Water lubricated stern gland

[richardabeattie]

My new stern gland has a hose feeding water to it - no more remembering to turn the greaser. The water comes from a T junction cut into the hose going to the elbow. So my question whether the reduction in the amount of water going to the elbow will increase the exhaust temperature significantly. (Raw water cooled 2GM20).

I have a similar arrangement that feeds a small dose of water to the stern seal. I doubt it'll have any effect, unless you run the engine at full rev for a prolonged time. My engine is a Nanni 2.14.

Ditto me. I have a Volvo 2030B for 24 years with that arrangement and before that with a BMC 1.5. It does not interfere at all. The water feed also supplies the outer bearing; no stagnant water harming the shaft.
