[PCW] Diesel load and related questions

[Mark]

A few links on variable pitch props...first one has a cost comparison from a few years ago.

Subject: [PCW] Diesel load and related questions

Something you always read about is diesel load, too little is bad too 
much is bad. How do you know what your load is at any given time? Is 
there a diesel load meter or gauge ?

Next since once you have a engine and transmission the only variable 
related to load is the prop. IF  that is the case would this not be 
the reason for a variable pitch prop setup?

If you had a variable pitch prop would it make a difference on the 
engine load? and would it be worth the cost. ?

If you had a load gauge could you set the prop pitch to the best load 
for your situation, and would this relate to fuel economy?

Am I way off base here or is this something that should be seriously 
considered when buying a boat or retrofitting a boat.

Hope this is not a dumb question
