Re: I'm officially a boater! I hit a wing dam!!

Just another reason to be glad I have the GPS combo unit with the lakemater chip........

I'd really like to have that for the Mississippi or Illinois rivers, but I've never seen one available... just lake maps. :blue:

These are on my Wisconsin card......I'm sure that there are more portions of the river on the other states' cards.

Mississippi River Pool #1, Ramsey, Minnesota Mississippi River Pool #2, Ramsey, Minnesota Mississippi River Pool #3, Pierce Mississippi River Pool #4, Pierce Mississippi River Pool #5, Buffalo Mississippi River Pool #5A, Buffalo Mississippi River Pool #6, Trempealeau Mississippi River Pool #7, La Crosse Mississippi River Pool #8, La Crosse Mississippi River Pool #9, Houston, Minnesota Mississippi River Pool #10, Allamakee, Iowa Mississippi River Pool #11, Iowa/Wisconsin Mississippi River Pool #12, Iowa/Wisconsin

It looks like the Great Plains chip has the Illinois and Miss. rivers in the areas where I boat. Do the charts show wing dams, etc. in fairly good detail?

Re: I'm officially a boater! I hit a wing dam!!

Lakemaster stuff is available from Lowrance, Hummingbird, or Garmin?

Also, an update..

Had the local shop do a lower unit pressure test and prop shaft check, both checked out, got a new prop on (15 now instead of 17 to allow the +2-400 to hit max rpms)

But it seems the idle issue is still there.. I had to up the idle screw, but it seemed to allow me to turn it several rotations before any notice in rpm.. :|
Any ideas? It definitely has a heavy hit in one of the chambers I'm guessing?
Can an abrubt stop of an outboard disrupt the timing?
Thanks (It still runs but this is troubling after getting it to where it was at only to hit a wing dam.. sigh)

Re: I'm officially a boater! I hit a wing dam!!

sure.. could shear the flywheel key... check the timing

Here is an example from their site....highlights danger areas in red

Lakemaster was bought by the same company that owns Humminbird and MinnKota.

Looks like that has what I'm wanting... I see a new expenditure in my future!

Thanks!

Re: I'm officially a boater! I hit a wing dam!!

I'm surprised the wing dams don't have markers indicating their presence. All the wing dams on the river I'm on are clearly marked, though admittedly they are frequently hit by boaters who are unfamiliar with the area...................and not paying attention to the charts and markers.

Re: I'm officially a boater! I hit a wing dam!!

Ya, here in the Muscatine pool they're not marked. I did see a bumper floating where one is now that I found the map to mark them on my handheld gps.. about 30 or 40 of them? lol never did I realize there was this many.

Upper Mississippi River Navigation Charts

I did also check TDC and the flywheel and distributor marks are the same as what I saw pre-impact.. The guy at the local marina didn't have much to say, he thinks there might be a splined connector vs flywheel key..

I told him I figured it would be the timing belt since it's 7+ years old versus a bent rod or such in the powerhead since I would think the lower gears would be trashed pre internal powerhead issue...

Is it possible the distributor could have been turned by the impact force without turning the mark?

Is the only other options to check the spark (ignition gave out under stress?) and compression if it blew a cylinder? Is that even possible without affecting the prop shaft, gears, driveshaft, or flywheel/timing? lol

I thought to myself, would a 30 year old engine blow a cylinder if all the parts but the powerhead had been replaced somewhere along the way and is +xx years newer than the headgasket etc?

I would check timing with a timing light otherwise I dunno

So, a "wing dam" = a jetty?

At least your prop. doesn't look like this.

Re: I'm officially a boater! I hit a wing dam!!

no not all wingdams on the mississippi are marked by bouys but many are, and if you can play connect the dots you are pretty safe. watching the water helps too, you can see the swirls and rolling near them particularly near the channel end where the water moves at drasticly different speeds. also beware of crossing the southern tips of islands to close they often have sand deposits that extend quite a distance depending on water flow and those wont be marked unless by a good samaritan. another nice clue is birds that appear to be walking on water.....

the upper river nav charts that you linked to are great to have around, familiarize yourself with land marks that are on the maps so you can stay oriented as you feel out your area. i have some printed out and laminated for the area that i boat in from princeton to the north end of clinton.

Re: I'm officially a boater! I hit a wing dam!!

Is it possible that the distributor can be whacked out of time internally despite the distributor pulley being in the correct TDC alignment?
Or perhaps the stress of the impact caused the ignition coil or something to fail?

Getting a little nervous here... Doing a timing belt change and inspecting what I can see, but it seems aweful weird that everything else looks ok but it still has an obvious issue idling.. I was able to idle down to 600-550 when setting in gear idle to 650, now if idle approaches 800 in gear or out of gear it has a visible variance of +/- 200 rpms and usually dies over a 15-20 second period...

Could a moderator move this to the Mercury engine section, I think it's snowballed into an engine topic

Re: I'm officially a boater! I hit a wing dam!!

+1 on that, old Force 115 on a pontoon at the time, hit a rock wouldn't idle at lower RPM, seemed to run OK at higher RPM's. Found it sheared the key and flywhere was out alignment...

I was hoping this would be it, it's at the local marina right now.. Though I don't understand, wouldn't a sheared or partially sheared flywheel key cause the flywheel to NOT read 0 as TDC? I guess the flywheel and distributor pulley could still line up correctly but the crankshaft would be off a little..
