i searched and found that it says its a visco damper... is that like a fluid damper? if not what exactly is it and is it better than a stock damper?
 
not all marine dampers are viscus, i have 2 sitting on the shelf that are solid, they are smaller and look a lot differnt than the truck dampners. i would imigan any viscus dampner would be better on a solid
 
yea i did some more searching out side of the site and found that. thanks. i found one for a marine 5.9 and was wondering. i thought thats what it meant but wanted to make sure.
 
so is a marine damper just as good as a fluidampr or ati damper? here is the Cummins part no. 3918999

The following is Cummins' description of the part.

173.76

2649
Damper Type: Rubber
Pulley Type: Cast 8 Groove
Front PTO Provision: No

One thing about the fluidampr is that it has an SFI rating on it.
 
I have 12V Cummins marine Visco damper, there is small problem: no tach signal holes .

Stock dampers fail rather quickly with high rpm...vibrations + rubber = heat, heat = rubber failure LOL
