    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 in the “Tony’s Tips” section, there’s plenty of photos of various solutions.
