“Hey, I got an idea…” said the Skipper to his first mate, “Let’s put a 6.2L, 556 HP LSA small block in this old, crappy boat! “Huh?” said his sunburned cohort. “Yeah, it’ll be the first known application of a stern drive, supercharged small block installed in a boat, ” said the Skipper as he snapped open another can of Rainier. At this point even the sun baked buddy was confused and fired back, “You’re cut off!”
A “marinisation” of a car engine requires a host of modifications including cooling, exhaust, fuel delivery, EPA requirements, and hooking the beast up to an outboard drive. The big deal with this install is Michigan Motorz nixes a thru-hull exhaust setup for a thru-prop system with the goal of quieter operation.
With the LSA neatly installed in the scaly old fishing boat, we get to see the finished project cruising quite nicely out in open waters laying down a foamy, v-shaped wake.
Which begs the next question, “why?” According to our research, a crate LSA goes for around $19K and the Mercury Bravo Outdrive goes for about $11K. Even a used LSA yarded out of a old CTS-V ain’t cheap. Has this become the worlds most expensive, sea-worthy Rat Rod? Maybe, but we think the guys at Michigan Motorz used this exercise as a floating “mule” to prove this mega HP, thru-prop exhaust install could be done.
