Received the wrong type of kavan muffler adapter?

Postby novaris » Tue Jan 08, 2013 3:51 am

Recently I bought a set of kavan muffler and adapter (no.4) for my merco .61 mk2. I am pretty sure it is a mk2 as it is a twin plug version as described here (

However, the included adapter doesn't fit the engine exhaust port nicely, it does fit the kavan muffler nicely though.

The adapter you have is for the earlier MERCO MKII. Merco added the 2 screw bosses later in the production. We do not have one but you can easily file or Dremel the ridge on the adapter to clear the bosses. It will still locate fine. Just remove enough ridge to clear the bosses.

BTW if you look closely at the picture in the link you supplied you will sen the engine does not have the bosses like yours and it is fitted with an exhaust baffle.
