Yamaha OEM: Bali vs. Hawaii

Mike showed me a good place in Bali to buy parts for my motors.  It’s a marine shop near Denpasar.

It’s a very local shop that has lots of toys.

I needed a lot of different parts and seals for 2 motors.  There is only one place in Hawaii that sells it so it’s like a monopoly.  It’s so expensive!   Anyway, I check the prices before I went to Bali and found out that it much cheaper over there.  Everything was 1/3 the price so I saved a lot of money.

I’m taking my time because I want everything right.  I’m still learning and am very excited for everything.

So here’s a lower unit I just pulled off one of the motors.  In that white cap, there is an impeller and a water pump.  If either fails, your engine will break and cost thousands to fix.  Or worst, you will be stuck in the middle of the ocean.

Changing the impeller and water pump should be done every 300 hours on the motor or every 1 to 3 years, which ever comes first.  3 years came first to it was time.

My brother changed it for me the past 2 times but this time I wanted to do it alone.  The more I’m involved with the motors, the more I will understand it.  After my boat breaking 5 hours away from Oahu last time, I learned that I should know everything and anything about my motors.

A cheap fix if you do it by yourself.  A very expensive fix if you hire a mechanic.  I just did both motors so it’s become very easy to do.  I also learned how the water flows through the motor and cools the system.  Whatever has to do with FLOW, I want to know…

Good morning 4:40am.
Ala Moana head high and bumpy.
Diamond Head overhead and bumpy.
Southeast winds at 15mph.
Clouds, rain, and warm.
Going to the sea.
Have a wonderful day!

The morning conditions everywhere were really ugly so we decided to wait.  I felt the wind change at noon so I went to look at Diamond Head.  It was getting better and better by the minute.  

Two hours later, we were out at Diamond Head.  It was a little big and wild but that’s what we like.  

Hashimoto-san caught 4 good waves and was surprised with the power of the ocean.  The water was moving a lot and felt really thick.  All I saw was his take offs and the wave exploding well over his head.    

Our last wave we rode together.  It was an amazing experience and now I think we have another surfer who loves Diamond Head.  

No matter who you are or what condition you are in, you will be very tired walking up this mountain after a surf.  I’ve been doing it for 40 years and it’s never easy.  

A big project happening now.  I’m going to spend the next couple of weeks making sure everything is perfect.    

First is taking things apart and replacing all the seals.  Then on to the paint.

I’m learning so many new things about how these Yamaha motors are built and operate.  It’s pretty simple when you break it down.  I’m having fun taking things apart and putting it back together.  And I’m having fun saving thousands and thousands of dollars doing it by myself.
