whatsup everyone. i just purchased my first boat with a 2 stroke 25 hp Johnson outboard on a 81 14' cruiser. i need some help identifying the year and if you guys could give me some tune up tips that would be great! i took it out yesterday and it started first pull. when letting off the throttle coming to a stop the boat would stall.. then take a minute or two before it would start again. it also seemed like it might of been lacking a little power. there were 3 people in the boat and we didn't go 100% full throttle being i want to tune it up. thanks for the help. heres some pictures to help you guys with my questions.

I beleive it's .030. What kind and part no plugs did you get?

Not to sound like a smart *****, but your best buy would be a service manual. It will give you all the information you can ask for. Also read the "TopSecret Files".
