Frequently Asked Questions

Recently we have had questions regarding usage, serviceability and some of the specialized components that are a part of your MB Sports Tournament Towboat. Listed below are the questions that are most frequently asked and the recommendations we feel are appropriate. These are recommendations; the final decision is ultimately the customer's.

Absolutely Not!!!
Carbon Monoxide Poisoning is a silent killer. Fresh air is your only protection. Also, you should always turn off your engine when you are not moving. DO NOT idle for long periods of time.

No, the gauge is semi-accurate, to completely empty the tanks you must remove the ballast tank plugs after loading your boat on the trailer and let them drain. On 2009 models forward, you can open the transom valve.

Yes, the MB Sports ballast system is designed to empty in 30-60 seconds with the boat on plane. The factory equipped plug and play bags will empty into the hard tanks and out of the boat through the quick fill ballast valves.

No, always empty your tanks before towing. The trailer is NOT designed to carry the extra weight.

No, it is best to tow with a towable boat cover only if you are traveling long distances and are unsure of road and weather conditions.

The Raptor 400/440 requires a minimum of 89 Octane. The Roush Supercharged Raptor 575 requires 93 Octane or higher.

Engine and transmission should be serviced after the first 10-20 hours. After the initial service it should be done once a year or 75 hours regardless of the number of hours used during the season. Consult your Indmar Service Manual for specific service milestones.

Grease lightly 2-3 times a year, over greasing can cause your boat to steer or turn hard.

Indmar uses and recommends a semi-synthetic oil meeting the API rating of SN for use in all its engines. Consult your Indmar Service Manual for specified fluids.

Any good boat soap or mild dishwashing liquid soap works great (1-2 capfuls of liquid soap to one gallon of water). Please use generously and change towels often. Rinse with water and dry immediately. Wash the boat in a shaded area, trying to avoid direct sunlight.

Be sure your tires are filled to maximum listed capacity when cold. Low tire pressure builds heat, causing excessive tire wear and in some cases can cause tire failure.

The trim tab is used to assist the boat in getting on plane.  Once the boat is on plane, the trim tab should be retracted to a position between 0% and 29%.  It is not intended to be deployed at 30% down or more above speeds of 25 MPH.  Doing so can cause failure and potential damage to your boat that is considered abuse and not covered under warranty.

It is the owner’s responsibility to check the bolts on your wakeboard tower, speakers, racks and any other bolt-on accessories. This equipment absorbs a tremendous amount of energy traveling along the highway. The shoulder of the road is especially abusive to your boat; its components and your trailer. Please check you boat and trailer periodically.

Buddy Bearings on your trailer axles do NOT require excessive grease. When used correctly you will only need grease 2-3 times a year. Use a low-pressure grease gun. If insert rocks from side to side, do not grease.

Swim steps are made for entering and exiting the boat. DO NOT OVER LOAD platform (500 lbs. max.) when using. Never use brackets as tie downs.

Towers are designed for wakeboarding and surfing only. Never use to waterski or pull inflatables, etc. The tower could cause bodily injury or death if failure occurs by overloading.

Never overload your boat with excessive weight. 16 person maximum on any MB model.

Towing your boat with the bimini top deployed will void the warranty. The bimini top is not designed to withstand the force generated when towing at highway speeds. Always collapse your bimini top and stow in a safe location before trailering your boat.
