    Does the 15hp 2004 have an altenator?

    I don't have the specs on this model. I wasn't able to locate it in the online manual. Would an altenator be standard on the 2004 electric-start model, or an option? Thanks.

    Does an Electric start motor have a charging system for the battery?

    Will an electric start motor automatically charge my boat battery if connected to it, or do they only drain power from the battery and not recharge? If the johnson doesn't come with an automatic charging system, do you know if any other models do (i.e evinrude), other brands, or can it be...

    Johnson short vs. long shaft conversion

    Quick question. I know the Johnson 9.9 / 15 model 2 strokes were basically identical. If I had two motors, one a 1992, the other a 1996, or a 2004 for that matter, could I interchange the long shaft extension parts between the two? I.e. the longer drive shaft, shift linkage rod, water tube...

    1992 Johnson 15hp air silencer question

    I recently pulled the air silencer off of my motor and noticed a hole in the air silencer that doesn't look "stock". It appears the previous owner modified it, however it appears to run pretty well as is. The hole may be stock, if so it appeas to have been enlarged (for better air flow I...

    Johnson 15hp - hard starting when cold

    When the engine is cold (has been sitting overnight), it takes about 5-6 pulls to get it started when using the starting procedure from the manual. Once it is warm, it will start on the 1st pull.<br /><br />The engine is a 1993, which I purchased last year. Runs great otherwise. I have not...

    1993 Johnson 9.9 hp - Water Pump telltale not working

    Bought the engine at the beginning of last season for a good price. It was used in saltwater, but supposedly flushed out routinely.<br /><br />Upon purchase I changed the lower unit oil, and rebuilt the water pump, and adjusted the shift detents so it shifts smoothly.<br /><br />Used it about...
