In this video, Eric Sorenson gives a brief overview of the generator system operation for the Express 330. Other models' generator systems operate similarly.
Many Grady-White models
29 feet and larger have standard or optional generator(s) which can
power AC electrical systems including air conditioning when the boat is
away from dock power, making the Grady Life even more comfortable.
Grady-White locates generators in a rigging compartment below the
deck for quiet, clean operation. Access is through on easy-to-use aft
cockpit hatch. The generator power system is operated from the
electrical panel located in the cabin or console.
Grady-White installs generator(s) that run off diesel fuel, and we
provide tank capacities for many hours of continuous operation.
Generator diesel fuel tank fills are generally located beside
Before starting the generator–with its cooling water seacock
closed–ensure that the raw water strainer is clean. Remove the
generator’s integral enclosure (designed to help keep the equipment
quiet and dry) and check the generator engine oil fill level. Also check
the cooling water tank level. Then, reopen the seacock. Remember
there’s a carbon monoxide (CO) detector located at the aft cabin
entrance, and make sure it’s in working order. You can find the
locations of all of these features in your owner’s manual.
Now you’re ready to start the generator. The generator control panel
is located at the bottom of the main electrical panel. Check the fuel
gauge for adequate fuel, ensure the control panel on/off button is on,
and then hold the start switch for 3-5 seconds until the generator
starts. (On the Express 360, the start button should simply be depressed
and released. On models other than the 360, if the generator doesn’t
start after 10 seconds, release the switch, wait a minute and
An interlock bar prevents shore power and the generator from
supplying power to the electrical panel at the same time. For generator
use, turn AC loads off, turn the shore power switch off, slide the
interlock bar up, and switch the generator on. Now turn on the
individual AC breakers needed. Reverse this procedure when hooking back
up to shore power. Once shore power is supplying power to the electrical
panel, turn off the generator and close its cooling water seacock.
