I've always been relatively dissapointed with the performance of my boat (after yesterdays prop testing session, now I'm really dissapointed).
Anyway, my 1988 350 Magnum (the Carb version, originally rated @ 270HP) has a replacement Qjet on it. I have what appears to be the Merc technical manual for 1988 and it lists all of the QJet part numbers for the various Merc engines that year. The Replacment I have is listed as the stock carb for the 260 motor. It appears that the only Carb difference between the two motors is the Secondary Metering Rods. Merc lists the 260 as having CH metering Rods (.036") and the 350Mag as having CL (.042") metering Rods.
I pulled the metering rods out, and shure enough, they are the CH rods for the 260.
So, after all that - here's my question. Should changing out the metering rods give me any appreciable difference in performance on the top end? And if so, where can you buy just new metering rods?
Thanks!
