Pontoon motor upgrade

I have a 1992 evinrude 40 hp 2 stroke on my pontoon.   I would prefer to just change out the motor to a newer motor.  I would prefer a 9.9-15 hp 4 stroke outboard.   Do I have to stay with Evinrude so the shifter/start etc... work.  And do I have to stay with a 2 stroke for the controls to work or can I go to a 4 stroke.    Boat is hard to get out of the water so I hopefully can change the motors out myself.  Evinrude has been great I just need to know what options I have.   Another question.....are Johnsons and Evinrudes interchangable.

Re: Pontoon motor upgrade



Johnson and Evinrudes have not been the same since 1998, and now Johnsons are no longer being produced.


 For your pontoon boat, you should look into the small hp 4-stroke portables that Evinrude is coming out with, 3.5 to 15hp and electric start and tilt and trim options available on some models. Going from a 40 down to a 15hp is a large drop and you may be disappointed being so underpowered.


The 15HO E-TEC would be a better choice, or the 25 or 30hp E-TECs if you want to downsize.


The E-TECs have a much longer service interval than any 4-stroke so you do not have to pull you pontoon out of the water for the routine servicing of a 4-stroke. Talk to an Evinrude dealer for more advantages and maintenance savings on an E-TEC.

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.
