This speaker is 16 ohm and 2 watt and is about 2" across (50 mm). It is a good replacement for any of the 16 ohm speakers. The amp on those boards cannot really handle more than 2 watts cleanly anyway--so if you are trying to replace a 5 watt speaker, it will work fine. We use them, and the engines sound great. DO NOT use unless you are replacing a 16 OHM speaker. That part DOES matter.
It is a good replacement for parts number BF-0000025,
BF-0000031 and BF-0000033. May fit others.
The speaker is
- 50 mm (2")
- 16 ohms
- 2 watts
You may need to do some minor adjusting as some speakers had a little gasket on them (sometimes you can peel and reuse); other folks simply use washers. Note that this speaker does not have the MTH connector, so you will want to splice or reuse the one you are replacing.
PLEASE know what you are buying and KNOW your application.
