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:

  1. Empty all ballast
  2. Fill surf-side rear, time it
  3. Empty and fill off-side rear, time it
  4. 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:

  1. Empty all tanks
  2. Fill port rear, time it (should be 10-20 min)
  3. Empty port rear
  4. Fill starboard rear, time it
  5. 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:

  1. Deploy port gate, watch carefully
  2. Note deployment speed and completeness
  3. Retract port gate
  4. Deploy starboard gate, watch carefully
  5. 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
  • Speed consistent

If All Good, Try Asymmetric Tuning:

  • Adjust ballast 5-10% differently on each side
  • Adjust wake plates 5-10% differently
  • Document what produces balanced wakes
