No
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.
You would use a worm drive meshed with a gear that has 130 teeth.
No. With the values given the motor will run at 1500 RPM. RPM = Hz x 60 x 2/# of poles. The only way the motor can be run at that speed is by using a VFD as its source of power.
my manual says 4200rpm to 4600rpm at full throttle
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.
Materials for producing 2900 rpm motor is less than 1450 rpm one
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

Relationship between motor rpm and no of poles
260 hp @ 5000 rpm 330 tq @ 2400 rpm

I believe redline is 5,000 RPM.
260 HP @ 5,250 rpm; 302 ft lb torque @ 4,000 rpm
260 hp @4600 rpm and 380 ft-lbs @2700 rpm
No. The water pump is designed for a specific RPM. It will not operate correctly, and will probably be damaged, if you attempt to operate it at twice the design RPM.
