RE: Mercury Saltwater 90 hp ELPTO
Guys, that's incorrect. Only the 115 and 125's drop two cylinders. The 3 cylinder 90 -- as an in-line 3 cylinder -- runs on all three all the time! The 115 and 125's are 4 cylinder o/b's, and drop two at the idle circuit.
By nature, the 90 runs a bit rough under 1200, but as a part-time tech, I can assure you that these are some of the finest running, most reliable motors out there.
