Do all two strokes.....

[reelapeelin]

Like Willy said...those Mercs have a cam-shaft as big as your leg!!...at idle they all sound like they're waiting on the green light to come down!!...

you would probably have to get a DI 2 stroke (with the opti as an exception) for it not to sound like a top fuel dragster. You should hear a merc race 2.5 outboard engine. That thing sounds wicked. Its hard to describe.

Like above posters stated, normal. It's just the nature of a 2 stroker and the way they breath. Also the lack of oil in the bearings adds to it alot. Remember that a 2 stroker simply oils the bearings by the residual oil in the crankcase that comes out of the fuel whereas a car engine has oil pressure in between the bearings and the crankshaft. 2 stroke engines bearings are designed to last, but not neccesarily to be quiet doing it. My old 81 150 MERC sounds like a top fueler with a mis-fire when it idles.

My father in law has a 112 Johnson and it sounds like a sewing machine at idle.

its probably full of carbon and the carbon is insulating the sounds, j/k its a crossflow joke

[Karl_Childers]

So are crossflow's a little quieter/smoother than loopers?

i dont find they are. but the long running joke is that the crossflow v-4's carbon up real easy and at times break the rings.

Yeah they are loud on the hose. And rough running at idle. I dont think it gets much better. Thats how the neighbors know your home from fishing.

hey if you like the way a harley sounds youll love the sound of a merc.
if it sounds bad then its running good
