2-Cycle TCW III is a high performance engine oil that improves performance and dramatically reduces wear in two-cycle gasoline engines. It’s recommended for use in both pre-mixed and oil injected gasoline two-cycle engines in outboard motors, motorcycles, jet skis, chain saws, etc.

2-Cycle TCW III increases horsepower and reduces fuel consumption, heat, wear and emissions. Its synthetic solvency keeps spark plugs and exhaust ports clean as well. Its performance advantages come from a blend of synthetic oils plus Royal Purple’s proprietary Synerlec additive technology. Synerlec significantly increases the oil film strength for optimum engine efficiency and maximum protection.

Max-Gear

Max-Gear is what all boats from The Boat House run. Longer life for your gears and increased top end speed.

Max-Gear is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls.

Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions, and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.
