While boating over the weekend, I lost the Y-pipe (downtube). I have a feeling on know why. When I installed the FAE system, I could only get one of the outer hose clamps on each side to overlap the 90 deg elbows coming off the exhaust outlets. My exhaust outlets must be farther apart than others or the elbows were not long enough. Anyway, the tube is gone and now I don't know if I should be running the boat without it. I am worried that there are no exhaust flappers on the boat anymore that water could get up into the engine (especially in reverse) and cause some damage.
Any thoughts??
Here are some pictures of after the install but before I lost the Y-pipe. Only the outer hose clamp on each side made contact with the elbow coming out of the exhaust openings.
