    Hey all,

    I have been tinkering with ideas on how to design a new exhaust riser to inject water at a later stage which will in turn prevent the chance of water backing up into the turbo/engine when sailing.

    I've cut up some PVC and started to play around with different designs and such to see what would work best, but what i'm having a hard time with is - how do i support the long runs of dry the dry exhaust to prevent leverage on the bolts holding in place on the turbo?

    As for heat - how well do the custom exhaust blankets work? Will it be cool enough that say a raw water hose can touch without harm?

    You may need to insert a flex coupling off the turbo outlet, and then support the Exhaust riser off the boats structure.
    Look up sbmar.com in the “Tony’s Tips” section, there’s plenty of photos of various solutions.
