Hello all, I recently boaught a 1990 350 EC with twin mercruiser 7.4 engines, it seems that my port engine is having some problems, It has recently been serviced by my mechanic, but there is still vapour in the exhaust, also it seems the carb isnt woking that good, because it stalls if the engine isnt shifted in above 1000 rpm. I have found out that this carb is a rebuilt one, it is a rochester quadrajet, the serial numbers are 7040208 IA 3149. My mechanic says that this carb isnt the one for my engine. I want to mention that boat runs good and maintains the rpm, when under way. Please can someone help, also if needed where can I find the right carb for my engine if I want to replace it, thanks
best regards
JI
