460 DA Owners Thread

Have you tried doing an emergency start? Might just be a low battery not giving you enough voltage to spin it fast enough to bang the bendix out. I would use the emergency start switch and give it a shot.

Tried emergency start and that was the first thing I tried — sorry should have said that. I have plenty of voltage to port battery.
 
Made it home on one engine --- went super slow (approx 6mph) for a few miles home. :). Getting into the slip was loads of fun LOL. But we made it. Thank you to everyone for your help. I decided not to let that starter/bendix ruin our time out nor did I want to use BoatUS this time around. Thanks and happy 4th everyone!
 
Yes. Ordered it from fp and ran it overboard.
 
Happy July everyone!

Well, we are finally moving up from our wonderful 340 Sundancer! We are in the process of purchasing a 2003 460 Sundancer! We couldn't be more excited! This very long thread is proving to be invaluable!
 
We discussed cruising speed recently so I ran some numbers this weekend just to confirm. Full fuel load (to the brim), water, 650 lb dinghy on GHS platform, four adults aboard. Cruise was around 19 knots at 2240-2245 rpm, but we were heavy. So I backed it down to 2200, lower than we normally cruise and it dropped to 16.5-17 knots.
My point is that there seems to be some additional "oomph" in the way our props are tuned in the 2200-2240 range with the 6CTAs. Leaving the dinghy off and a perhaps a lighter fuel load yields a cruise of around 20 knots. The engines don't appear strained at this rpm if the WOT is at least 2650, to 2700.

Super helpful! Thank you.

We had also run numbers on a recent outing. My engineer son was kind enough to help and put together the attached data.

Happy July everyone!

We moved up from our 2002 340 with 8.1’s to our 2003 460 last fall. Absolutely no regrets: much better suited to our lifestyle and unbelievably easy to handle with just 2 of us on board! And by golly, given the price of diesel vs. petrol on the water, it is more efficient to run!
 
Is there a fuse for the bow thruster and the trim tabs? I have very low power on the thruster and currently troubleshooting whether or not the trim tabs are powered from those batteries in the back .

Thoughts?

I would suspect your aft batteries in the 24V system. They should be starting batteries of at least 900 cranking amps (MCA). This system also provides power to the GHS hydraulic platform. I change mine every 3-4 years.
The fuse for the Big Boy solenoid that controls the power for the Vetus bow thruster, is rated at 500 amps I believe. It is found on the engine room transom wall to port, beneath the Racor for the generator. Check it but it is probably okay.
Also check the hydraulic fluid for the bow thruster. The reservoir is under the V-berth up front.

Hi there. I have no idea when those two batteries were last changed so I went ahead and changed them. Wow what fun during a hot day —- what am I thinking? Oh and they are not made for a BIGGER man like me LOL.

Ok, I also changed the 200 AMP (sea blue) fuse while I was back there.

Still don’t have any power to my bow thruster…… I checked under the front bed to see if there is some type of fuse near/at the bow thruster itself but can’t find one.

Any other ideas? BTW, I also have a solid red light on my Promatic 21-3 charger.

Thanks,
Tim
 
I'll let the electrical experts chime in but perhaps your 24V charger (2430) isn't up to the task and maybe that is why you have the red light. You should check the circuits and connections first to see whether it is something simple. I replaced my 2430 about ten years ago and replaced the 1250 (12V charger) two years ago. Also make sure the charging profile is set to the chemistry of the new batteries. (There is a little selector wheel at the lower end of the case and it will be set to position 5 or 6 in all likelihood. Check your manual.
As far as power to the bow thruster goes, I thought that earlier you said there was low power but now there is none? Just clarifying.

Yes, correct. Previously the power was very low (with old batteries). The new batteries are the same profile as the old ones.

Do you think it would be the 7.5 fuse that’s coming from the charger that could be the issue?

When I looked up online for the Promatic 21-3, it says the solid red light = it’s on. Super helpful LOL.
 
Do you have the Pronautic Promariner 2430P charger, or the Pronautic 2430 C3? I have the latter, older model.
We might have different chargers.

Likely to have whatever the boat came with. Most of these equipment look stock/OEM from factory here and as they break, I’m replacing them.
