Re: HELP.. Mercury 850 (85 HP) Issues
Hello Jimmy, My main problem was the switchbox after spending much time with the boat on the trailor in the water trying to link and sync i discovered no spark on two cylinders under load then verified by cdi troubleshooting guide. I tried to splice the hooked arm trigger wires but they were to far gone and while the flywheel was off i went ahead and changed the stater with a used cdi open air unit found on ebay. I think it came off a 50 horse.
switchbox p/n is 114-5772
trigger p/n is 134-6454 (hooked arm)
stator p/n is 174-5454k1
found these p/n's here:

this stuff should be right here on iboats or roll the dice and check used on ebay or elsewhere.
i would check with the cdi troubleshooting guide first though it may save you some cash instead of throwing parts at it. rule out link and sync and fuel problems too
