Smile Rise in dry stack works for me

Pater et al.,

On my 75' Tartan 27, I have a dry stack rising up about 12 inches above the water line before the water is injected, and flows downward to the water lift muffler, and then a steady 6" rise for the 6' run out. I have an exhaust check valve just before the outlet in the transom.

I do have to snake the dry exhaust forward about 6 inches from the manifold outlet to get the vertical space for the dry stack to go up though, and it is well taped with insulation. I do have 5-second access to the cooling water intake valve on balky startups.

I have encountered no problem in 5 years, with some heavy weather, but am looking to add a few more inches in the dry stack rise just in case--because I can.

Mary
