Official 390 E.C. Thread

Yes, fortunately State Farm took care of almost everything. They even insisted on repainting the entire bottom of the boat (I’d just had it cleaned and painted six months before). I had a deductible plus the costs of adding the dripless, but they were wonderful to work with.

It appears that a boat gets towed in every day from this section of the Pungo-Albemarle Canal on the ICW; we were the statistic for that day.

Unfortunately, in my mind it was similar to a car in a snowpile and thought I’d rock it out. I’m the one who screwed up badly there.

The pump in my shower sump is not running. Before I go digging into it I would like to make sure there is power to the circuit. Does anyone know what breaker it is on or where the wire run is?

Well I found the origin of the hot wire to the shower sump. It is on a breaker min a breaker panel on the forward wall of the bilge with the alternator and waste macerator breakers. It is always on like the bilge pumps, which makes sense , since the AC condensate is plumbed into the sump also. There is power to the terminal strip just outside the tank so I guess the problem is the float switch or the pump.
 
Now for my next problem.

The full and don't flush lights for the crap tank stay on even though the tank is empty. Is this a float sensor, capacitive or resistive.

I am guessing float and it is just clogged or stuck in crap. Any suggestions before I start digging into the tank?

Unless it's been replaced, it should be a float. I have the same problem as you. Lots of people recommended putting dawn down there with a lot of water and then taking the boat out to shake it loose, but I've not tried it yet.

Does anyone know the owner of a 390 EC named Donna Cay II based in Cape Coral Florida?
It is for sale and I have been trying to get ahold of the listing broker for quite a while with no response.

If anyone knows the owner please puit them in touch with me.

Thanks,

Actually I own it, just bought it a few months ago, in the middle of some repairs but have listed it back on the market as my wife wants a bigger boat that we can live on in the 60ft range.

the rollers are very similar to sliding door hardware. remove them and go to lowes or home depot. they have something similar that u can adapt to make them work

Hey Ken,
I am in need of rollers also.
Did anyone get back with you on this?

Overboard Discharge System?

That’s actually a more polite way of saying pumping out your holding tank directly into the ocean; it’s prohibited within 3 miles of shore (ocean only). Generally speaking, you’d never have to do this because almost all marinas in the US have pump out stations. Unfortunately, these aren’t common in the Bahamas. According to the marina operators we spoke with, there are none. We couldn’t find any on Bimini Island, but we did find one on Grand Bahama Island.

Our boat was built with a “Y” valve to shunt the effluent from the holding tank down to a discharge port underneath the boat. The “Whale Discharge Y Valve” is moved from closed to open and the handle on the brass seacock is opened, and the key is turned… and if everything is working properly the poo and goo go flying out underneath the boat. The Coast Guard will check this “Y” valve and it must be locked at all times within 3 miles of shore.

Unfortunately, the previous owner had removed both the handle to the whale valve and the handle to the seacock… so we had no way to handle the required discharge and there were no pump out stations.

My suggestion to each of you would be to make sure yours is in working order and then lock it down.

WOW...I have finally found something in common between Italy and the Bahamas..... No pump out stations, anywhere!!!:smt013:smt013
 
Re: Something bad already happened....

I'm new here but have a major problem and I hope that someone here can point me in the right direction.

Yesterday I developed a vibration on the starboard side. I shut down and went over the side to investigate but found nothing amiss so I continued on my way at reduced speed. The vibration continued for another 1/2 hour when suddenly the shaft snapped just behind the strut. Having lost the prop we continued to limp home on one motor.

I need to know the dimensions of the shaft to have a replacement made.

Does anyone have this?
 
My shafts are 1 1/2 and I think that the one that broke was original to the boat. I had the other shaft replaced 17 years ago. I just need to know the overall length for the shaft so that I can get a new one made locally. The broken shaft was Aquamet 19 but the port side replacement that I had made was Aquamet 22.

Since I have the coupler and inboard end that part is easy. I'm just missing everything past the strut.
I hate to have to remove the port side shaft to use as pattern.

I sure would like to see a closeup shot of the broken end of the shaft. How did this happen? Electrolysis? Piss someone off and they took a hacksaw to your shaft?

That is a typical break point for a bent shaft. The gas 390 has a small dia. shaft, so when there is a bend, the end of the shaft whips aft of the strut. metal fatigue eventually takes its toll and the shaft breaks at the aft end of the strut.

The shaft length is a matter of record with Sea Ray, the taper, the keyway dimensions and the threads are all standard. You should be able to get the shaft specs from Sea Ray Customer Service which would avoid any work on your boat other than remove and replace the broken shaft and lost prop.
 
What I find most interesting is that there was no prior vibration reported except for the last 30 minutes before the catastrophic failure. As an engineer - I am very interested in the cause of failure. If you had a fatigue failure there would surely be some prior long term vibration. He said they were 1.5" shafts.

the gasers come with 454 340-350hp his signature states 8.1liter I think those are 502ci each liter is = 61cubes 385 hp maybe the shafts arent rated for it????

been a ruff year so far for us
2 shafts
missing rudder
missing prop

hope it gets better for our family here
 
my shaft broke without any warning too, but this happened some 10 hours after installing the 4 blade props.

I really believe the original shafts are somewhat under sized... I now have 45 mm (1.77") Aquamet 22.
 
Actually the engines are Crusader's version of the GM 496 CID truck engine. Great power choice for the boat since they have much more torque at 3200 RPM than the 454 putting out 300 hp at the cruising sweet spot. Max RPM (rev limiter setting) on this version is 4600 but they made an HO version that will spin faster and has a higher cruise RPM. When I put the engines in 13 years ago the prop shop told me that the older AQ 19 shaft was marginal with the ZF 2 to 1 ratio transmissions. The engines are rated to turn as high as 3600 continuously and at that RPM 30 MPH is possible in calm water. I took the boat from Newport News up the Chesapeake Bay/Potomac River to the DC yacht club at this speed in summer of 2013. Eight hour run, approximately 250 miles without refueling.

I reached Sea Ray Customer Service and got the shaft length so now I can get started on the repairs.

Stay tuned......

Remember - BOAT stands for Break Out Another Thousand
