Try This If Your Motor Isn’t Peeing

Use this when your motor isn’t peeing. It’s small, it’s free & might save your fishing trip.

Not taking the marsh seriously and failing to prepare can lead to disaster for an inshore angler. Don’t be naive!

We want to have fun when we go fishing, and that is virtually guaranteed when we are prepared. So here is what to do when your motor isn’t peeing.

Outboard Motor Isn’t Peeing

First off, what do I mean by “peeing”?

Most outboard motors are equipped with a cooling system using outside water.

Outside water is circulated through cooling passages before leaving through the motor’s “pee hole”.

You’ve seen it! It looks like the motor is taking a whizz everywhere it goes.

This way the motor stays cool and doesn’t over heat. But if it were to stop peeing…

Why is it dangerous when a motor isn’t peeing?

An outboard could overheat and cease to function, leaving you stranded with no way on.

Do you want to be stuck drifting across Breton Sound? Nope!

How can we fix a motor that won’t pee?

Two things:

  1. clear the water intake
  2. clear the pee hole

Clearing the water intake is easy: trim up the motor, inspect the intake and remove any debris fouling its operation.

Running through thick grass can clog the water intake.

This clog is easily wiped away with your hand.

Sometimes that’s all it takes to get the motor peeing again. However, if that doesn’t do it, then you need to clear the pee hole.

This is a dead giveaway when your motor isn’t peeing.

Clearing the pee hole isn’t easily done with your fingers. You need one (or both) of these tools:

  • thumb tack
  • stripped twist tie

Use the thumb tack to clear clogs at the pee hole and twist tie (with the coating stripped off) to clear clogs further upstream.

As long as you maintain your outboard and have these items on hand you will always be able to clear clogs when your motor isn’t peeing.

    A piece of weed eater line works well also
