Have a 2001 Johnson 70hp outboard. Idles fine with muffs on. As soon as I put it in the water it doesnt like to stay running. Dies when in gear. Have found a split hose on the choke solenoid outlet side. Would this create a vac leak straight into the cylinder! Runs fine with some throttle on

May be you might have to adjust your idle a bit, when its in gear its turning the prop so that requires a bit of force. yea any split hose should be repaired. could be linkage adjustments.

I would take it to a outboard mechanic to be on the safe side. Ina car if it breaks down you can walk for assistance but not out on the water. I had a impellar go 2 years ago on my boat and had to be towed back to the wharfe long slow trip.

I always found outboard mechanics have a tendency to tune them a bit lean on the idle, a quick visit to the idle jets with a screwdriver sorts it out. I used to beach launch a lot so there was often no time to hang around warming up a cold motor and trying three or four times to get underway.

You ran it without waterthen pulled the muffs off when underway !I have heard of this beforeonceunfortunately, they forgot to take the muffs off with inevitable result .
