If you’ve ever stumbled across an old Chrysler inboard and wondered, “Does this thing still run?”—this one’s for you. In a recent episode from Uncle Tony’s Garage, the engine-focused YouTube channel takes a nostalgic and greasy deep dive into the world of Chrysler marine engines. And it’s more fascinating than you’d expect.
Uncle Tony, known for his no-frills, wrench-turning approach to old engines, walks viewers through Chrysler’s marine legacy, from the beloved slant-six to the iconic small-block LA V8s. These weren’t just automotive castoffs—they were dependable, purpose-built marine workhorses that powered everything from ski boats to cabin cruisers.
Chrysler’s Boat-Building Era
Most people know Chrysler for muscle cars and minivans, not fiberglass boats. But from the 1960s into the 1980s, Chrysler Marine and Chrysler Boat Corporation were turning out complete vessels—hulls and engines included. These inboards became a common sight in family boats across North America, especially the 318 and 360 V8s, and marine versions of the slant-six inline engine.
The big draw? These motors were simple, tough, and shared parts with their automotive cousins. This made them affordable and easy to maintain—two traits that helped them outlive many of the boats they were installed in.
What Makes These Engines Special
In the video, Uncle Tony explains what gave these engines their staying power:
- Durable cast-iron blocks and heads
- Straightforward, carbureted fuel systems
- Interchangeable parts with automotive models
- No-frills design that was easy to service
He also highlights the fact that many of these motors are still running today. On forums and in marinas, you’ll hear boaters talk about their trusty LM318 or M360 still firing up every spring after decades of use.
Still Worth Fixing?
Yes, says Tony—and not just for nostalgia. If you’ve got a Chrysler marine engine and it’s not seized or cracked, chances are it can be brought back to life with some carb cleaning, fresh plugs, and new cooling system parts. Rebuild kits are out there, and if you know your way around a Mopar, you’re already halfway there.
And for budget-conscious boaters? These engines often show up in online classifieds for a fraction of the cost of modern powerplants.
