Prepping for oil change on a '98 270 Dancer and looking for recommendations on oil brands/weight for Mercruiser 7.4MPI. I tend to think of this as a engine and leaning towards a decent synthetic oil as to not break the bank. Any thoughts to share?

My preference is the Mercuiser SAE 25W-40 synthetic oil and Mercruiser oil filters.

In my case, I have a completely full suitcase file carrier, plus a tall stack of manuals, just for the printed documentation for this boat. I also have many, many electronic files of documentation. My preference is to have both, w/ the hard copy always on board the boat.
WRT to your inquiry and observations, many of the fluids are for the engines / transmissions and are covered in the correct Mercury Factory Service Manual (FSM). The Mercury Mercruiser Service Manual 23 covers the 7.4L in all configurations and the 8.2L. It includes maintenance fluids.
There may be more current manual options. This one was copyright 1999.
Back to the overall manuals, I have manuals for all the systems on the boat, including things like steering, trim tabs, electronics, A/C, Vacuflush, windlass, the list goes on and on... None are covered in the Sea Ray manual, except to say they exist and to show the switches and breakers, as appropriate.
