I've got a 2006 200 Opti in my SportJon and while running the river a couple weeks ago sucked up some mud and weeds while leaving a friends home on the river. Sandtrap did it's job and I noticed that the engine was getting a little warm on the way home. I limped her home and inspected the next morning.
What I found aside from a choking sandtrap was that it appears that the expansion chamber became very hot melting wire looms and anything plastic surrounding it. I flushed the motor with a hose attached to the flush fitting for quite a while. I'm in the process now of replacing with new any wiring loom/wires/hoses that were affected.
My question is this and I'd like to refer you to the attached image...
1.) There is still water in the 2 exhaust chambers, should this not drain? I've always been told that these motors are self draining and considering I'll be winterizing her sitting out in subzeero temps this concerns me. Is it standing water from the flush and not starting the motor afterwards to blow that water out of there?
2.) Refer to the 2 rectangular exhaust ports again and you will see that on the left port a portion of the metal housing is missing. It's a small portion and I've been told that it won't hurt anything that it's gone and that it most likely blew out the exhaust at some point...thoughts on this?
I appreciate your time looking at this, it's a depressing time getting her ready to be put away for the winter...
