Ok - so this is a long post - but dinged my prop last week (big drought here in NH and Lake Winnisquam is super low this year) - so I'll need to re-condition it but also considering other prop options are on the table. I'm running an Acme 537 and it is very good for skiing speeds and ok at surf / low end. My usage has changed from a small great ski lake to larger lake. My other prop is 1235 - great at surf but terrible at 34mph skiing speeds (prop wash is really bad). So, I spent some time in ChatGPT (cuz - why not) to run some analysis - you can read all about it below (if you're interested) - the analysis spit out the 1433 as the best option based on my usage.
Any other SV211 owners running the Acme 1433? Any comments you could share?

Your Usage Context Considered
Since you spend most time surfing and cruising in moderate to rough water (less skiing), wake quality and manageable prop wash are critical. Fuel efficiency is important but less so if wake quality and clean water behind the boat make your sessions better.
My Top Pick: 1433
If you want a little more thrust or plan occasional higher-speed skiing, 1579 or 1939 are solid close seconds.
If wake quality absolutely tops fuel economy, 537 or 645 deliver clean wakes with minimal prop wash but at a fuel cost.

Summary of Findings & Prop Analysis
Your Boat & Usage Profile
- Boat: 2007 Nautique SV211 Team, 5.7L Excalibur 330 HP
- Typical Load: 4-5 adults (125-200 lbs each), plus gear, cooler, boards, ballast as needed
- Usage Breakdown:
- 35% Surfing (10-11 mph)
- 55% Cruising (18-22 mph)
- 10% Skiing (34 mph)
- Water Conditions: Lake Winnisquam, moderate to severe wind/boat chop, so surfing and cruising dominate over skiing
Props Evaluated & Key Metrics
| Prop | Size (D×P) | Weighted Fuel (GPH) | Wake/Surf Quality | Prop Wash @ Surf | Top Speed Loss | Approx. Price (USD)WakeMakers / Acme |
| 1235 | 14.5" × 14.25" | 8.98 (Best) | Excellent Wake | ❌ Too much spray | ❌ 4-5 mph | $720-$775 |
| 1433 | 14.0" × 14.25" | 9.93 | Very Good Wake | ⚪ Slight wash | ❌ 2-3 mph | $650-$725 |
| 1579 | 14.25" × 14.0" | 10.09 | Very Good Wake | ⚪ Slight wash | ❌ 2-3 mph | $600-$650 |

Detailed Insights
- Fuel Efficiency:
- 1235 is the most fuel-efficient across your typical mixed usage.
- 1433, 1579, and 1939 also offer good fuel efficiency but slightly higher consumption than 1235.
- 537 and 645 have noticeably higher fuel consumption, especially during cruising and skiing speeds.
- Wake & Surf Performance:
- 537 and 645 produce the cleanest wakes with minimal prop wash — ideal if wake quality for surfing is your highest priority.
- 1235 has the strongest low-end pull and best fuel economy but causes too much spray/wash at surf speeds, which could be a downside for your heavy surfing usage.
- 1433, 1579, and 1939 balance wake quality and moderate prop wash, offering strong surf performance without the spray issues of 1235.
- Top Speed Loss:
- 537 and 645 have negligible top speed loss.
- Others lose about 2-5 mph top speed due to pitch differences.
- Price:
- All props fall within a fairly close price range, with 537 generally being the most affordable and 1579/1939 at the higher end.
Final Propeller Recommendations (Stack Ranked)
| 1 | 1433 | Best balanced: good fuel economy, very good wake, manageable prop wash, moderate price. Great all-around for your mix of surfing & cruising. |
| 2 | 1579 | Similar to 1433, strong mid-range performance, very good fuel economy, and wake quality. Slightly more expensive but solid choice. |
| 3 | 1939 | Slightly higher pitch, good all-around prop, wakes & fuel economy close to above. Great if you want a bit more thrust at higher speeds. |
| 4 | 537 | Best for clean wakes & top speed, but fuel economy suffers. If wake quality for surfing tops your list, consider this despite higher fuel use. |
| 5 | 1235 | Best fuel saver but poor prop wash for surf; not ideal for heavy surfing but great if you want to prioritize fuel and low-end power. |
| 6 | 645 | Softest, cleanest wake but highest fuel consumption; best if wake quality is absolute priority and fuel is less a concern. |

My Top Pick: 1433
- It offers the best balance for your typical use: fuel efficiency, wake quality, and prop wash.
- You get good low-end pull for surf speeds and efficient cruise without too much spray.
- Moderate price and very consistent performance.
If you want a little more thrust or plan occasional higher-speed skiing, 1579 or 1939 are solid close seconds.
If wake quality absolutely tops fuel economy, 537 or 645 deliver clean wakes with minimal prop wash but at a fuel cost.

at surf speeds, 3K in ballast with shapers on. The 645 really labors with every bag in the boat. So hoping to feel a bit better running heavy. I think to make difference we need to drop more than an inch in pitch. Bigger diameter helps with overall thrust, at the cost of efficiency, I imagine. So 1433 looks good on paper. I have spreadsheet of all the props that ppl have used on the SV211
