"Hi Everyone,
I recently had some boat work done at a local shop. They replaced the valve cover gasket and the boot around the u joints because i was taking a little water in. When i went to pick it up he also made mention that my rubber exhaust tube was old and cracked and should be replaced with the new upgraded one that Mercruiser suggests. The new rubber exhaust tube does not need to be connected on both ends and has a few slits in it to allow some exhaust out, for what ever reason. So they put it on. Now, i took it out and it was backfiring out the exhaust and had a general lack of power. I took it out a second time thinking it was just simply due to the kill switch not being properly secured, maybe it was causing some issues, but it did it again. It only seems to backfire when under a load. If im sitting at the dock i can rev the motor in neutral and its fine, if i put a load on it or if i try to run at a smooth steady RPM for to long it will backfire. I never had any problems with how the boat ran before i took it to the shop and had this work done.
I read another post where someone had a similar problem and the end result was that his exhaust was plugged. Could that cause this to happen? Should i take it back to this mechanic or did he steer me wrong on that exhaust?"
