The Rangers are described as the Swiss Army Knife of boats! There is a lot of amenities and a lot that can go wrong. My suggestion to anyone buying a used boat is don't expect a name brand boat to maintain itself.
When buying a used boat you have choices.
(1) Purchase a turn key boat that the owner has taken care of and is able to demonstrate that all systems are in working order and can show a full yearly report of the maintenance schedule that was annually completed. With this should come a complete 1 or 2 day orientation of the boat. This is hard to find and this owner will be very proud of his boat and expect a proud price.
(2) Purchase a boat that looks clean and may need a few things but know that every system on board needs to be inspected and shown to be fully operational. Best way is to have a full engine and Hull survey. Negotiate a price based on surveyors findings.
(3) Purchase a boat that has been sitting for a while probably needs to have some work done to make it a fully functional boat. Plan on investing some money in the boat to bring it to a fun functional boat and adjust your offer price according to what you feel will be required to get the boat ship shape.
Option 3 your not going boating for a while!
Why am I explaining this? You feel you purchased a lemon. Probably not! You purchased a boat and had a survey done based on information that you posted in a previous thread.
"Yes, the boat received it's 1000 hour service then was taken for sea trials by the surveyor. Oil samples done on both engine and generator. No apparent issues"
Based on this you probably fall into option (2). I am assuming the surveyor inspected all operating systems and found no discrepancies. The report came back that all systems on board were fully functional and the boats condition was in good operational condition. The 1000 hour inspection which includes all annual maintenance recommendations + the requirements from the 1000 hr.
• Draining the fuel tank
• Replacing the fuel fine filter
• Replacing the fuel filter/water separator element
• Changing the engine oil and replacing the engine oil filter element
• Replacing the seawater pump belt
• Replacing the anodes

• Checking flexible engine mounts
• Checking the fuel pump and fuel lines
• Draining and refilling closed cooling
system (engine coolant)
Two items I would include would be removal of after cooler and heat exchanger for cleaning and inspection. No where in Yanmar's service intervals is this included.
The fact that you had this 1000 hr service completed should have given you insurance of a good operating engine. It did't why? (1) its mechanical and mechanical items can fail prematurely or (2) the servicing center failed to complete all recommended service items. The 1000 hour service complete is approximate $3000.00+.
The codes that are showing up are injector codes.
PO 273 is injector # 5 and PO 261 is injector is injector #1 There are many reasons electrical or mechanical. The fact that you had a fouled fuel system may have contributed to the injector codes. I would advise having a certified Yanmar dealer inspect the engine.
The battery charger turning off may be a breaker issue (weak) or the charger has failed and causing a high amp draw. Could also be a poor connection. The best way to troubleshoot is keep it simple. Look at the connections tight and clean. Then research the owners manuals ( most can be found on line based on the model number of the equipment. If you are not a DIY boat owner make a punch list of all the failed components or issues at hand. Be very descriptive in the punch list. Go to a good servicing marine repair center and get an estimate for the repairs. Once you get items fixed learn the boats systems so you can from this point forward maintain them. Purchasing boats can be frustrating New or Used they are not all 10's in fact most are 5 to 6 new or used.
I feel your pain ! Once you get things fixed you will enjoy your boat. Good Luck.
