15hp, 25hp, and 30hp

They all use the same powerhead, so what are the differences? Can I turn the 15hp into a 30hp with different injectors and computer mapping?

Re: 15hp, 25hp, and 30hp

There are usually some differences between the hp ranges in the same engine family besides the EMM programming. Of course with the EPA Federal regulations, manufacturers, dealers, mechanics, and individuals are not allowed to modify or change emissions or power outputs on recreational outboard motors.

***************

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.

The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
