You did not state a year. The 90 Johnson's came in two flavors, the older crossflow and the newer loopers. The 90 degree crossflow weights in at around 301 and the 60 degree looper is around 319.

There were 90 degree and 60 degree looper V4s and the cross flow. My 115 HO is a 60 looper and the heaviest at 375. A 90 carb looper would be between mine and the cross flow.

If I remember right, the Merc will be about 60 pounds heavier. Took a CF V4 off my 16 Baja and put a 2.5 Merc on it, not very noticeable difference in the squat
