Here are 3 that are pretty close.
1. can a gear be rebuilt from one ratio to another?
2. Can a gear get pulled out of an engine room without removing the engine?
3. What si the rough cost of a new ZF/311 1.75 gear ratio and what is the rough price of a quality rebuild?
Background is that I am finding my boat/engine/gear/prop is not giving me what I want when fully loaded or in moderate sea conditions.
On one end the God of Cummins says "reduce pitch to decrease load" and on the other end the God of Props says "all that do will slow you down - your not getting what the engine can give w. your current 1.5 gear ratio"
This is a winter project (if at all) and I am invetigating my alternatives"
NB 36/ QSM 670/IRM10 w/ a 1.5:1 ratio, DQX 26 X 26 prop. I was hitting WOT correctly in perfect conditions, lightly loaded with a fresh bottom, off by 60-80 RPM now...
