Im looking at a 2000 sea ray with the 150 opti on it. The unit has very low hours and lruns good. I have, however, heard lots of bad reports on these engines for that year. Any first hand experience out there??
There are service alerts on all the optis.Some are pidally and some are substantial.The only way to tell if your engine has been updated to the current standard is to run the serial # by Merc .
