Afternoon all,
Writing from the shores of Lake hickory in North Carolina. I just purchased a 1993 19 ft Seaswirl with a 175hp Fast Strike last night. After looking the boat over inside and out and taking it for a ride on the lake AND checking compression in all 6 cylinders I bought it. My question is based on after pulling all 6 plugs and noticing everyone of them was on the dark side and a little wet with oil. All cylinders had at least 120 to 125 psi for compression. The motor at startup coughed a little and stalled twice but after warm-up it ran great and idled just as good. But I thought, and owning several different 2-stroke motors in my life but never a 2 stroke boat motor only jet skis, that this Johnson probably needs a tune-up. The owner I bought it from said the boat hadn't been run in a few months and been to the lake in a longer amount of time. The engine is oil injected from a remote tank not pre-mix. The plugs looked to me like it was running rich or the oil injection system might need to be adjusted. I definitely know I need to get a owners manual for the motor AND a service manual. I only know the boat is a 1993 and I do not think this is the stock motor that came with the boat. How do I know what model and year the engine is to be able to get the right manuals and where would I get them also? I want to be able to tune it up myself and also check lower unit oils or anything else that needs proper attention. The motor like I said, ran very well, it was just the plugs were not the optimum color and a tad wet. I never did pull the plugs after we got back from the ride. mayeb they were a different color then.
Anyway, model number and year, how or where can I find that on the engine and where is the best source for factory manuals?
Thanks
Sid
