Glad you are having good luck with it... That sensor in the air box is the air temp sensor. You can just twist the whole sensor about 90 degrees and it will pop out of the air box still connected to the lead. Just don't want you to break that delicate wire connector unplugging it from the sensor. I haven't worked on these things since they came out so don't know if NGK makes and acceptable equivalent for the original Champions. The plugs should be indexed even on your engine. This is a royal pain to do because some plugs won't index properly when correctly torqued. You sure don't want to overtighten the plug (or leave it loose) to index the plugs properly. But yeah, the plugs are an issue in these things for sure, and expensive. Keeping that fuel clean and free from water is key, like you say. Don't forget to check the oil tank for water annually as well. The oil pressure sensor doesn't know the difference between oil and water!
I have a 99 115. Same as yours. You should be running Champion 7712 plus. .30 gap You covered most of what keeps these alive. Premium fuel, change fuel filter yearly, plugs every 2 years, and run a high quality synthetic oil like XD 100 or amsoil hp marine

Repair any compromised wires, and make sure none of them (including battery cables) are routed near any moving parts (shift/throttle linkages) make sure all connections are tight.
@@ryanfavreau6767 so after looking at the motor once I got it out of the water I found that there's a fuel leak on one of the lines it was leaking on to the spark plug wires causing it to burn computer wires seems to be ok but all the spark plug wires are done.
@@ryanfavreau6767 sorry it's been so long so I fix all the wires back got it to start now not taking reverse then to off the lower unit to check and see if there's something wrong but nothing was wrong with it shit fine when I took it down I even tried a different lower unit something happened,so now I went and check the cables they were shifting fine once I took them down now I'm kinda stuck at the moment.
@@kenwatkins5660 You can make a "fine adjustment" of the shift cable where it enters the motor (on the right side, take the little cover off). If that doesn't work, the shift rod (that goes down to the gearcase) may be bent or the two o-rings "gunked up" (pushing down shifts into reverse). I had all three on my 115
If you would index your plugs they would last longer it's whole reason for indexing if the gap don't face the injector they foul...on top of that you will have a carbon problem...anyway that's why your plugs don't last!

The 115s are solid. I bought one and have been running it all summer. Starts on the first crank and tops the boat out at 43 MPH no issues.

That part that is connected to the 'silencer' is the air temperature sensor that sends that data to the ECU.
No it's the mass airflow sensor. It reads how much air goes into the cylinders
@@SwishRecordsInc "Life's Adventures" was correct. It is an air temp sensor.

air box on my unit wont connect properly to the six rubber sleeves. any ideas? Fuel lines obstructing? Is there a mod?

I actually called my local marina and ngk and thats the plug they told me to use

@@sofaking777777 I agree, I am Evinrude certified, no NGK
Definitely champion plugs
@@addismultitasking3504 9 out of 10 old school Evinrude mechanics will say Champion. At least thats what they been telling me for years.
Any thoughts as to how to get at the linkage needed to disconnect the lower unit?
Are you able to delete the oil injection and just use mix gas on these motors?
Im not sure, Ive done it before but not this motor
Hi, what type of Ngk plugs You install?
just go to ngk website and you'll find the correct plug for your motor I usually use the Platinum tip the ones
Do you know how many stroke 150hp model 97/99?
It's probably a 2 stroke
Can you provide the link to order the fuel filter
I have a 2000 150 and all the wires burnt out on one side of the motor what do I do
Ive read that the 115 is the only good FICHT they made. Lots of problems with the higher hp ones

I do index the plugs, but you have to buy 10 of them and use the ones that line up the closest
I still replace them every spring, runs perfect all summer. Have a great new year
Happy New Year... Thank you.
