Stainless Steel 4 Blade Impellers : Wooldridge boats has come up with a improved thinner stainless steel 4 blade impeller that increases efficiency. HOWEVER this is usually not a viable situation for motors below 120 hp when installed on heavier boats as the impeller is now so efficient that the se lower powered motors now are underpowered and you may even loose performance over the original impeller.

Boy did I get enlightened, that was not the prescribed method. And not many old wooden cattle watering troughs still exist today. [links]
Tap this hole in the jet housing to 3/8" X 16 NC threads.
If that does not do it, you might have to resort to a Oxy-Acetylene torch to heat the impeller. In doing so you will ruin the nylon busing that is between the impeller and the drive shaft. But at this point, it is sacrificial and inexpensive. When purchasing a new bushing, you will need to know what size your jet unit is. On the RH side there will be (on the newer models anyway) a small aluminum plate held on by 2 nuts. Here will be the model in alphabetical letters and the serial number. The letter, or even 2 is what you need, like A, F, L or S etc. If your unit is an older on without the model number affixed, then you will need to measure the shaft size at the impeller.

As we stated earlier, flushing the cooling system consists of supplying
fresh, clean water to the system in order to clean deposits from the internal
passaqes. If the engine is running, the water does not normally have to be
pressurized, as it icdelivered through the normal water intake.passages and
the water Dumr, (the svstem can self flush if sumlied with clean water).
Smaller, portable engihes can be flushed by mounted them in a test tank (a
sturdy, metallic 30 gallon drum or garbage pail filled with clean water).
Almost all mercury engines will also accept flush fittings or
adapters. Most adapters are of the generic type and are designed to fit over
the engine water intakes on the gearcase (and resemble a pair of strange
earmuffs with a hose fitting on one side). But, other adapters (available from
the manufacturer) are designed for special flushing fittings on specific
motors. These special adapters attach to a cooling passage on the gearcase
or powerhead. When using the later type adapter, follow the manufacturer's
instructions closely regarding flushing conditions. In some cases, flushing
with this type of adapter should occur only with the motor turned off, so as to
prevent damage to the water pump impeller or other engine components.
This varies with each motor, so be sure to check with your dealer regarding
these direct to the powerhead adapters when you purchase one.
W Most jet drive models are equipped with a flushing port mounted
under a flat head screw directly above the jet drive bearing grease
fitting. Use an OMC adapter (#435299) or equivalent to attach a garden
hose to this port.
When running the engine on a flushing adapter using a garden
hose, make sure the hose delivers 20-40 psi (140-300 kPa) of pressure.
Some of the smaller, portable motors covered by this manual utilize a
water intake that is directly above the propeller. On these models the
propeller must usually be removed before a clamp style flush adapter can be
connected to the motor (unless the adapter is very thin and mounted so
close to the anti-ventilation plate that it will not be hit by the propeller).
For safety, the propeller should be removed ANYTIME the motor is run
on the trailer or on an engine stand. We realize that this is not always
practical when flushing the engine on the trailer, but cannot emphasize
enough how much caution must be exercised to prevent injury to you
or someone else. Either take the time to remove the propeller or take
the time to make sure no-one or nothing comes close enough to it to
become injured. Serious personal injury or death could result from
contact with the spinning propeller.
When using a flushing device and a pressurized water source, most
motors can be flushed tilted or in a vertical position, BUT, the manufacturer
warns against flushing most motors in the tilted position with the engine
running. Some models (especially most 4-strokes) can be seriously damaged
by attempting to flush them with the engine running in the full tilt position. If
the motor must be flushed tilted (dockside) then your best bet it to do so with
the engine shut off.
1. Check the engine top case and, if necessary remove it to check the
powerhead, to ensure it is cooled enough to flush without causing thermal
shock.
2. Prepare the engine for flushing depending on the method you are
using as follows:
a. If using a test tank, make sure the tank is made of sturdy material,
then securelv mount the motor to the tank. If necessarv. oosition a wooden
plank between the tank and engine clamp bracket for
(above the water inlet).
b. If using a flushing adapter of either the generic clamp-type or
specific port-type for your model attach the water hose to the flush test
adapter and connect the adapter to the motor following the instructions that
came with the adapter. If the motor is to be run (for flushing or testing),

Anyway, as noted, not obvious.
Thanks Tony. I had downloaded the manual, even been to a dealer, with a service manager who couldn't point it out.. Ya I won't be buying, or bringing work there..
The intake is on the bottom side of the cavitation plate. There's nothing to hook an adapter to, just a strainer about the size of your thumb nail. Start the motor and hold a garden hose up against the strainer, and the motor will instantly pick up the water it needs. It only takes a few seconds to flush out the salt water. more
