Starting problem

Sorry, that this is so long; but I wanted to make sure and include everything.
We have a 2000 Bayliner with a 4.3L Mercruiser engine, we just bought it in March and lake tested it there and it ran fine. We brought it home and changed the oil (it was black and nasty.) It took awhile to start, but we attributed it to a weak battery and took it to charge. When we picked the battery up from charging we were told that it didn't even need any charging.
Anyway, we had to move the throttle all the way forward to get the boat to start. We thought that we needed to do it that way since we might have bled the battery.
Anyway, this weekend I took the boat out and I could not start it. We had to have help starting it at the ramp. The ignition was loose, but I'm sure that's just because the nut behind the ignition was loose. Nothing major. The engine shut-off on me at the dock shortly after and I had to have help starting it again. The guy that helped said that I needed to make sure the advanced throttle button was pushed in and the throttle was moved all the way forward. I'm not sure if that's correct though. The boat worked fine that day, as long as I started it the way I just described. We did hit a rock that day and the engine shut-off, but fired right back up.
I'm not sure whether it was the rock or not; but the exhaust hose broke and the boat now takes on water. Not much water, unless we are sitting for an extended period of time. We were told that as long as the boat was kept running it would be fine, since the boat repair shop could not get to it that day. The next day when we got to the ramp it would not turn on, there was somewhat of a grinding noise when we turned the key. So we went and got a new starter and put it in. It ran fine, then the next day we couldn't get it started once again. There was no sound at all, turned out the starter cable end had broken off. We replaced that and it ran fine for a couple of hours. Then we turned off the engine for just a couple of minutes and we once again heard the grinding noise and the boat would not fire up.
I'm wondering what could be making the starter go out like that. We were told that the starter we replaced looked fairly new. Is there something else going on? The battery had a good charge and the cables look clean.
Please help me, I would rather figure out how to fix it myself than take it to the boat shop.
Thanks, Tiffani

Ayuh,... Welcome Aboard,....
It sounds like the boat has a multitude of Issues,...
It'd probably take a competent Mechanic awhile to sort it all out...
If you wanta take a crack at it,..
The factory manuals are available up in the Adults Only section at the top of this forum...

Re: Starting problem

I'm thinking that since we didn't have the first starter tested that it was probably fine (it looked fairly new)we just have an issue with the flywheel either not lining up correctly or we might have some teeth ground should check?

Ayuh,... You're probably Right,...

Inspection,+ Diagnosis is much cheaper than Throwing parts at it, Hopein' for the Best...

Re: Starting problem

Looks like the teeth on both the starter and the flywheel are still in pretty good shape. I'm going to get the starter tested today to see if it has any water in it.
We are going to replace the torn exhaust tubing and some other tubing that's in the same area. Do we need to pull the motor in order to replace them?

Re: Starting problem

Thank you for all your help. We were able to take it back to the place where we bought it and get a new bellows, a new ignition, and the starter fixed... all for free.
