If you have a Mercury Optimax, and probably a lot of other outboards, near the top where the "pee" stream comes out there is a Plug.
Unscrew that plug and screw into where it was a garden water hose.
What this does is run water Backwards through the entire system flushing out any bits and pieces that get stuck in there causing low water flow.
I turned the water on into mine and I could hear the water working it's way through.
The stream went from this:

To this:

It also cleaned out the lower pickup ports so that the water flowed strong through them.

Just a quick and easy way to clean out your motor. Especially important if you fish in grassy or sandy/dirty water.

Good reminder with pictures Fred!!!

There is a chance I get my new repower 150 today. I normally read the manual but I will see if Tohatsu/Honda has that option.
Good tip!

I too have an Optimax with a weak pee stream compared to others.
How are you attaching the water hose to the motor, I just can't see in the photos?
@BK
There is a screw cap you remove to connect the hose.
Also if you take your left lower housing of there is a water filter that is not replaced during a normal Mercury service. Its a pain to get to but the time spent is worth it.

Thanks FD, I'll check it out next weekend when I get over to the boat.

Right beside the Pee Hole is a plastic plug. I use a crescent wrench to remove and replace mine. It has a Square Head on it.
FD is correct there is another water filter (a screen) that is located on the left side of the motor facing forward.
A zip tie holds the hose on, then once the hose is removed the part that holds the screen screws off.
As to how I screw the hose on to back flush, I reverse twist the hose several times then put it on the opening. That helps to allow you to twist the hose on.
