If i get the loan it may throw a wrench into my rebuild plans and money. All depends on the payment.

You CANNOT remove the oil injection from a DFI engine. DFI engines inject the fuel directly into the combustion chamber, so NO fuel goes through the crankcase, only air and oil that is injected. Most newer DFI's inject the oil directly into the main bearings now to furthur reduce oil consumption, and with no fuel going through the internals of teh engine to wash the oil off they use even less oil. DFI's though are VERY picky about what oil you use, and should only use an ashless 2 stroke oil with carbon removing additives which means you need to run a DFI oil(conventional 2 strokes do not have the carbon build-up problems as the fuel going through the engine prevents it. OPTI's though also use the oil to lubricate the air compressor, so cheap oil will not only carbon up the engine, but will trash the compressor with it. MANY DFI engine failures are DIRECTLY a result of using cheap oil in them. OPTI's are not bad engines, aand neither are the FICHT's, but early ones did have growing pain issues as it was such a new technology. As for how to tell the hours, a MERC dealer can hook it up to the scanner and tell you as the ECM keeps track of how many hours and at what RPM's.
