Hi guys. Going to do my PM this weekend and was reflecting on an issue I had last year.
Dropped the boat, wife goes and parks the truck, I go make High speed pass while she's walking around. (Yeh, I know.....)
Anyways, got a hot smell, noticed water pumping out of port exhaust bellows.
Return to dock ASAP, while idling waiting on the Jackwad to launch his boat, he's in the water, on the trailer but now decides to load his boat. Motor running rougher and rougher. Finally dies.
Lift hatch, water pouring in back of boat. I am sinking. He finally clears, but I'm dead and now have to ask him very politely and calmly to tow me back. He responds sarcastically, what's the matter, forget the plug? I really, REALLY wanted to unload on him, but I REALLY need his help as I'm going to go bow up pretty soon. Got it out, got it drained. So WTF happened??????????????
The port flapper had blown off. No problem running wide open. Somewhere on a decel, the lower exhaust pipe had filled, pressurizing the bellows and blowing it off the tail piece. Creating a 4" hole in the stern...... I have underwater exhaust.
Had spare flappers back at the garage. Got it cleaned up dried out, installed the flapper, reset the bellows. Check oil for water intrusion. all good. Enjoyed the rest of the weekend.
FYI, everything is double clamped, except the flappers. Not enough room for a second one. The flapper did not break off, it slipped off. Now I know what happened, I carry a spare. I can drop in the water and fix it.
By far, my scariest moment boating.....
What did I learn, check the flappers....................
