Hey guys, I've got a 1999 Maverick Mirage that needs to be re-powered. Been running a 1999 Yamaha 90 2 stroke. Trying to decide between the heavier F90 or the lighter F70. With the 90 2 stroke, the boat had great hole shot and would run 40 to 41 with a light load. Don't want to lose too much off that with a new motor. I'm afraid the f90 will be too heavy and afraid the f70 will feel sluggish. Any of you guys have experience with this?
