How loud is loud with an A4? (  jaschrumpf 06-11-2007 02:55 PM
How loud is loud with an A4? I am completely new to A4s -- or
inboard boat engines of any type, though I am comfortable
working on gas engines -- and I read that the A4s run smooth,
quiet, etc., and I wonder just how smooth and quiet they should
be.  Mine is in a 75 Newport 28, and was rebuilt by Moyer for a
PO back in '93. It starts up and runs fine (though I suspect the
carb is set a bit lean, but that's another thread), but it's not
like you can't tell the engine is running at 1000 rpm.
Everything in the exhaust system seems to be working OK, water
pumps out the exhaust in regular bursts, just a little blue
smoke at startup and then it goes right away. I can't really say
anything is wrong with the "muffler", I just have no A4
experience to compare my engine with.  What would you say is a
"quiet" A4? Barely hear it inside the cabin at 1000 rpm? Easy to
talk over? Have to raise your v
