Hey I was looking at active topics and saw a post about the new Nitro z-7s claiming their fastest speeds with the new 150 xs is like 65, and previous models only went 60-62 mph. I dont own a Javelin any longer, and I cant recall the model, but I had a 1991 17-18 ft boat, with a johnson 150 and digital speedo read I was going 65-68mph with some stuff in the boat, motor blew up (oil tank failure) I gotta 99 johnson 150 and put that on there and was hitting speeds of 70-72 with the wind to my back. No jack plate. Are these realistic speeds for that old boat? I sure thought it was fast back then, had the boat for 4 years back in 1998. Miss it, rocking a 18' duracraft now with 50hp (top speed 36 )
