47 DB 2008 or 09

[Gimme Time]

Anyone out there that can give me some feed back on their DB issues that they have found that I should consider when looking at this boat?

Is the boat under powered with the QSC-600's which seem a little small for the weight?

I read where the station wagon affect might be an issue and if so how bad?

I believe the 18,000 BTU unit for the bridge is to small for cooling under way. Am I correct that it needs to be 24,000+ to cool it comfortably under way?

Can you tell me what the top speed is in knots when fully loaded with fuel & water?

Are there any issues with the QSC-600's that anyone is aware of?

Other thoughts or issues that you have become aware of with the DB would be greatly appreciated.

Feel free to PM me rather than listing on the open forum if you'd like and many thanks for your feed back.

I drove this boat when it first came out 2 years ago. I don't recall it feeling underpowered with the QSC 600's. Those engines are the same as my QSC 500's with probably a slightly larger turbo and fuel forwarding system. I haven't heard of any issues with the 600's but they are rated at 3000 RPM's rather than the 2600 RPM rating on mine. I'm not sure if the higher engine speeds will eventually lead to longevity or other maintenance issues. We tested the boat in Pompano Beach on a sunny 80 degree day. I don't recall the bridge air having any issues maintaining comfort. I didn't run the boat to WOT but I would expect top speed to be somewhere around 34-36 MPH. I wasn't crazy about the salon layout but that is a personal preference, otherwise it was a very nice boat and handled well. I don't know how many Sea Ray has made, though I have seen a few of them around the Northeast.

The 600's have enough horsepower but not enough displacement. Big boats benefit from engines with larger displacement and torque instead of small displacement with alot of horsepower. The idea being larger, slower turning props instead of smaller, faster turning props. Also, any 8 liter engine producing 600 horsepower will not last long. I have captained this boat a couple of times and was able to get 33 mph top speed with a very light load. No problems out of the ordinary that I have encountered with these engines compared to the 450,480,500's. One distinct advantage I see with this boat is the fact that it is a v-drive boat. The engines are mounted under the cockpit sole instead of under the salon. Every single bridge boat or aft cabin boat I have had experience with has always had two problems with the engines being mounted under the salon. One, the salon always begins to smell like a engine room after a couple of years. Two, the engines add quite a bit of heat to the living/salon area, a benefit in winter climes but quite the detriment in summer climes. When I first saw that Sea Ray was building this boat with v-drives and they were installed under the cockpit I thought it would be a hit for those two reasons alone but I have never heard it mentioned by anybody else.

Station wagon effect was no better or worse than other bridge boats.

In the summer 18000 btu is too small to cool a eisenglass enclosed bridge but so is 24000 Btu's. Hell, 100000 btu's probably isn't enough with all that un-insulated glass and hardtop. But my experience is in hot climates in the summer. I did have a 44 dancer with dual a/c units in the cockpit (34000 btu's) and it actually did pretty good on the hottest days.

Hope this helps.
