Engines / LPW 3
« on: April 25, 2019, 11:02:39 PM »
Hi all,
I bought an LPW3 a few years back to replace an aging (and underpowered) SW2.  Only just now getting around to it! It's going into an 8 tonne auxiliary yacht here in NZ. Belt drive variable pitch prop, so no gearbox issues...
I'm in the process of bench testing the engine, and discovered that it appears the engine is governed to about 1500 rpm. The engine has never been run before, and it came from a generator supplier who'd over-stocked on engine replacements. I got lucky.
My question is:
Can I, or should I, replace the governed system with a throttle controlled system? Is it better for the engine to run at a constant revolution? I can vary the prop pitch at will, so no issues with power output.
