    80A fuse? HPDI 150 help needed.

    2001 HPDI 150
    LZ150TXRZ

    There are 2 fuses in the fuse panel on the motor. This is the fuse from the starter side. It is labeled 80A 32V. On a parts search it shows 60A 12V. What is the deal with this? Where can I get this 80A fuse? No, the fuse has never been replaced. I have twin engines and they are both 80A, as well as the spares that are in the fuse box top.

    Like so much Yamaha data, the parts catalog and the service manuals are screwed up.

    Here is the part number for the 80 amp fuse.

    61A-82151-00-00 YAMAHA FUSE (12V-80A)

      somewhere there is a tech bulliten the 80A fuse with the 60A.
      that's why the parts lookup kicks it to the 60.
      what did you do to blow an 80 amp fuse ?????

        I thought it was a requirement of passing the Master Mechanic test that all technical bulletins back to 1984 had to be committed to memory?

        I guess that it would have taken Yamaha too much ink to put a note in the parts catalog that shows replacement of the 80 amp fuse with the 60 amp fuse?

        Interesting to note that other models still have a call out for the 80 amp fuse:
        61A-82151-00-00 YAMAHA FUSE (12V-80A)

        and the 100 amp fuse:
        6CE-82151-00-00 FUSE (100A

          why they replaced the 80 amp with the 60 amp via the tech bulliten? maybe someones brother in law sells 60 amp fuses.

          it still takes a lot to blow a 60 amp fuse.
          you can weld with 60 amps.

            I take full responsibility for blowing the fuse. Late night, very dark, worked on the boat all day and wanted to test fire it. mixed up a hot and ground on one of the batteries and.... well thats how it went.

            So what you are telling me is that I can replace all of my 80A's with 60A's?

              I found it. Wasn't a technical bulletin but a sorta similar document that Yam refers to as a technical exchange. Yam has a number of different means to get information to mechanics in the field. If they are reading/listening that is. Rodbolt appears to be one of the few that pays attention.

              Here it be FYI

                Yamaha ought to send Boscoe and Rodbolt a check every month for the work they do on this forum.

                  and this my friend is a TECH BULLITEN.
                  its NOT sent to the consumer.
                  it is AVALIBLE to ALL so called techs.
                  its up to the tech to READ and REMEMBER.
                  its also why some parts programs kick the original number to the superceded number.
                  I do try to read all tech bullitens published.
                  I don't like the new stupid format.
                  I like the old marine tech guide format.
                  I really really don't care who is fishing.


                  I kinda figured it was a customer/tech induced failure.
                  happens.

                    Onboard sucks. A step back IMO. With new technical management at Yam I suspect that things might change again. Who knows.

                    The bitch is having read information in the past about a particular issue and then having a hellava time finding it, when needed. Drives me crazy.

                    Some stuff from 1984 is still needed from time to time, but fortunately only once in a great while. Pity the poor new mechanics who don't even know what is available to them.

                      luckily I have MTG's that go back to the 90's. I also have several tune up spec guides going back to the 84 era.
                      onboard is stupid.
                      format sucks and there are to many books.
                      I like the old MTG and the single pages they sent out.
                      they fit in my clip ring note books with a year and bulliten index.
