Just completed my purchase of a 450 DA today! Should have delivery soon. I cannot find a thread for this model. I thought I saw a link to another page? I have a ton of research and learning to do. Thanks!

Congratulations !
There is no special 450 DA thread here for this model. But a lot off owners who will give you good advice and help.
The 450 DA in combination with the 3126´s is a great boat. Just ask your questions :smt024

I should have delivery on Friday. The boat has about 1/4 tank of fuel in one tank. The other looks either dry or extremely low. I didn't investigate the fuel setup. But it appears we ran on 1 tank. Can we draw from either tank? Does genset only draw from 1 particular side? I have no idea how old the fuel is. My plans were to fill the boat when I get it and run both tanks. I'm going to carry extra sets of filters. Any additive?

The '96 450DA has a fuel manifold behind the pull down step on the interior wall of the cockpit on the port side. The manifold has 3 multi-position valves that allows you to select the source for each main engine and the generator.
It is kind of a danger signal when someone selects all the feeds from one tank. The unselected tank may be empty, it may be full of water and sludge or the tank may have a leak in it. My suggestion, if you do not have experience with diesel fuel systems, is to go to the CSR home page, look about 1/2 way down to the articles and read the one on diesel fuel system management.
You selected a great boat...one of the best Sea Ray ever gave us......enjoy her!

Welcome to the 450DA Owner's Club! We bought ours last November and have had an awesome season thus far! Frank Webster is a God-Send on this model. He has answers to any questions one could think up.

Noted but not addressed. The explanation from the owner was both tanks were nearly empty and he just put fuel in one tank for the sea trial. He did not use it. Original owner only has 350 hours on it.

Congrat's on the 450, we love ours..... And we are blessed to have Frank W as a 450 owner too, as he has saved all of our butt's at one time or another.
Boat is at Kent's Harbor on Brookville Lake but I am at 4 Seasons frequently......a few friends have boats there.

So should I fill both tanks and add an additive like Power Service Clear Diesel additive?

Read FrankW's article on the home page. It discusses 4 additives to use - especially a biocide. Order some Racor filters - they are cheap - and check/change them often after you treat the tanks.
I add all four at each fill-up and a shock treatment with biocide in the fall.

i missed the "more...." Button when reading Frank's post. That's perfect advice. Thanks
dual 200 gallon tanks?
I want to order the product today and filters so I'm ready for the weekend. Thanks!

You have 2-200 gal tanks, total of 400 gal. If it were me, on any boat where I have no confirmed history, I would: 1.) treat each tank with a shock quantity of biocide, 2.)treat each tank with Diesel Kleen for 200 gal (gray bottle available at TSC, Walmart, NAPA, etc.), 3.) Treat each tank with Stanadyne Lubricity Additive* 4.) add 1/2 gal of Power Service 9-1-1 to each 200 gal tank.
* Note: This is important because the engines in your boat were produced before the Feds reduced the amount of allowable sulfur in diesel fuel. In 1996, diesel contained in excess of 500ppm of sulfur. It is a natural lubricant so the injectors and fuel pump were designed to rely on the fuel passing thru them to lubricate the moving parts in each. Now, the fuel we get is limited to containing less than 15 ppm of sulfur, so we need to use a lubricity additive to ensure that the expensive fuel handling components on our engines are adequately lubricated.

I get my CAT filters (2 micron) from my CAT dealer - very reasonable price. Take your engine serial numbers with you and they can look them right up.
I use 30 micron Raycor elements for my primary filters.

thanks! I will do exactly as you have explained. I'm under the impression cruise speed should be 2200 RPM. With WOT being around 2800. Is this the range you normally operate?
How does that translate to speed?

Congratulations! Let the projects begin! Do you have any items that are driving you crazy and must be replaced/repaired? Like 19 year old plastic cup holders, camper roof top, broken ice makers, chipped fiberglass sinks... the list just goes on. But the boats are so much fun.
As to your question, for Chez-nous we cruise at around 2,000 rpm which translates to 19 knots or so.
