Re: ETEC 250 history report
Not sure exactly what the "no oil time" means, but BRP claims the E-Tecs can run up to two hours w/o oil and no damage will occur. Not sure I'd want to test that, but I wouldn't be too worried about it. Do a compression test on all cylinders. You should get > 100 psig and even (+/- 5% deviation is OK).
I would ask a dealer to help intrep the results. I've had some short term overtemps on my E-Tecs caused by running in very shallow water and sucking up stuff that stuck in the stats. I would be more concerned about the very high top temps seen in each engine, but if the compression is OK, you should be good to go. The high EMM temp is also a concern, but if the EMM is still working, I wouldn't be too worried. The shift thing looks like something the owner just ignored and isn't usually a big deal to fix. It could be just an adjustment. I would check the engine carefully mechanically particularly the gearcase. Look for any water in the gear oil, metal chunks, etc. If it's possible, run the engine on the water at speed. Running on the hose won't tell you anything other than it will start and run.
I'm surprised your report isn't much longer. Typically there's a bunch of current status info, length of time spent in a number of different RPM bands, etc, etc. Most buyer of used engines do not have the ability to know any of the stuff that's in your report, so consider yourself lucky to know the actual engine hours and all that other stuff.
