1. Throttle: Check that the throttle is opening fully.
2. Fuel: The fuel supply must be adequate for the engine size. Racing boats frequently have a fuel pressure gauge which is,
with the tachometer, probably the most important engine instrument. Sufficient fuel must be reaching the engine.
3. Air to the engine: The carburetor must be getting its full quota of cool air. If the engine has to work to get adequate air, and if
it is hot air, this will reduce power.
4. Ignition spark: Be satisfied the ignition system is operating properly. A problem here is usually indicated by a rough running
or missing engine.
5. Exhaust: Check for a free flowing exhaust system. Some silencers can become blocked, rubber hoses disintegrate internally,
or there is excessive water injection. Such things can cause excessive back pressure and reduce power.
Provided your engine is getting its full quota of air and fuel, and is getting enough spark and at the right time, the engine
will usually be OK, and maximum RPM's will result. However if the RPM's are down and you believe the tachometer, look
for an engine problem. The hull, engine, and jet unit are the three main areas to look at when your performance is down.
D. Excessive noise.
This can often be a concern even if there is not a reduction in performance. The most common causes of noise are:
1. Cavitation: The jet unit is starved for water, and usually sounds like a rattle or a can of loose bolts in the back of the boat.
Most likely a blocked intake grate.
2. Moan or whine: The jet unit can exhibit some "turbine whine" not unlike a turbocharger noise but you will know what is usual
with your boat. However, if you have a new more obvious moan/whine, especially if it is a very low frequency grumble at idle,
that increases with engine RPM's then it is likely to be a rough/worn/water damaged thrust bearing. If water has gotten into the
bearing, it is usually as a result of a flooded bilge at some time on a warm bearing, then water can be sucked in as it cools.
3. Periodic vibration: Often at specific RPM's and disappearing at other throttle openings is probably a torsional vibration emanating
most likely from the universal joints on the drive shaft.
