17 Foot bayliner with 3.0 mercruiser and alpha 1

Ok...Fly wheel went bad, pulled motor and fixed. Had a hell of a time getting the drive back in. Take it out for the first time yesterday and everything was great for a couple hours. Driving along at almost full throttle and the I can hear something kinda slip and it brings us to a stop. Motor starts up fine but wont go into forward or reverse.

Please help! It's 90 today, it never gets this hot in Alaska!

Thanks!

Does it overheat when you run it? Did you check the alignment before you put the drive on?
Look back by the coupler. See any metal shavings around it?
Start the engine, and see if the shaft going into the drive is turning.

Thanks for the quick reply. No I didn't check alignment. Yes it got hot. The top of the drive was very hot and the engine was also hot, like water wasn't circulating.

Thanks again...

Sounds like you blew the couple because you didn't align it. The pump is in the outdrive and if it isn't turning them the motor won't get water.

I didn't think I would need to align it because I didn't mess with any adjustments, I only took out the 4 bolts that mount it to the boat. So what coupler are you thinking is bad?

The one on the back of the motor that the drive shaft goes into. The motor has to come out to fix it. Take the drive off and look at it through the gimbal.

Any time you remove the engine or drive, you at least check the alignment just to make sure nothing changed.

The coupler bolts to the flywheel.

Re: Please HelP! with my drive

Well, I'm a idiot. My upper unit is in pieces. Looks like a ran it dry. Didn't check it because I changed the fluid out last year and I've never had it get low before. Man I feel like a dumb ***.

Any idea of cost for repair?

Thanks for the help

Cheapest fix is probably to buy a complete SEI upper drive. You will have to make sure you ALL metal shavings out of lower though.

Re: Please HelP! with my drive

So I could use some more advise. I'm going to buy the upper drive. My question is...Could this have happened from something I did when I pulled the engine or does this type of thing happen from not having enough fluid. I drained the gear oil and thought I would find a lot of metal but there was none. I would guess there was 1 and half quarts that came out, seem like that would be enough to keep things lubed??? I just don't want to have this happen again.

Thanks

Cheapest, but by no means best or most reliable ....you need a whole new drive. Flirting with further disaster otherwise.

Advice on my outdrive replacment

Advice on my outdrive replacment

1993 Bayliner 3.0 Alpha 1 Gen 2

Took the cap off the outdrive and the upper gears are completely shot, I'm assuming because I let it go low on fluid. So a few questions before I order the new upper.

When I drained the fluid there was no metal shavings, not even on the magnet. My lower seems to be functioning properly. Does the fluid from the upper and lower not mix? The upper was full of metal so I assumed there would be lots of shavings in the oil. Does this mean I don't need to worry about shavings in the lower?

Also, is the gear oil pumped to the top while the engine is running or are those upper gears just in a bath of oil? Along with torn up gears and metal everywhere there was no oil in the top.

Thanks

As the oil is drained from top to bottom, the act of opening the plug on the gear housing (you call 'lower') has allowed what metal fragments were contained in the drive-shaft housing (you call 'upper) to drain through and contaminate the gear housing.

When the drive is filled properly the gears in the drive-shaft housing are submerged....

I would recommend you replace the complete drive. Despite there being no metal on the magnet, that gear housing will be contaminated. Just putting a new drive-shaft housing on will see the gear housing fail fairly soon.

Re: Please HelP! with my drive

I am a bit curious as to where the oil "went" from the upper gearcase. Not that it matters at this point, because you are being advised to get a whole new drive, but there is a root cause somewhere here that is undiagnosed. Either it was not filled correctly to start, or you had a seal go bad. If it was the yoke seal, you would have all that oil in the drive bellows area. If it was another seal in the drive there would be evidence elswhere. Me? just for fun I would pressure test the upper and lower separately to see what I had (even though at this point you pretty much have a large paperweight).
