Strengths
- 168 KTAS cruise with 250 HP IO-470-N — fastest in middle-era V-tail lineup
- Best-flying V-tail ever produced — light controls, balanced harmony, moderate gross weight
- Fuel injection standard — carburetor ice elimination, better high-altitude performance
- Value sweet spot — meaningfully faster than early Bonanzas, $20k–$40k cheaper than S35
Weaknesses
- 65+ year-old Continental IO-470 cylinders prone to cracking — borescope inspection essential
- Two critical V-tail tail-attach ADs (94-20-04, 91-22-04) require documented compliance verification
- Partial or missing logbooks common — major-event continuity (engine SMOH, prop overhaul) difficult to verify
- Aged magnetos on infrequent-use aircraft develop internal corrosion
Overview
The 1958-1964 Beechcraft Bonanza J35 through S35 series represents the middle era of V-tail Bonanza development -- between the original 1947-1957 "early" Bonanzas (35 through H35, generally 196-225 HP) and the late V35/V35A/V35B (1966-1982). This era saw the transition from 225 HP to 240/250 HP Continental IO-470 engines, gradual gross weight increases (2,950 → 3,300 lbs), and refined avionics integration. Approximately 4,000 examples were produced across the seven-year run.
This middle era is the value sweet spot of the V-tail Bonanza market -- meaningfully faster and more capable than the early Bonanzas, but at significantly lower pricing than V35B examples (which command premium pricing due to 285 HP IO-520 power, late production, and "last V-tail" status).
Variants & History
Variant Breakdown by Letter
| Variant | Years | Engine | HP | Max Gross | Notes |
|---|---|---|---|---|---|
| J35 | 1958 | Continental IO-470-C | 250 | 2,950 | First fuel-injected Bonanza |
| K35 | 1959 | Continental IO-470-C | 250 | 2,950 | Refinements |
| M35 | 1960 | Continental IO-470-C | 250 | 2,950 | Refinements |
| N35 | 1961 | Continental IO-470-N | 260 | 3,125 | +10 HP, gross increase |
| P35 | 1962-1963 | Continental IO-470-N | 260 | 3,125 | Major refinements |
| S35 | 1964 | Continental IO-520-B | 285 | 3,300 | IO-520 introduction, gross to 3,300 |
The S35 (1964) is the first 285 HP Bonanza and effectively the prototype for the V35B engine configuration. S35 pricing trades closer to V35 levels than to earlier J-P variants.
Distinguishing Features (vs Early Bonanzas and V35)
| Feature | Early 35-H35 (1947-1957) | J35-S35 (1958-1964) | V35/V35A/V35B (1966-1982) |
|---|---|---|---|
| Engine | Continental E-185-1/E-225/O-470 | IO-470-C/N (J-P) / IO-520-B (S35) | IO-520-B/BA |
| HP | 165-225 | 250-285 | 285 |
| Fuel system | Carburetor | Fuel injection (J35+) | Fuel injection |
| Max gross | 2,650-2,900 lbs | 2,950-3,300 lbs | 3,400 lbs |
| Useful load | ~900-1,150 lbs | ~1,200-1,350 lbs | ~1,294 lbs |
| Cruise | 152-165 KTAS | 165-170 KTAS | 172 KTAS |
| Avionics era | Pre-modern | Mid-modern | Modern |
The J35 Fuel-Injection Transition
The 1958 J35 was the first fuel-injected Bonanza -- Continental's new IO-470-C replaced the carbureted O-470. This transition was driven by:
- Better high-altitude mixture management
- Elimination of carburetor ice
- Smoother running
- Marginal fuel economy improvement
Fuel injection has been standard on all Bonanzas since. The J35 transition is often referenced as the "modernization" point in the V-tail Bonanza line.

Performance
168 KTAS cruise at 7,500 ft (75% power), 1,100 FPM climb at gross, 13.5 GPH. Service ceiling 19,000 ft. Range with reserves at 80 gallons: 700 NM at economy cruise.
The middle-era V-tail Bonanzas are notably light on the controls compared to later V35s -- many V-tail enthusiasts consider the M35/N35/P35 to be the best-flying V-tails ever produced. The combination of moderate gross weight, ample power, and balanced control harmony is hard to beat.

Valuation Factors
| Condition | Price Range |
|---|---|
| Project / needs engine | $40,000-$60,000 |
| Flying but tired (J35-M35) | $55,000-$85,000 |
| Well-maintained (N35-P35) | $80,000-$120,000 |
| Well-maintained S35 (IO-520) | $100,000-$145,000 |
| Restored / IO-550 upgraded | $130,000-$185,000 |
S35 (1964) examples trade $20,000-$40,000 above J35-P35 examples due to the IO-520 engine and 3,300 lb gross weight. Late P35s (1963) trade close to S35 levels.
ADs & Common Problems
V-tail Bonanza universal concerns apply. J35-S35-specific:
- Bonanza V-tail tail attach AD compliance: AD 94-20-04 (forward bulkhead inspection) and AD 91-22-04 (V-tail fork inspection) apply to all V-tails. Verify compliance.
- Continental IO-470 cylinder condition: 65+ year-old IO-470 cylinders can crack. Borescope inspection essential.
- Magneto condition: Aged magnetos on infrequent-use aircraft can have internal corrosion.
- Logbook completeness: 60+ year-old aircraft often have partial logbook losses. Verify continuity of major-event records (engine SMOH, prop overhaul, ADs).
- Bonanza Society participation: Aircraft with documented Bonanza Society pre-buys and ADs-complied paperwork command premium pricing.
