Exhausting thru the hull or I should get it thru the prop.
Question:
Buck, I agree with everything you wrote below. That cig boat was built for offshore racing, and it definitely has its place. And in an offshore race, with the crew wearing earplugs, open them baffles up and let er roar. Its funny though that the guy thought his rig was fast enough to want to race us. Just like I’d never even think about trying to race that drag boat. My point was that you can get performance without making a lot of noise and bothering a bunch of people. And I didn’t take it as a flame. Don W. – Hide quoted text — Show quoted text – Don, I think the speed of your boat virsus the Cig just goes w/o saying. Look at the horsepower to weight ratio. Kinda like the Ranger and Bullet bass boat all the rednecks run in my area. Big outboard engines, and probably the fastest boats on the lake. I have yet to see one pass me in 4′-5′ water though. That Cig would walk away from you in the big stuff. My point, different boats making speed in different conditions. Put that Cig on Lake of the Ozarks on a holiday weekend next to you and my money is on the Cig. A Porsche will smoke a lifted jeep on a curvy road. Put the jeep on a pig trail and the Posche doesn’t stand a chance. Not intended to be a flame. Buck #183
Response:
Dave, Agreed. And if you are racing, that 2-5MPH is golden. If you are running a pleasure boat it may not be as important as keeping the peace with your neighbors on the lake. Basically I agree with what you said below. Don W. – Hide quoted text — Show quoted text – Dave, You’ll get a lot more "performance" from a supercharger or turbocharger boosting your intake manifold pressure to ~10PSI above ambient than you’ll ever get from running open headers and a funky cam. Ah, but you’ll get even MORE performance iff you add tuned headers and thru-transoms on top of that blower. Any wrench-head worth his salt knows that the secret to maximizing performance is allowing the engine to breath. The more fuel/air that you pack into a cylinder, the more power it produces. Part of that formula is getting the exhaust out of the cylinder quickly so to make more room for a fresh fuel/air charge. It doesn’t do you much good to put all that "stuff" on the intake, if you can’t get the spent charge out to make room for the new charge. Also, not everyone has the kind of money to build up a full race motor (and they’re usually not very reliable for recreational useage). However, "stage 1" modifications (Intake, cam and exhaust) can net anywhere from 30 to 70 more horsepower from a big block engine. That can translate to a 2 to 5 MPH increase in speed. That may not sound like much, but it can make the difference between winning and losing. We were out testing props on the tunnel boat one day and a guy with a cig. boat running _3_ v8 powered stern drives came around and wanted to race. He looped around us a couple of times while we were changing props and then put the pedal down to show us what he could do. We put the radar gun on him and laughed. He was doing about 75 to 80 mph flat out. Our SST 120 tunnel boat did around 109 mph with a stock Mercury outboard power head, and racing lower unit. If we had raced him we would have had around a 30 mph edge. Come to think of it maybe we should have convinced him to race title for title… I wonder who would’ve won that race, if there was a 3 foot chop running? Again, anyone into performance knows that speed is a function of power vs. weight. My 17′ Hydrostream YT tunnel, would bump the 80 MPH mark with a stock Merc 175. My current 24" Checkmate is lucky to hit 70 MPH with a 425 HP 502. But I (and more importantly, my wife) would get stomach pains after hitting even small chop with the Hydrostream, but the Checkmate slices right through all but heavy cruiser wakes, with nary a bump. It all depends on your application. Oh yeah… and his boat made a _LOT_ of noise too… My point is that loud is loud, and fast is fast. The two are not necessarily equivalent. No, but the same boat, with the same engine, will jump from 1 to 3 MPH when you flip the switch on the Captain’s call and go from thru-prop, to thru-transom. But I agree that having a loud boat comes with a certain set of responsibilities. You have to be aware of the impact that your boat will have on others. If you don’t have a means (Captain’s call) to silence the engine(s), then you should respect others and NOT run the engine(s) at "quiet times". Dave

CP Performance has several styles of silencers/mufflers, http://www.cpperformance.com/products/exhaust.htm I’ve always loved the sound of open exhaust on a boat, provided that it is not a 2am. As a kid I remember being at my Grandfathers lake house and hearing the inboard ChrisCrafts in the 60’s and the big block Jet Boats in the 70’s. I have my own lake house now and still love to hear the boats, it’s just a sound that I associate pleasurably with lakes and boating. I would much rather hear a healthy big block exhaust than my neighbors lawn mower/weed wacker/leaf blower, etc.

Response:
Many of the creeks around here have community groups that have successfully enacted noise restrictions. doug – Hide quoted text — Show quoted text – I highly recommend thru the prop. It is quieter, and you don’t get the exhaust gas blowing back over the boat in a following wind when your idling. As for performance, my stock Maxum 21′ goes 55mph–quietly. I’ve often toyed with the thought of adding a supercharger to my single mercruiser V8, upping the prop pitch, adding planing trim tabs, and giving the next loud multi-engined $100K+ cig. boat that tries to blow by me a BIG surprise. 
Someone else said "If its too loud, you’re too old." That kind of thinking got a noise limit law passed here a couple of years ago, and now the water cops can write tickets to any boat that exceeds a certain dB from a certain distance. They can also pull you over, haul you in and measure the noise. (Lake Travis, Austin, TX). The people who live on the waterfront finally got fed up enough to put together a lobbying group that got the new rules passed. Its probably only a matter of time before other locales do the same. Good luck, Don W. My new boat has the option of exhausting thru the hull or I can get it thru the prop. The Mfg is asking which I prefer. My Merc engine choice comes std with thru the hull but I can opt out. I am thinking of opting out because I don’t care about the slight performance increase and prefer a quieter ride, but I don’t know if there is any compelling reason why thru the hull is better Please give me your advise as I am not familiar with the pro and cons of the choices.

A few years ago Mercury had an option called "silent choice" I believe. It offers you the option of prop or thru transom and is controlled from the helm. I think it was a $1,500 or so option that may or may not still be available. Good luck.

My Merc engine choice comes std with thru the hull but I can opt out. I am thinking of opting out because I don’t care about the slight performance increase and prefer a quieter ride, but I don’t know if there is any compelling reason why thru the hull is better Please give me your advise as I am not familiar with the pro and cons of the choices.

Up to you. You can get some performance with proper Propeller tuning and weight distribution. Noise is a lot more, for you, and for everyone else anywhere near — for that matter, weather permitting, you can hear those a-holes miles away, but that’s just my opinion. The really sinfull thing about through-hull exhausts is when your generator goes straight thru, sideways, pointing at me, trying to sleep, at the dock or anchorage. That’s when I really ~yearn~ to share feelings with fellow, thru-hull users.

- Hide quoted text — Show quoted text – Thru-hull continues to mystify me. It seems to me a testosterone thing. I’m not against testosterone – I just think we should harness all that energy and control it, not have it control us. Thru-hulls, depending on where you’ll be using them and what you’ll be doing with them, are simply unsociable, IMHO. It’s a very clear way of saying, "I have my rights – but you don’t have yours."

I agree. The only reason to have through-hulls on a testosterone boat is to make sure everyone else knows you are around. The noise really is obnoxious. — Harry Krause – - If you don’t come in on Sunday, you needn’t come in on Monday. – Management sign threatening garment workers at Triangle Shirtwaist Factory, 1901.
