Inconsistent Between Sides - Troubleshooting Guide
How to balance your surf wakes so port and starboard are equal
Problem: Wakes Inconsistent Between Sides
One side of the boat produces a better wake than the other—different size, shape, push, or cleanliness.
Signs of Inconsistent Wakes:
- Port side wake larger/smaller than starboard
- One side has more push than the other
- Different steepness between sides
- One side washy, other clean
- Riders prefer one side significantly
- Different pocket shape or length
- Uneven boat list (leaning more one way)
Common Causes & Solutions
1. Uneven Passenger Distribution (Most Common)
The Problem: More people on one side creates asymmetric displacement
Check This:
- Count people on each side of boat
- Note if more weight on one rear corner
- Check if people shifted during session
Solution:
- Balance passengers left-to-right
- If surfing port side, put 3 people in port rear seat
- When switching to starboard, have passengers switch sides too
- Don’t leave 4 people on port side when surfing starboard
Proper Distribution:
- Surf side: 3 people in rear corner
- Off-side: 0-1 person max
- Bow: 1-2 people, centered
- Center: People can stay center
Test: Switch passengers and re-test both sides.
2. Asymmetric Ballast Fill
The Problem: One side’s ballast tank not filling fully
Check This:
- Verify fill levels on both rear tanks
- Check fill times (should be similar)
- Look for leaks on one side
- Inspect pump operation
How to Check:
- Empty all ballast
- Fill surf-side rear, time it
- Empty and fill off-side rear, time it
- Times should be within 10% of each other
Solutions:
- Uneven fill: Check for clogs in lines, weak pump
- One side slow: Inspect pump, check for kinks in hoses
- One side doesn’t fill fully: Check vent lines, look for leaks
Manual Adjustment:
- If one side consistently weaker, fill that side to 100%, other to 90%
- Use asymmetric ballast settings to compensate
- Document what works
3. Asymmetric Wake Plate Settings
The Problem: Wake plates not set equally on both sides
Check This:
- View wake plate settings on display
- Some boats show left/right separately
- Verify both sides at same percentage
Solution:
- Set both plates to 50% (neutral)
- Test both surf sides
- If still uneven, use asymmetric adjustment:
- Weaker wake side: Lower plate by 5-10%
- Stronger wake side: Raise plate by 5-10%
Modern Systems: Many boats auto-adjust plates when surf gate transfers—verify this is working.
4. Debris on Surf Gate
The Problem: One surf gate has weeds, zebra mussels, or debris affecting deployment
Check This:
- Inspect both surf gates visually (stop boat safely)
- Look for weeds, rope, debris caught on gate
- Check for marine growth (zebra mussels, barnacles)
Solution:
- Clean both gates thoroughly
- Remove all debris, weeds, rope
- Scrub off marine growth
- Verify smooth deployment
Prevention: Clean gates after every session, especially in weedy water.
5. Unequal Surf Gate Deployment
The Problem: One gate not deploying fully or consistently
Check This:
- Watch gate deployment on both sides
- Verify 100% deployment on display
- Listen for actuator operation
- Check for error codes
Solutions:
- Partial deployment: Clean gate, check actuator
- Slow deployment: Inspect hydraulic lines, check fluid
- Inconsistent: May need actuator service
- Error codes: Consult owner’s manual or dealer
Test: Switch sides multiple times and watch deployment carefully.
6. Fuel Tank Location
The Problem: Fuel tank on one side creates asymmetric weight
Understanding:
- Most wake boats have centered fuel tanks
- Some older models have side-mounted tanks
- Full tank = 400-800 lbs on one side
Solution:
- Centered tank: Not the issue
- Side-mounted tank: Compensate with asymmetric ballast
- If tank on port side, add 10-15% more starboard ballast
- Adjust based on fuel level
- Check your manual: Note tank location
7. Propeller Walk/Torque
The Problem: Prop rotation creates slight list to one side
Understanding:
- Inboard props rotate (typically clockwise)
- Creates slight lateral force
- More noticeable at surf speeds
- Affects one side more than other
Solution:
- Usually minimal impact on modern boats
- Compensate with asymmetric ballast (5% difference)
- Adjust wake plates asymmetrically (5-10% difference)
- Some boats have torque compensation built-in
Check: If one side consistently weaker despite other fixes, prop torque may be factor.
8. Hull Damage or Modifications
The Problem: Physical hull issues causing asymmetry
Check For:
- Damage to one side of hull
- Uneven swim platform extensions
- Aftermarket modifications on one side
- Repair work that altered hull shape
Solution: Requires professional inspection and possible repair.
When to Check: If inconsistency appears suddenly after impact or grounding.
Step-by-Step Troubleshooting Process
Step 1: Check passenger distribution
- Balance people left-to-right
- Test both sides
- Still inconsistent? Continue to Step 2
Step 2: Verify ballast fills evenly
- Check fill times and levels
- Empty and re-fill both sides
- Still inconsistent? Continue to Step 3
Step 3: Clean both surf gates thoroughly
- Remove all debris
- Test both sides
- Still inconsistent? Continue to Step 4
Step 4: Check wake plate settings
- Set to 50% on both sides
- Test both sides
- Still inconsistent? Continue to Step 5
Step 5: Verify surf gate deployment
- Watch deployment on both sides
- Check for full actuation
- Still inconsistent? Continue to Step 6
Step 6: Use asymmetric adjustments to compensate
- Adjust ballast, plates, or both
- See “Asymmetric Tuning” section below
Asymmetric Tuning Guide
If mechanical systems check out but wakes still differ, use asymmetric settings:
Scenario: Port Wake Larger Than Starboard
Adjustments:
- Reduce port-side ballast by 10%
- Increase starboard ballast by 10%
- Or: Raise port wake plate by 5%, lower starboard by 5%
Scenario: Port Wake Smaller Than Starboard
Adjustments:
- Increase port-side ballast by 10%
- Reduce starboard ballast by 10%
- Or: Lower port wake plate by 5%, raise starboard by 5%
Scenario: Port Wake Cleaner, Starboard Washy
Adjustments:
- Check starboard surf gate (likely dirty/debris)
- Raise starboard wake plate by 10%
- Reduce starboard ballast by 5%
Scenario: Port Wake Steeper Than Starboard
Adjustments:
- Raise port wake plate by 10%
- Lower starboard wake plate by 5-10%
Documentation & Settings
Keep a Log: Record settings that produce balanced wakes for your boat:
| Side | Surf Tank | Off-Side Tank | Bow | Center | Plates L/R | Wedge | Speed |
|---|---|---|---|---|---|---|---|
| Port | 100% | 70% | 75% | 100% | 45%/50% | 75% | 11.2 |
| Stbd | 90% | 75% | 75% | 100% | 50%/45% | 75% | 11.2 |
Note: Your boat may need slight differences to achieve balance.
Common Scenarios
Scenario 1: Perfect Port, Weak Starboard
Most Common Cause: Passengers stayed on port side when switching
Solution:
- Move passengers to starboard rear seat
- Balance weight side-to-side
- 3 people starboard rear, 1-2 bow, 0-1 port
Scenario 2: Both Sides Good But Different Shape
Likely Cause: Asymmetric wake plate deployment or settings
Solution:
- Set plates to neutral (50/50)
- Test both sides
- Adjust asymmetrically if needed
- One side may need 5-10% difference
Scenario 3: Inconsistency Developed Over Time
Likely Causes:
- Ballast pump weakening on one side
- Marine growth on one surf gate
- Debris accumulation
Solution:
- Service ballast system (check pumps, lines)
- Thorough cleaning of both gates
- Inspect for physical wear
Scenario 4: Brand New Boat, Inconsistent From Day 1
Likely Causes:
- Factory settings need adjustment
- System calibration needed
- Design characteristic of hull
Solution:
- Document differences and settings
- Visit dealer for calibration
- May need asymmetric settings permanently
- Some hulls favor one side slightly—compensate accordingly
Advanced Diagnostics
Ballast System Test
Full Diagnostic:
- Empty all tanks
- Fill port rear, time it (should be 10-20 min)
- Empty port rear
- Fill starboard rear, time it
- Compare times (should be within 10%)
If times differ significantly:
- Check pump strength (weak pump on slower side)
- Inspect hoses for kinks or restrictions
- Look for leaks
- Check vent lines
Surf Gate Test
Full Diagnostic:
- Deploy port gate, watch carefully
- Note deployment speed and completeness
- Retract port gate
- Deploy starboard gate, watch carefully
- Compare
If deployment differs:
- Check actuator function
- Inspect hydraulic lines
- Look for binding or resistance
- May need service
Pro Tips
✅ Passenger discipline: Train your crew to switch sides with surf side
✅ Document it: Every boat is slightly different—record what works
✅ Clean regularly: Debris is a common and easy-to-fix cause
✅ Test systematically: Change one thing at a time
✅ Accept minor differences: 5-10% difference is normal and acceptable
✅ Check fuel level: Running low on one side? Fuel shift affects balance
✅ Seasonal check: Start of season, test both sides and adjust as needed
When to See a Dealer
Professional help needed if:
- Ballast system not functioning properly
- Surf gate actuators not deploying
- Significant asymmetry despite all adjustments
- Sudden change after impact or grounding
- Error codes appearing
- Mechanical noises during deployment
Quick Reference Checklist
Check These First:
- Passengers balanced left-to-right
- Both surf gates clean and debris-free
- Both ballast tanks filling completely
- Wake plates set equally (unless using asymmetric tuning)
- Surf gates deploying fully on both sides
- Same wedge setting for both sides
