Z175TXRZ motor ????

[Mike2043]

Hello everyone. I have been lurking here for a while and now I have a question for you folks.

I have a 2001 Yamaha Z175TXRZ motor on my boat. I have the owners manual and I used that to order some parts ( spar Plugs ). Now the manual say for motor Z175TRZ it does not list Z175TXRZ does this X mean anything?

The manual calls for BKG BRKR7ES so that's what I got. Now when I cahnged them I found that BKR7EKU were in the motor. They are an spitfire type plug..

Do I have the right plugs in the motor?

Thanks in advance.....

The "X" stands for 25 inch shaft length. There was a change in plugs so you have to check serial number of your motor,
serial number between 800101-800231 use BKR7ES-10 plugs
serial 800232 and above use BKR7EK-U1 plugs
