Both engines have been completely overhauled last spring and have
apprx. 450 hours on them.. Boat performs well while underload at 1950
rpm it cruises at 20-21 knotts. At 2350 rpm boat can run 24-25
knotts. No load engines run rpm up to 2650

First off, I'm neither a mechanic or a diesel expert, but I have some
questions.
1. What's "no load" rpm's "supposed" to be?
2. What is WOT "loaded"?
3. If you try to open a hatch/door to ER when at WOT underway, do you
have to open against a suction?
