Mercury Marine 300HP ProXS Outboard - DTS Start Extra Long Shaft

Pro XS
For competitive tournament anglers or boaters who simply crave speed, the choice is simple. No other outboard goes from zero to wide-open throttle as fast as a Mercury Pro XS® engine.

Run with the motor that continues to win while establishing new standards for performance. Competitive anglers powered by Pro XS® outboards have won more bass fishing tournaments than all other brands combined. With lightning-quick acceleration, blistering top speed, legendary reliability, and lightweight design, Pro XS has everything you need to travel farther, faster, and harder.

Forget lucky. Be fast. 
When every cast makes a difference, Pro XS outboards provide a powerful competitive edge. They use exclusive components and tuning to amplify speed and performance. They are the product of hard work and precision engineering. There is nothing lucky about it.

Move and be moved
Whether you run a bass or multi-species fishing boat, flats skiff or pontoon, Pro XS outboards generate performance you can feel. Even the Redline Red graphics package has the look of a champion – for anyone who demands an elite boating experience.

Pro XS powers champions
No matter whether you compete as a professional or want to win every weekend, the technology behind Pro XS outboards gives you a serious leg up. Their high-output alternators help keep batteries charged. Advanced fuel systems optimise efficiency so you can explore farther on each outing.

Pro XS advantages:

1. Efficient all-around performance: A host of efficiency-enhancing features such as Advanced Range Optimisation (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimise fuel economy so you can get more done on every tank.
2. Squeezing speed from fuel: Mercury V8 and V6 Pro XS models transform every drop of fuel into performance to deliver excellent economy at cruising speed and wide-open throttle.
3. Tournament-winning torque: More displacement delivers more torque and transient spark technology optimises spark timing to boost that torque during hole shot.
4. Smart?charging: A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.

Features:

• TorqueMaster gearcase: The lightweight TorqueMaster gearcase (featured on select V8 models) has a 1.75:1 gear ratio and a robust 1.25 inch diameter prop shaft designed for semi-surfacing, high-speed applications.
• Transient spark technology: Transient spark technology electronically adjusts the ignition timing of the engine as needed. This subtle, automatic change produces additional torque for faster hole shot and acceleration.
• Adaptive Speed Control: Adaptive Speed Control maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle lever position – a first for the outboard industry.
• Extra charging power: A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.
• Performance-tuned exhaust: The exhaust tone has been fine-tuned to provide a brawny performance-inspired sound quality that is unmistakable on the water yet quieter than competing high-output engines.
