If the transmissions are Hurt or ZF, then you wash and rinse the filters the re-install.
Look at t he plate on the back of the transmissions for the type fluid. Do Not Use Dexron !!! in Twin disc transmissions.

Just bought a 2012 450DA with Cummins 380’s and Pod drives. Looking forward to learning more about it on this forum.

So far, we've had our 98 450DA for a few weeks and have been loving it. It hasn't been all smooth sailing, but over-all it has been a great addition to the family.
We sucked water into the Westerbeke on our first try. Didn't over-crank it or anything - it's not my first diesel or generator. I'm thinking that it was a perfect storm of weight distribution that lowered the transom enough to make the difference between "almost too low" and "too low" - which put the siphon break below the height where it should be in relation to the engine. At the time, we had full fuel tanks, full fresh water and a giant TNT lift on the back. In my forum surfing, it seems that some guys have nothing but trouble with their Westerbeke and some guys have no problems at all and love them. I'm wondering if the difference is in the weight distribution? For example, guys with standard swim platforms and no Cablemaster have a center of gravity which is forward from the CG of those of us who have all of that gear on or aft of the transom. All that additional weight so far aft possibly lowering our transom and lowering the generator in relation to the water line.
I don't know - just a thought - while the mechanic was pumping out my cylinders.
We pickled the engine for a few days until a newer version of the anti-siphon valve arrived from Westerbeke and then pumped out the oil. Drained and flushed the oil, ran for 15 minutes, drained and flushed again, ran, drained and replaced the filter. All seems to be running well now. I'll be extending the hoses leading the the anti-siphon and moving that up as high as I can to eliminate the chance of this happening again.
Something else we noticed - it would be very easy for the tiny rubber one-way anti-siphon valve to be installed backwards within its cap, rendering it useless. Dumb, i know, but easy to do.

TBC, I just wanted to thank you for all the help you provide! Although I sold my 450 some time ago I read CSR everyday. I always notice you helping out. It is greatly appreciated. JC

Upgraded the galley lights yesterday. Removed the old fluorescent lights and replaced with LEDs. Home Depot sells a two pack. Just used the inside of the sealed fixture. It can also change colors from soft white to warm white to daylight.

Does anyone know if it's possible to replace the bulbs in the helm switches with something brighter? Or does the whole switch have to be replaced?

There aren't individual bulbs. Sea Ray used a foil strip light system that is powered by a small inverter. There is a potentiometer on the dash that varies the input voltage to the inverter so you can dim the lights. It may have seen too much salt air andbe internall fouled with corrosion. The inverter is locatd behind the dash and is probably the culprit.
Two other facts I can share……….Mine worked flawlessly until I replaced the dash panels and installed led lighting behind the panels……….the other is the fact that the inverter turns 12VDC into 120VAC so be careful putting your hands around the light strip with it is activated because it can knock you on your butt if you aren't careful.
