clunk

[zookeeper]

hi there folks, when putting boat into gear it "clunks" only a bit but just enough to be annoying, how to i adjust it?

What outboard is it?

I thought they all clunked (within reason). A bit like motorcycle engines which do the same from neutral to first.

Some outboards are worse than others. My Yamaha was as smooth as you like, then I had a Merc 4 stroke which clunked quite loudly. I was told that this was quite common on this make and model of engine from the dealers I had it serviced at. My Evinrude it quite smooth too, but does clunk a little going into reverse but that is compared to going into forward.

I've been told that stainless props and solid hubs can cause a little more clunkiness to gear changes.

Yep, there'll be a throttle stop screw under the cowling somewhere which you'll be able to adjust to get different Idle speeds. Just make sure it's the one that adjusts all the butterfly valves together and not individual ones.

Yeah that will give a big clunk if its too high
