I had a classic vst issue with a 2001 F115 TXRZ not able to go over 3500 rpm. I took the boat to a local Yamaha dealer and for them to clean VST replace screen / filter. I even brought them cleaned / flowed fuelinjectors to replace as well. They called and said my trim caps and ram were leaking...
I just installed a 1996 Johnson 115 J115SLEDR (looper) to replace my 1982 crossflow. I used adapter harness 176349 so I could use my old controls and it was a simple plug N play until I got to the tilt trim. It will TnT locally at the engine but not through the controls.
From the controls the...
The boat is a 1987 Aqausport 170 with a 1982 Johnson J90TLCNB. I have two batteries on the boat and while replacing the batteries I accidentally landed three ground wires onto the positive side on the port battery. I corrected this but now the engine turns over fine but never hits. The rectifier...

Re: thermostat question
From my experiences over the years your thermostat issue would not effect the idle as significantly as yours (600 rpm). It's pretty safe to say it's in the carb adjustment or possibly a bad gasket sucking air since you had them apart. I have replaced failing power packs...
Re: How does the T-stat Pressure Valve work
The pressure valves or poppet valves also control water flow but do so from pressure instead of temperature. In the picture you can see the springs will be going into the power head and hold constant pressure on the poppets and they seat into the...
Hello- I tried to search this question to no avail.
My question is in regards to a 1982 Johnson 90 "TLCNB" which I ordered coils for. I ordered these referenced from an ignition schematic that mentioned 582106 which i ordered 4 of the latest part number (i think) 584561 for this engine. Once I...
