As a staple of the vintage boating era, the Chrysler 105 provided a high power-to-weight ratio for runabouts and early performance hulls. However, because the brand was later absorbed into the Force Outboard line, many owners struggle to find verified technical specifications and compatible replacement parts. This guide uses primary-source data to break down the technical DNA of the 105 and provides verified specs for the Chrysler fleet.
Is the Chrysler 105 a Good Outboard Motor?
The Chrysler 105 is generally considered a "workhorse" of the 2-stroke era. While it lacks the fuel economy and quiet operation of modern EFI engines, its cast-iron and high-grade aluminum construction makes it durable if maintained. The main drawback for modern owners is the Magna-Power ignition system, which can be difficult to troubleshoot. However, for enthusiasts who appreciate mechanical simplicity, the 105 is easy to repair with basic hand tools.
What Is the Fuel Mix for a Chrysler 105 Outboard?
For standard operation, the Chrysler 105 requires a 50:1 gas-to-oil ratio using TC-W3 certified 2-stroke marine oil. It is recommended to use 87 or 89 octane unleaded gasoline. If you are breaking in a newly rebuilt powerhead, a heavier 25:1 mix should be used for the first 10 hours. Avoid high-ethanol fuels, as ethanol can rapidly degrade the vintage rubber gaskets and fuel lines used in these engines.
How Do I Fix Ignition Problems on a Chrysler 105?
Ignition failure is the most common issue reported by Chrysler owners. If you have "no spark" across all cylinders, the culprit is often the CD ignition module or low battery voltage. The Magna-Power system requires at least 9.5V during cranking to trigger the sensor. If your module has failed, many owners perform a points-to-electronic conversion using aftermarket kits, which eliminates unreliable vintage electronics.

Are Parts Still Available for Chrysler Outboards?
While the manufacturer discontinued OEM parts decades ago, the aftermarket for Chrysler outboards remains robust. Companies like Sierra Marine and CDI Electronics continue to manufacture essential service items, including impellers, carburetors, and ignition coils. Additionally, because Chrysler became Force Outboards, many parts from 1984–1992 Force models are directly compatible with the Chrysler 105.
