, drive shaft, water tube and shift linkage, anything else? I know it's a lot of questions for my first post, I appreciate any help with this.

You are better off selling that and buying a motor with the long shaft because you pretty much need to replace everything under the powerhead
 
Flyingscott - are you sure? Is this a model that uses the lower end 5" spacer like the 15's? If so, he just needs the kit.

1985 is the first year that evinrude changed to through prop exhaust for the 25 uses the same bottom end as the 35 hp that has the 5" extension cast into the center housing. If you don't have through prop exhaust you don't an 1985
 
I have a 1996 25 hp that has through the hub exhaust and the 5" spacer when it was converted to long shaft !!!!----So the 5" spacer piece is available for the newer models.---------Factory original long newer models do not use the spacer !!!
 
0396707 KIT, G-CASE EXTN thats your part # price is $510 thats why when people come in my shop and want this done I talk them out of it. that price is only the exhaust housing extension and watertube. You still need the driveshaft another 274 dollars and the upper shift shaft is the one that needs to be changed 5" longer.
 
disregard my last i saw you put your model number and you caught a break your uses the old style lower unit which means those are available for cheap sorry about that
 
Thanks everyone for your help sp far! Since I got this motor for free, putting some money into the conversion wont hurt too bad. I'm sure I'll have more questions as I go along. Thanks again.
