I haven't either US1 - I just put them back together using my internal torque wrench - common sense. I'm a saltwater boater and have never had an issue getting them off every other year (no I don't change every year. I only put about 30 hours a year on the last few years so I don't change EVERY year.

Never used antisieze or a torque wrench on a seawater pump myself.
The pump housing is sealed with an o-ring. As soon as the housing contacts the main body, it won't seal any better by tightening the housing down more. The o-ring has already compressed as much as it will.

used to change impeller with hanging on engine. i take pump off engine now. can inspect seals and other parts, use either grease or antiseize on surfaces and bolts. easier to reassemble. no twisting of pump housing when mounting to bracket, can pull bolts tight evenly. that prevents breaking new plastic pump housing, put light coat of grease on impeller to prevent burnup on initial startup.
