What is the difference between amps and cranking amps?
The difference between Peak and Cranking Amps is that Peak Amps measures the maximum power (current) a jump starter can discharge (typically in a very short burst) while Cranking Amps measures the sustainable power a jump starter can discharge for an extended period of time, typically 30 seconds.
What is the difference between marine cranking amps and cold cranking amps?
Cold Cranking Amps (CCA) is a test conducted at 0 F (-18 C) for 30 seconds without falling below 7.2v at the battery’s CCA rating. Marine Cranking Amps (MCA) is a test conducted at 32 F (0 C) for 30 seconds without falling below 7.2v at the battery’s MCA rating.
Which is the correct battery for a Mercury outboard motor?
Battery Ratings Note: These are minimum engine specifications. Additional electrical loads from the boat will require larger batteries. For assistance, please use the Help Desk. You must log in or register to view replies here.
How big of a battery do you need for an outboard engine?
40 – 140 HP engines can use a 360 CCA battery 150 – 300 HP engines require a 500 CCA battery you can use a battery with a higher CCA rating than specified, but not less than the numbers listed. In other words you can’t have too much capacity — just too little.
What is dry weight of Mercury Marine 115elpt?
The 115hp weighs 20 pounds less than its closest four-stroke competitor, making it the world’s lightest low-emissions outboard in its power range. Dry weight specification is for the lightest-version model. Comparative weights refer to base engines without oil, propeller or integral steering cylinder. Weights based on Owner’s Manual specifications.
Which is quieter Mercury 115hp or competitive 115hp?
Quieter Than the Competition. The Mercury 115 FourStroke is quieter than a competitive 115hp four-stroke across the rpm band. At idle, the Mercury is four decibels quieter than the competition – the competitive outboard is 25% louder. At cruising speed, where normal conversations occur, the competitive outboard generates almost 15% more noise.

What is the rating on a boat battery?
The marine cranking amp (MCA), or just cranking amp (CA), rating found on a battery’s label measures a battery’s starting power. And if you’re using a newer model outboard with sophisticated computers, pumps and sensors that don’t take kindly to being underpowered, you certainly don’t want to scrimp on starting power.
How many horsepower does a marine outboard motor have?
