OXE Diesel Outboard Comparison: 150, 200, 250 & 300 HP
OXE builds diesel outboards across two engine platforms: a 2.0-litre inline-four that powers the 150–200 HP models, and a BMW-derived 3.0-litre inline-six that powers the high-output 225–300 HP models. Choosing the right OXE comes down to your hull weight, the load you carry, and how much range and top-end you need. This guide compares the range side by side and points you to the right model.
OXE diesel outboard range at a glance
| Model | Engine platform | Displacement | Max torque | Best for |
|---|---|---|---|---|
| OXE 150 HP | Inline-4 turbo diesel | 2.0 L | ~380–415 Nm | Lighter working hulls, RIBs, tenders |
| OXE 175 HP | Inline-4 turbo diesel | 2.0 L | ~380–415 Nm | Mid-size workboats & patrol |
| OXE 200 HP | Inline-4 turbo diesel | 2.0 L | ~415 Nm | Heavier RIBs, commercial day boats |
| OXE 225 HP | Inline-6 turbo diesel | 3.0 L | High | Loaded workboats, twin rigs |
| OXE 250 HP | Inline-6 turbo diesel | 3.0 L | High | Patrol, survey, offshore workboats |
| OXE 300 HP | BMW 3.0L bi-turbo inline-6 | 3.0 L | 680 Nm @ 1,750 rpm | Heavy patrol, offshore, max-load fleets |

The two OXE platforms explained
150–200 HP — the 2.0L inline-four
The 150, 175, and 200 HP models share a 2.0-litre turbocharged, intercooled inline-four diesel producing around 380–415 Nm of torque and a 130-amp alternator. This platform is the efficient workhorse of the range — ideal for RIBs, tenders, and lighter commercial hulls that need diesel economy and single-fuel logistics without the weight or cost of the six-cylinder engines. Parts and service kits for this family are shared across all three ratings (see the 150–200 HP parts).
225–300 HP — the 3.0L inline-six
The 225, 250, and flagship 300 HP models step up to a 3.0-litre inline-six. The OXE 300 uses a BMW bi-turbo configuration that delivers a massive 680 Nm of torque at 1,750 rpm — with over 500 Nm available as low as 1,000 rpm — plus a 180-amp alternator for demanding electrical loads. This is the platform for heavy patrol boats, offshore workboats, survey vessels, and government fleets running twin, triple, or quad installations that need maximum pulling power and range.
Which OXE should you choose?
- Light-to-mid working hulls, tightest fuel budget: OXE 150–200 HP.
- Heavy loads, offshore, long range, high electrical demand: OXE 250–300 HP.
- Multi-engine patrol/fleet rigs: OXE 300 HP for maximum torque per transom.
- Jet-drive / shallow-water operations: ask about the OXE 300 Jet-Tech.

Frequently asked questions
What is the difference between the OXE 200 and OXE 300?
The OXE 150–200 HP models use a 2.0L inline-four diesel with around 380–415 Nm of torque and a 130-amp alternator. The OXE 300 uses a BMW 3.0L bi-turbo inline-six producing 680 Nm at 1,750 rpm with a 180-amp alternator — far more torque and electrical capacity for heavy, offshore, or multi-engine use.
Do OXE 150–200 HP models share parts?
Yes. The 150, 175, and 200 HP models share the same 2.0L inline-four platform, so most parts and service kits are common across the three ratings.
Which OXE diesel outboard is best for a heavy patrol boat?
For heavy patrol, offshore, or long-range work, the OXE 250 or 300 HP on the 3.0L inline-six platform is the best choice thanks to their high low-end torque and 180-amp alternator.
