2000 Sea Ray 510DA twin 3196 best fuel economy

[Sundancer123]

Wonder where i could find at what RPM she will plan and what is the best fuel economy? GPH

attached is see

It seems Sea Ray assumes their customers have an unlimited fuel budget or simply want to run near WOT all the time when they recommend their crusing speed.

They published the same 2,100rpm cruise for my Sedan Bridge, but in reality the boat cruises more economically between 1,650 to 1,850rpm, so I think its fair to assume the 510DA is going to be right around there somewhere as well.

So unless you need to get somewhere in a hurry and cruise at 28+knots, you'll probably get maximum efficiency in the 22-24knot range.

You are spot on with your figures.

That looks like a page from the Sea Ray salesman's sales manual. If it is, the numbers come from a test of a new, not broken in boat with 2 adults, a CG kit, 50 gal of fuel, no water, no waste ,not food, no beer or mustard in the fridge........in other words, real light. You ain't gonna get those numbers....period.

You will get the following fuel burn numbers...per engine, no generator running:

2300rpm = 33.1 gph (WOT)
2200=28.0
2100=23.9
2000=20.5
1900=17.3
1800=15.0
1600=10.8
1500=9.3
1400=7.5
1200=5.3

Get out your calculator..........but with the 510, you will find what most big boat guys do. You will pull the throttles back to a sweet spot where the engines don't work and the sound levels are decent because the trip is usually more fun than the destination.

when would you think she plains?

I can't help on that. The only one I've run had 800 hp 3406's. The damned thing almost planed at idle!

No wake areas were transited with trolling valves activated and one engine out of gear.

The Cat Spec sheet from 6/19/2001 Rates the 660HP 3196TA at 2300 RPM Max WOT and list a Max cruise speed of 2100 RPM. However, CAT also rates a "Max Continuous Cruise" at 1900 RPM.

...... The only one I've run had 800 hp 3406's. The damned thing almost planed at idle!....

I'm diving this Sunday from a custom built 50' dive boat with a 17' beam. She runs a pair of 800HP CAT 3406s. fully loaded with 12 divers and the 'gear' of 12 divers plus crew, air compressors, etc, etc.....I'd say that's fully loaded....this boat will still cruise at 25 knots!

The boat was custom built in 2001 by Chesapeake boats in Crisfield Md.

 

[Sundancer123]

3406s dont seem to make sense
suck alot more fuel for 4 kts?

The 3406E's are great diesels...they make a ton of sense and will make even more sense when your crusing 4/5knots quicker on long hauls.

Talk about a thread hijacking....that was 4 alarm terrorist attack. WTF

 

[fwebster]

You obviously haven't run a 510 w/3406's..................and apparently haven't paid attention to the aftercooler issues on 3196's.

 

[Sundancer123]

Aftercoolers aside.

The specs show 4 kts difference..

660 vs 800 hp

140 hp X 2engines on a 40000 lbs boat

So 280 hp on 40,000 lbs- makes a performance difference?

Come on

 

[fwebster]

I'm not going to argue what Sea Ray publishes in marketing poop, but when you load the boat as most of us do, the real difference is more than 4 kts. The 3406 boat runs and handles like a sports car.........the 3196 ones run like a big heavy boat.

Theres a 3406 510 around my area and the thing flat out hauls you know what. Even with the trolling valves activated the boat probably drops 3 or 4 inches down in the stern when put in gear. I also feel that the 3406 motors don't have anywhere near the turbo lag that the 3196's have.

3196's take a little time to plane out (at least on the 500 Sundancer I have run with them) and the 3406's jump out of the hole.

Also, I have seen a 500 and a 510 slipped next to each other and I never knew there would be that much of a difference in size.

 

[fwebster]

In my opinion the 510 is absolutely the biggest 51 ft boat you will ever see.

 

[Skuza]

510 is gotta be one of my favorites. Like Frank says it is a monster! Very deep hulled boat. I would love to drive an 800hp version after reading Franks comments!
