2007 210 Select bowrider 5L MPI motor Alpha outdrive. So, Saturday I got the boat ready for summer, ran the muffs on it for a minute or so in the driveway - and ran good, so took it to the lake, drove a 1 mile loop on the water, brought it up to 4500 rpms, for a bit, then back down to 3500 to check things out and then put it in the slip for the summer. Got back to the house, and noticed half consumed chestnuts on the ground where I'd run the motor, looks like they came out of the exhaust pipe. So, Yesterday (Monday) I went out on the boat, drove it a mile to an island - it was very windy/choppy, so I only ran at 3,000 rpms or less. 3 hrs later, went to leave and as I start to bring it up to speed, around 2200 rpms, got an alarm, system error ? Was seeing voltage readings on the smartcraft display. Ok, shut the motor off, turned off the system, checked the engine compartment, everything looked ok. Battery terminals are tight. Started it back up, seemed to be running ok. Brought it back up to 2200 rpms or so, and got another system error alarm - this time, noticed oil pressure up near 100!? reset the system again, checked the engine compartment, still no signs of any issues. ?? So, I drove it to shore for a mile, but kept the rpms under 2000 and no more alarms??? Any ideas - what could these rodents of done up in that exhaust section? Aren't there mechanical flaps blocking those exhaust manifolds to keep water/other objects out, etc? I guess I need to do some more digging - I didn't think to delve deeper into the Smartcraft alerts at the time. I wish Smartcraft had a better diagnostic interface.
