![]() ![]() The Indmar 6.2 Raptor that is the standard engine in most Moomba and Supra boats produces 350 HP and 400 Ft. but they are mechanically the same engines offered to other manufactures by Indmar besides cosmetic packaging differences. Malibu chooses to market that their versions Indmar/Ford engines as having 10 additional Ft. The different versions produce 360, 400, 440, & 575 Ft. Indmar makes four versions of the 6.2L Ford engine that had been used previous versions of the Raptor Truck and can currently be found in Ford Super Duty trucks. This is misleading and all of the engines have higher torque figures than HP. The thing to be aware of is many boat manufacturers, dealers and sales reps represent torque output on Indmar Ford based engines as if it was HP. When the switch was made Indmar started marketing engine torque rather than HP. Indmar, the current engine provider to Supra, Moomba, Malibu, & Tige recently switched from GM to Ford based engines. Here is a chart showing CARB's test data by engine family.Įngine torque is also very important in marine engine performance. We have seen customers confused when comparing actual data provided by Ilmor and CARB to data provided by a marketing department. We note this so new and used boat buyers can look to this data when comparing engines in boats. Indmar's 5.7 Engines produced between 288 and 308 HP but as much as 350 HP was claimed. PCM was claiming 343 HP from an engine that only produced 282 when tested by CARB. Ilmor's GM Based 5.7 was the highest performance GM 5.7 engine from any manufacturer when tested by CARB and produced 320 HP. Kilowatts can be converted to HP by multiplying kw * 1.34. All engines sold in California are tested to EPA standards for emissions and peak output in kilowatts(kw). California has more restrictive emissions standards than the other 49 states. It was decided that the only way to publish real specifications and provide information that would help consumers see thru some of the misinformation from other vendors was to use data from the California Air Resources (CARB). ![]() With their performance heritage and talent, Ilmor told MasterCraft that whatever engine performance they wanted was available but but that performance specifications would not be overstated. Ilmor designed and built the most powerful engine to ever race in the Indy 500 and engines powering Formula 1 world champions. If you are not familiar with Ilmor please CLICK HERE. MasterCraft started offering Ilmor Marine engines in late 2010. Some of the engine and boat manufacturers published HP ratings that have been found to be "optimistic" when compared to scientifically derived test data. There has been a lot of confusion regarding published performance specifications in the Inboard Tow Boat segment. ![]()
