Great boat . Has no hook in the bottom design. 45 mph sounds slow , depends on what engine it has . Mild 460 bbf you can expect up to 50. My boat has the LS-6 and got it close to 60 with light load and repitched prop. Make sure you have a proper
V-drive pan with baffle and trap door,like Dooley . Most of these boats came with crate engines and wrong [ automotive ] pans. There's no limit on speed [ I'm sure it would run rock solid 80+ ] providing you have a monster engine. The hull is super strong [ 4400lbs dry] with four full length stringers. Gary Garbrecht ran one with twins well over 80 mph in the late 70's.Make a visit to Greg Shoemaker ,he rebuilt that one .Jim Wilkes used to be a spectra dealer,so he should know a lot about them.Price wise they run as low as 7 K , high as 25 K , depending on condition and power plants .I would jump on it since it's the desireable low cabin version.
