Few questions about a 1985 Sea Ray 270 Sundancer!

I am looking at purchasing a boat that a buddy of mine owns. It is a 1985 270 Sundancer that is in reasonably good shape. It is powered with the dual 190hp 3.7 liter inline 4-cylinders. The Port engine has 180 hours on it, and the Starboard engine has 800 hours on it. The motors run great, and it is in great shape overall. I have owned quite a few smaller boats, but never anything over 22 feet.

So, I have a couple of questions. First off, is the battery charger unit. The boat's owner ran the boat ~6 weeks ago on an off shore fishing trip and came back in pretty late. He claimed that the converter wasn't turned on which allowed the batteries to die. Another boat owner at the marina was arguing that the converter has nothing to do with charging the batteries, and I am honestly clueless. I understand that there is a trickle charger on board to maintain the batteries. It appeared that it remained energized whether the converter switch on the main circuit panel was on or off. How exactly are all of these wired? Also, the battery tender was registering only two batteries. Shouldn't it be wired up to all three batteries?

Next, I have a question about the freshwater system. The boat has a pressurized freshwater system. I seen that there were two different fill ports on the aft-port corner of the boat (one pressurized, one normal fill). The current boat owner was claiming that he never used the water system underway, and always just used the pressurized port. Does that port completely bypass the water pump? Where is the freshwater pump located? Or should the water pump still run when the pressurized port is used? Once he hooked up the pressurized water, it appeared that all faucets and the toilet (vac-u-flush) worked great.

Finally, I have a question about the Macerator pump. Right now, it appears that the macerator pump is hooked up directly to the tank, and can pump overboard just with the flip of 3 switches (can't remember their labels, but they were in the head). Isn't a Y valve required? Can the tank be pumped down at a pump-down station without a Y valve? Where should the valve be located? Shouldn't there be a discharge valve to open prior to pumping down the system? Where would that valve be located? Is it manually or electronically operated?

It just seems that the previous owner really had little knowledge of the boat. He didn't use it much aside from doing short trips out and back for fishing (and never used the head/freshwater/stove/fridge systems while underway). I'm just wanting to get my head wrapped around all this so I can have a clear vision of what I'm getting into before moving into the project. I understand that I can get a survey, but I don't feel one is necessary in this situation (I'm not paying much for the boat, and I know for a fact that there are no soft spots, gel coat blisters, motor damage, etc...). I am very mechanically minded and can repair most anything on the vessel once I get her.

Thank you guys in advance for any input!!

Hey BigWill, The battery charger or AC converter only charges your batteries when hooked up to shore power. The charger should be hooked up to all three batteries. Under way the alternator will charge the batteries and the volt gauge on the dash should be showing about 14 vts. while engines are on. You should have a fresh water tank and a water pump, you turn the pump on at the helm. Should be a rocker switch for water pump. The pump will run till the correct pressure is built up in the lines. Your vac-u-flush will pump waste into the waste tank. You should have a discharge hose that will go to a y connector or a t. One hose should go up to a deck fitting where you can have the waste pumped out, the other hose will go to the macerator and then to a valve the is mounted to a thru-haul fitting. This valve should be turned off and the handle removed. It is illegal to dump waste overboard unless you are off shore the correct milage. No valve has to be opened or closed to pump out the tank with dock pump. I love my 270 and have enjoyed many trips. Sea Ray are very well made boats and perform very good. You can't go wrong if the price is right. Go luck and let me know if you have any other questions.
 
Awesome, thanks for the reply!

I now only have a few more questions left. First off, where is (or should) the freshwater pump located? Where is the holding tank's pump-down port located? Where is the thru-hull valve located for pumping the holding tank overboard? I really wish the previous owner tried to learn this boat better in the 3 years he's owned it. He has meticulously maintained the boat and has had good marinas do all of the work. But, he honestly has no clue how to even use 90% of the stuff on board. In fact, he has never used the alcohol stove either. There is also a Lowrance fish finder, chart plotter, and depth sounder installed that he has never even turned on. I hooked up the wires to it (which were just hanging), turned it on, and it still worked! He just used it as a glorified off-shore fishing boat and only drove it ~15 miles from his marina at most in waters he knew so he never even used charts, gps, or any navigation aids. Seems like a waste of a good boat to me!

Not sure on an 85, but the fresh waer pump should be located adjacent to the water tank. on my 270 it underneath the aft bunk, the tank is centered and the pump is on the port side. My discharge thru hull for the waste tank is on the starboard side and visible in the ER where the shut-off is located on top of the thru hull fitting. The lever should either be removed or wired shut as it is illegal to discharge sewage uless several miles off shore.

First - Welcome
We have the same year boat. The fresh water pump should be mounted between the gas tank and the water tank on the port side of the boat.
Ours gets used all the time. If needed you can get replacements for a few bucks less at RV stores.
I'd be careful if trying to use the alcohol stove if it's been sitting a long time. Ours was never used either and I had the hardest time getting it to work properly. Ended up damaging some of the vinyl next to the sink with a flare-up. I have since replaced it.
