Outboard failure!

The part that caused all the problem

The part that caused all the problem

We have been loving our Tohatsu 9.8 outboard.  Reliable, light, quiet and lots of get up and go, BUT like all things mechanical  they all require a little fixing from time to time.  The latest repair saga begins with the Tohatsu making oil – gas was somehow getting into the crank case.  A quick canvas of the anchorage resulted in us suspecting a carb problem.  I changed the oil and cleaned the carb seeing nothing really wrong.  One week later I was faced with the same problem again, sigh.  Lucky for us we were anchored in Melaque where my sister (Laurie) and partner (Rob) have a winter home.  We moved the outboard to Rob’s shop called the local outboard guru and learned a lot about these engines in quick order.  If you have a carb problem that is leaking fuel it will show up in the water coming out the exhaust by the prop.  I our case, making oil is the result of a failing fuel pump diaphragm.  Finding the problem was easy but getting a part in Mexico turned out to be quite a process.  This part can be bought in the USA for $15.00 but from Puerto Vallarta (the closest source of the part) it would cost $90.00.  On top of that it took a week to get here, first being sent to the wrong part of Mexico….!  With part here the Tohatsu is once again happy.  The big take away is make sure you have a spare fuel pump diaphragm!
