On Episode 153 of Finnegan's Garage, Mike Finnegan and David Newbern search for more speed out of their LS-Swapped jet boat. The 1976 Rogers Bonneville TR fiberglass jet boat is powered by an LS6 engine with Mast Motorsports cylinder heads, a Holley Hi-Ram tunnel ram, and dual Holley double pumper carburetors. The quest for more speed came from making adjustments to the jet drive hardware. The guys also repaired the trailer, which needed a dozen holes drilled in it and six u-bolts added to it for strength. Of course they did the work right there at the local launch ramp.
