I have a 2010 C DORY 19 ANGLER. Yamaha 90 It is very noisy at the HELM at SPEED Not bad at all in cockpit. Has anyone come up with a cure to lessen the noise. Some sort of a barrier board in engine well???? DOUG DANIELE EASY STREET!!!!! dougbiking@ hotmail.com
 
Close the door? Wait! That may be the problem...no door. Actually the problem may be that the sound is being focused by an open cabin. Sort of like cupping your hand around your ear to hear better.

Besides ear plugs or an iPod several people have created seats in the well that might help cut down the sound. I suppose big cooler on a rack would also help some. I did see a picture of a fully enclosed structure build around the well but don't remember which album. I like the seat on Tortuga but I don't know if it helps with the sound at all.
 
My old boat was really loud in the drivers seat. I realized a good amount of the noise was engine and hull vibration being transferred up the throttle cables and vibrating behind the wheel. I padded the cable better along the hull and it reduced noise up there quite a bit.
 
The lack of back door makes the cabin like an echo chamber, and my 19 was pretty noisy. I took to using earplugs right away and then brought my aviation headset along pretty big difference. Engine trim and rpm will produce resonance also try moving power settings and trim angle to get an improvement. My 22 is a bunch quieter but at higher speeds and longer runs I'm using the earplugs and headset now also. I'm hearing challenged so want to preserve.

My 19 was also pretty annoying at certain RPM's. Chatting with other 19 owners, the problem varied significantly between different outboards. At the time I owned it (several years back), it seemed like Yamahas were the worst by a large margin (mine was an F80) Hondas were better, and the Suzukis the least annoying.

On mine, it wasn't so much the noise, but the resonance and harmonics. Certain RPM's would send a buzz through the air/hull, that was far more annoying than simply excess decibels.

If this description matches what you are encountering, there were three things I did that made a world of difference on my 19. A four blade prop, trim tabs, and a Permatrim.

The four blade prop performs much more smoothly than three, and was likely responsible for the largest reduction in noise. The Permatrim and trim tabs, allow you to fine tune things such that the engine RPM's are in a less annoying range for a given speed. This is particularly helpful at lower speeds, as the 19 typically requires you to throttle up to much higher RPM's/speed to get on plane, than a 22. It's these higher RPM's that were the worst on mine.

Even with the reduction in noise these items provided, I ain't gonna lie...much as I liked the open access to the cockpit and the fishability of the 19, I hated it every time I throttled up. The 22 is soooooo much quieter.
