‘97 Johnson 70 Idle issues

If it still has the 3 vane you have to order the update kit to covert to a 6 vane impeller..It has the newer cover and pop-off springs(432955).
You cannot just change the impeller....

Motor needs bored, all 3 cylinders and needs exhaust bridge mod....see post #7. WSM is best kit and make sure you replace 3 vane impeller even 2 years

What is this exhaust bridge mod....?
