Yup she is over 70 mph... your right its a 185 XLT.. There was a guy in hotboat mag reader rides last month from arizona who was running a 406 ci and 475 hp and getting 78 at 5600 with a 25"
The stock 350 mag 270 hp and a 21 pitch got me 59 mph last year .. now with the new motor I am turning a 24" at about 12% slip and gave me around 72, I am getting a 25" to run next hopefully drop me down to around 5300 rpm... and maybe a mph or two.. she is a wild one to drive., chinewalks like a ***** at WOT, trying a few props to see if that helps... it would be nice to bring it over, but the only way to pull it is with dad's truck and he ain't giving that up for the weekend LOL! I had a few problems with her, shifting problem, fixed that, oil pressure problem, fixed that. oil was bypassin the cooler, filter, stat.. welded up the bypass and now have great oil pressure, now have a oil temp concern.. so it is fun to tinker with it... ofcourse right across the back of it the name "Problem child" fits the boat perfect LOL! With all your guy's fine pocket rockets over there, i can leave mine here... its just a toy compared to your guy's boats.. Hows the sonic running? Saw a pic and she is a good looking boat, sweet new paint..
