One way or the other

On the switchable exhaust, I can understand why you shouldn't switch beyond a certain rpm. But can you keep them on the quieter setting at any speed, or must you turn them off?


It's a quandry I had when looking at a couple of boats. One dealer said Absolutely Not when I asked him if I could get one with an thru prop exhaust (quiet). I was just asking, not really in a buying mood. I do know that at certain HP, thru hulls are specified.

Having a law against switchables is quite silly, but now I understand that quiet exhaust pipes Can be added after the fact.

Thru hub is not offered on HP engines. (other then the one APS speaks of) all switchable exhaust I have ever researched is designed only for low RPMS. 1. you can't switch at speed 2. you are not supposed to have them on beyond 2000 rpms. Pretty much the best is for idle only. The boats I have been in that have them turn it off upon take off.
