NEVER buy reman's, and if you do NEVER for any reason trade in the originals for cores. 99.9 percent of what's being sold now is PATHETIC in both quality control and very low quality/incorrect parts used. Most are actually automotive carbs that are "marinized", and the companies doing them do NOT have a clue as to how to correctly set them up to work as well as a Marine unit.
We charge $175 labor plus parts and return shipping for Marine units. Turn around time is quick on them, as we know they are "seasonal" and we aren't doing full restorations and plating parts, etc........Cliff
