I know a few tournament guys that swear by the 150,175 and 200 EFI motors. They say those are the most reliable and fuel efficient Mercs they ever made and the least expensive to maintain. Hope that's true.
Mine is a 2003 150EFI and it's a good running motor.
From Genesis: "And God promised men that good and obedient wives would be found in all corners of the earth."
Then He made the earth round...and He laughed and laughed and laughed!
