Hello. We've got an 18' Sea Pro CC with a 2002 90hp Yamaha o/b. This past weekend, we ran over a large log floating in the middle of the river (it was almost totally submerged and hiding in the chop in the middle of the channel; we didn't see it until it was right in front of us and were unable to completely avoid it). The motor hit it with a decent thunk then died a second or two later.
The motor had been running okay up until that point, maybe a little bit rough at idle. Now it won't idle without the emergency enrichment switch open. With the switch in the normal position, the motor will start, run for a couple of seconds, then die. With the enrichment switch in the open position, the motor will run okay (this is how we managed to get back to the dock after striking the log), but will die when we try to run at very low speed.
Visually I didn't notice any major looking damage, other than some paint rubbed off the propeller and a scratch at the front of the lower unit (right at the oil drain plug). I'm guessing the impact knocked something loose or out of adjustment, but am not sure where to begin. It seems like something is preventing fuel from being delivered correctly, but I just don't know enough about how these motors operate.
It's likely that I'll end up taking it to a dealer for repair, but would like to have some idea of what I'm dealing with in case it's a relatively easy fix. Any suggestions on things to look at would be most appreciated.
Thanks!
