Diesel Generators

I can visually see the electronic speed actuator moving in and out when this is happening. Should I replace the actuator or could it be something else. This is in a boat.

I would first replace the primary and secondary fuel filters. It could have a governor problem in the injector pump. The fuel transfer pump may be bad (not keeping the injector pump body fully charged). The "actuator", actually may be the run/kill solenoid. If so, some have two windings, a "pull in" and a "hold". Check to see if voltage is constant on the hold winding when it is running. Most generators that I have seen and worked on, have a fixed throttle setting on the injector pump.

we have a compressor that is connected to a 3-phase 30hp 230/460volt motor, we want to power it with a diesel generator. Which will be placed approx. 300ft away

The generator will need to produce approximately 23Kw and with a 25% surge factor, you will need approximately a 30Kw generator.
A typical commercial generator with this output has around 100 HP.

I bought an old moving truck that I only want for storage. It will be parked on my off grid property. I would like to rig it to run a generator that could charge up a large bank of batteries for when my solar isn’t collecting enough power. I know it can be done but I’m curious first, how to do it, and second, if it’s worth doing? Thank you very much for your input.

The engine in the truck is designed and built to move the truck. There are far cheaper to run and more effective options for direct charging any battery bank. You need a small diesel or possibly a quality OHC petrol engine on gas direct coupled to a suitable alternator, regulator and control system. The engine you are suggesting has the ability to spin up a huge alternator - possibly ten times bigger than needed for your purpose so expect fuel consumption to match.

A fixed speed stationary engine has much different cam and fuelling profiles, and a very accurate engine speed governor fitted to ensure the correct frequency and phasing at all times when the unit is under load. This means that the truck engine will be very unsatisfactory for your proposed alternative use.
