The Sport I am buying comes equipped with a 92 Johnson 25 outboard that hasn't been run in 10 years. I know I'm going to have to do basic maintenance, but what kind of problems can I expect when trying to get this back in running great condition? I am an absolute newbie when it comes to outboards, but I do have a good mechanical background so I should be able to understand what to do. I just have never worked on an outboard before so any heads up would be great! Thanks guys.

Do you know if the engine was winterized before it was put away 10 years ago?

Load the cylinders with oil and leave set for a few days before attempting to turn it over. The cylinders could be dry and a little rusty so the oil will help loosen it up. Good Luck

I highly doubt it was winterized as it was attached to the boat and it is sitting outside. I'll pour oil into the cylinders and do some more research on starting it without ruining it.

For sure then spray some fogging oil into both cyl's before trying to turn the flywheel. If you use regular oil, it will be much harder to get running. I'd also spray some into the carbs while you crank (or pull if it's not elect. start) with the ignition disabled to lube up the reed box and internals. Don't know if that engine is premix, but you could also add (more) oil to the fuel to help with the initial lube.

I will do all of this, thank you. I believe it is an electric start as well. I'm really hoping for the best, but I know it's going to need some TLC before I can go to the lake with her.

Just saw your pic's, engine looks like it's in very good shape outside. Keep us posted on how it goes. If she does start and run on the muffs, you'll want to change the water pump impeller (best to get the whole pump kit) pretty soon, wouldn't run it too long on that old impeller. And changing the lower unit oil would be good too, as well as lubing the grease fittings, etc. But see if she'll start first.

Thanks. I read that the water pump should be replaced in another thread so I planned on doing that as well. Time to start pricing parts!

I'd think about getting it running first, no sense installing a new water pump if the engine is bad mechanically.

After you oil it up some, you could try a compression test, or simply try running it. As others have said, try not to spend any money until you see if it's a viable block. Sometimes the rings will freeze to the pistons after a long period of inactivity. Sometimes running it will knock them loose, sometimes it won't. Stuck rings=low compression. I'm at a very similar stage with my Whaler- engine has been sitting 10 years without proper storage. So far, so good, the compression seems good. I'll try firing it up before buying anything.
