I just bought a boat with a 70hp johnson Seahorse, mid 80's model i think. The motor hasn't been run in a year and the seller told me that i might need to empty the gas tank and put in new. Well i didn't empty the old gas out and i put in about 3 gallons to top the tank off.. I put it in the water and it started up and ran good, i took off up the lake rode a mile or so and it started bogging down and the rpms was going up and down, up and down and i could smell an old gas smell. After a few minutes of that the motor started running good again. This happened several times today... Does this sound like a Old Gas problem or a carburetor problem.... thanks...
