Hello All,

I am rebuilding the exhaust on a Grampian 30.
I intend to use the Vetus L40 water lock and matching 40mm Vetus hose.
My plan is to use black iron to create a riser at back of manifold,
up +- 8", then turn back down towards water lock using raw water mixing fitting and nipple. From here 40mm hose to H2O lock and then to stern.
I plan to put a rise in the hose before the exit point in the stern as it is quite low.
I appreciate any input regarding design.

Thanks,

Joe
