#### **Cons:**

1. **Higher Upfront Cost** Compared to some generic or aftermarket engines, Honda s premium branding comes with a higher initial purchase price.

2. **Limited Availability of Parts** While Honda parts are widely available, finding specialized or older-model components may require ordering from distributors, which can delay repairs.

3. **Potential for Overheating in Heavy Loads** Like many marine engines, the 08C35 can struggle with prolonged heavy loads or poor cooling, which may require additional cooling systems or regular maintenance checks.

6. **Noise Under Load** While generally quieter than competitors, the 08C35 can become louder under heavy throttle, which may be noticeable in smaller boats.

7. **Maintenance Costs Over Time** While reliable, Honda engines may incur higher maintenance costs if not serviced regularly, particularly for components like water pumps, impellers, and seals.

8. **Limited Customization** Unlike some performance-focused engines, the 08C35 is designed for reliability rather than high-performance tuning, which may limit modifications for speed or power increases.
