496 MAG HO Lost Drive HELP??
A buddy that boats with me had this happen:
Should note boat has 496 MAG HO, with Bravo 3
The Rinker went down on the maiden voyage this past weekend. The boat cranked up and ran fine on the hose for about 30 minutes before I took it to the river. Came up to temp fine, no unusual noises, alarms, etc. Put in at Ditto, fired right up, idled just outside the marina and sat there for about 20 minutes or so at idle. Again, no problems whatsoever. Once Harley and Justin got to Ditto, we ran maybe a few miles up river. The trip was "spirited" at times, but not like dogging the boat or anything.
Maybe a minute or so after we stopped to tie up, the engine started to shutter, an alarm sounded, then the engine shut off. I popped the hatch and noticed the drive fluid reservoir was almost empty, so I topped it off (which took about 10 ounces). It started right back up but almost as soon as I put it in drive, the engine shut off again. At this point, it wouldn't stay running for anything. It would turn over and start but not run. Justin towed me back to Harley's boat, where we let it sit for a little while. After it sat for 10-15 min, Harley asked if it would crank and sure enough, it fired right up. We let it run for a minute and decided that maybe it was no longer in "Guardian Mode" and I should try to make it back to the dock. We didn't make it a few hundred yards and the engine bogged and shut off again. I popped the hatch, checked the drive reservoir and everything looked ok. I cranked it back up, got on plane again, and it started bogging. Just as I was backing out of the throttle, we heard what I would call a very dull grinding noise and the boat stopped. I tried forward and reverse and had nothing. I shut it down, and let the guys know we were dead in the water. Once they got there, we tried a few things but again, it would start but not run. We tried to the point of draining the batteries which is where I am now.
Here's EVERYTHING that changed on the boat from the end of last season when it ran just fine, to this season:
-Changed fuel filter
-Changed oil and filter (used quicksilver 25W40 as recommended by the manual)
-Changed drive fluid (used quicksilver high performance gear lube as recommended by the manual)
-NOTE: The manual said it would take 100.5 ounces of fluid, but my reservoir overflowed with just under 96 oz. Possibly the reason for the low fluid while running the boat. I did add the fluid using a pump through the drain plug.
-replaced fresh water impeller
-NOTE: One of the air line fittings broke off of the housing. This is used by the hand pump when forcing the water out of the sytem to winterize it. I thought it insignificant, put a cap on it, and ordered another one.
Also, I pulled the cover from the top of the drive and found some dreaded metal shavings. Interesting thing is, I did not drain the drive before doing this, yet there was no fluid in the top of the drive. Also, the reservoir still shows the fluid level to be in the acceptable range. My initial guess is the drive is shot because of a major air pocket that is still somewhere in the system?
