Okay so I got this motor from my uncle. This is my first boat ever and am super pumped. I have some mechanic skills mostly from working on my car doing transmission swaps, shocks & springs, etc. The motor has est. less then 100 hours on it. He has had it since 1998 and ran it a couple times, 4-5 times, a summer in freshwater only, engine never seen saltwater to our knowledge.

In '98 he had the carb rebuilt by a Evinrude dealer. I don't think he did much other maintenance on it but it always ran good for him. I got it from him 2 years ago. When I took it out with him in 2004, the high end of the carb seemed to need adjusting, but other then that it wasn't too bad....although couldn't plane out with a 14' MFG and 3 adults.

Then it sat for 2 years with nothing done to it (long story but mostly licesne and registration related). Last weekend I finally got all that taken care of. I started it up with the muffs on and here are the issues as I see them. I would like to know where to start to get this great motor back to its peak potential:
- engine started right up with the choke out, but wouldn't stay running with choke in (still using 2 year old gas).
- when running with choke out it was "sputtering" alot. like it was starved for air or the carb is gummed?
- the throttle won't go past the "start" position, which looks to be about 1/2 way through the throttle range
- water from the engine in the driveway had significant oil in it (might just be a 2 stroke thing....not much experience with 2 stroke engines)
- when done, the engine leaked oil for about 3 weeks...slowly. When running it was leaking more consistantly. Also the oil was almost a thick milky gray color coming from the lower unit.
- seems to be some oil leaking from the gasket between the lower unit and the 5" extension that came with this model (33553)
- peeing seemed decent strength (but I don't have much of a reference point)
- electric choke doesn't work, had to manually do it.

I was going to start with something small like replacing the water impeller to get more familiar with the engine, but I don't know where to start. Should I just take it to a dealer and have them do an overhaul?

Any advice is much appreciated.

1st go to the engine faq forum (top of this page click boating forums) read "awakening a sleeping outboard" sound like the seal are gone in the lower unit. the milky gray is lubeoil and water. the throttle will not go past start until it is put into gear. do not over rev the engine the stop is for that reason. you due for the impeller, carb rebuild with new kit and float., get rid of the 2 year old gas. all new fuel hoses are inorder also. the choke has 3 settings pull all the way out, is manual choke, in 1 click let's you uese the remote choke button, all the way in is totally off. thats just for starters,, if you have a concern or a question or just not sure, ask the question. better to ask than mess up a good engine.
