The RPM range for a MerCruiser 260 motor typically spans from 400 to 4,600 RPM. The engine is designed to operate efficiently within this range, with peak horsepower generally achieved around 4,200 to 4,600 RPM. It's important to consult the specific owner's manual or manufacturer specifications for the exact RPM limits for your model.

The cam shaft opens the valves for the inlet of gas/air into the piston chamber & exhaust of used fuel has a smooth rpm operating range. The proper timing of the motor to run idle is usually 600-800 rpm. While the motor is trying to start and gain rpm, the pressure from the compression of fuel lags on all other piston until the smooth idle operating rpm is reached. Making the motor lag on start up.
The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.
Motor RPM (revolutions per minute) can be calculated from frequency in hertz (Hz) using the formula: RPM = Hz × 60. Therefore, for 20 Hz, the calculation would be 20 × 60, resulting in 1200 RPM. This means a motor operating at 20 hertz is rotating at 1200 revolutions per minute.
You would use a worm drive meshed with a gear that has 130 teeth.
my manual says 4200rpm to 4600rpm at full throttle
The maximum RPM for a MerCruiser 260 engine typically ranges between 4400 to 4800 RPM, depending on the specific model and configuration. It's important to consult the engine's manual or specifications for precise limits, as factors like propeller selection and boat load can affect performance. Always ensure the engine operates within its recommended RPM range to maintain optimal performance and longevity.
As stated in the Seloc manual, for a Mercruiser 233 (Ford 351W), the rpm at between 3800-4200. These are the figures for min-max rpm, and they apply for ALL Mercs 233s.
A STANDARD MERCRUISER 2 BBL V6 PUT'S OUT 190 HP. A 4BBL V6 PUT'S OUT 210 HP. A TBI V6 PUT'S OUT 230. AND THE BEST FOR LAST A V6 MERCRUISER EQUIPED WITH THE M.E.F.I. 3,4,AND 5 MULTIPORT INJECTION WILL PUT OUT 260 HP. WITH A LITTLE TWEEKING YOU CAN SQUEEZE MORE OUT OF THAT GREAT LITTLE BLOCK! A MERCRUISER LONG BLOCK MAY BE THE SAME ON THE OUTSIDE AS WHAT YOU WOULD FIND IN A VEHICLE, BUT THE VALVETRAIN IS DIFFERENT IT USES HYDROLIC LIFTERS AND IS MORE OF A HEAVY DUTY SYSTEM. A MERCRUISER IS DEIGNED TO RUN AT 4600 RPM (WOT) ALL DAY! YOUR TRUCK WOULD PUKE IF YOU TRIED DOING THAT. WAZ-2 PRESPHIAMARINE.COM

The Polaris XC 600 motor typically has a maximum RPM of around 8,000 to 8,500 RPM. This range can vary slightly depending on the specific model and year of the snowmobile. It's always best to consult the owner's manual or manufacturer's specifications for precise details relevant to a particular machine.
The Yamaha S150TXRW outboard motor typically has a maximum RPM range of around 5,000 to 6,000 RPM. This range can vary slightly based on specific model year and conditions. It's important to consult the owner's manual or Yamaha specifications for precise details regarding your specific engine.
I believe redline is 5,000 RPM.
