good luck with your boat GBM --- when you replace the old 90 Johnson. get down deep in the pocket and replace with a
4 stroke of your choice it will Dang near pay for itself in gas you save. when I got my 4-stroke 90 Yamaha I thought the gas
gage broke on it lol it stayed full for 4 or 5 fishin trips. I called boat place and he said to keep running it it would come to itself.
