I recently purchased a 2005 sun tracker party barge and it has a mercury 90hp 4 stroke outboard on it serial# 1B103481 90 ELPT 4S with 8 pin harness. This is my first outboard so I have a lot of questions.
1. the valve shim appears to have gotten of place and nicked the side where it sits, is this an easy repair?
2. whats the best way to clean the carbs I have read that these motors have really small jets that clog easily?
3. the prior owner had the pontoon in a slip and the outboard is covered in gunk ? best way to clean this off ? I think the cowl and legs are plastic or fiberglass hard to tell.
4. whats the best service manual I can get so I can replace the head ? oem? seloc?
5. I'm a pretty good mechanic with cars (17 ASE's) but outboards are foreign to me thats why I always stuck to I/O.
6. if the motor is trashed what year mercury 4 strokes can i get that matches the 8 pin harness ? - I really dont want to have to re-rigg the pontoon with new throttle and steering cables and controls.
7. Is there a website that will tell me all the specs on this motor ie parts,maintenance etc
