locked up?

[outcast]

I recently purchased a 1987 ebbtide with a "470" alpha 1 outdrive,this boat i got for a steel,he told me the motor was just rebuilt but when he took it in to have the gauges worked on after his test run that didnt go so well due to the wires catchin cause of the crappy alternator set up,that has been fixed,the people there told him the motor was locked up?i took the boat did the soak w/pb blaster ect,and stil nothing,took the starer off...nothing...so i pulled the head and found that this motor was so clean u could eat off it?there was water in the back cylinder?alot like 2in?there was also what looked like mud around the area? so i cleaned it soaked it again and staring to try and work it free,it statred moving a very little,i them took the outdrive and proceded to keep trying to free the motor,then it came free and spins nice now? is there something in the outdrive that would cause the motor to seemed locked up when puttin a socket on the crank?why would they say the motors locked up?everything in the oudrive looks new and he tells me it is?why when i pulled the outdrive i could turn the motor? or did that just help me free it up?is there something i need to know before i put it back together?like when i install the outdrive is it going to not let the motor spin over?

thanks alot guys all the info i can get is very helpful

and i only paid 200 dollars for the whole thing it looks brand new the trailers worth that to me lol i hear the 470 is a piece

Re: locked up?

also is it possible he blew the head gasket thats my first thought?none of the gauges are working he says?why he ran it with no gauges i dont know my guts telln me he didnt install a new water pump and he overheated it,and being its a closed system water backflowed back up to cool the engine to cool it and blew the gasket? but im not a mechanic

thanks guys

Re: locked up?

When the drive was on the boat did you make sure it was in nuetral? Isf so try turning the splined shaft of the drive now and see if it turns. You can turn the shift shoe on the drive and put it into gear hold pressure against the prop and sping it in gear and see if the prop turns to.

Re: locked up?

Even if it was in gear you should have been able to turn the prop too but it's more resistance, Still check the drive for rotation.

Re: locked up?

when the drive was on the boat i spun the prop in neutral it spun freely,i put into gear and it spun freely makig a clicking noise,but the derive was all the way up so im assuming the shaft was binded thats why it was clicking did the same in reverse whil it was on the boat.why would there be water in the cylinders?can the outdrive bind up and make the motor seem like its locked up?

thanks again

can the outdrive bind up and make the motor seem like its locked up?

Yes...

Re: locked up?

when the drive is in gear and you turn the prop by hand, it will "lock" one direction and spin, but click, the other direction - normal.

Re: locked up?

okay..i pulled the outdrive apart to find the upper bearing (under top cover w4bolts)and found all 12 of the bearings...it was completly destroyed...Ive come to conclusion that the drive was locked down...the main bearing that connects to the shaft and knucle joints i still in place but frozen..soaking them now...the lower berings look good well..going to replace all of it seals and all...except gears and lower bearings...i believe this to be the culprit..

also i pulled the head off to see why it seemed locked down(before i pulled outdrive) my father in law pointed out today that it seemed far to clean,we started digging deeper,and i pulled the distributor the gears also was ate up?
the was no oil in the top at all....so measured the shaft and it about 3/4in short of the oil pump? i then put the shaft on a long ext and spun the oil pump and oil came up...im now thinking this may have caused the blown head gasket? Im so glad in the case i started at the motor,being i found multiple problems inside and out..Nex steps are
-replace bearings in the outdrive
-replace seals and gaskets outdrive
-install new water pump
-replace head gasket & gasket around heat exchanger
-distrbutor cap,button,gear,longer shaft,
-cam gear
i hope im headed in the right direction

thanks alot guys il keep updating untill i get her running
ordering parts now

Re: locked up?

is there anything else i should be checkin since i have the motor torn down?
can i get to the cam gear from front of the motor,looks like its behind a water pump?has a hose going into a 6 bolt housing?

again i have only pennies in this boat and its super clean dont mind spending some money to get it running,it was rebuilt its to clean and everthing is still numbered,i think it was operater error..the gauges dont work and i bet he over heated it and the oil pump shaft wasnt pmping like it should,i removed the mech.fuel pump and can see the cam and the bearing and it looks good and oily?I was told theres one hour on this rebuild..also all the updates are done too,new after market alternator(for the bad charging system on th 470)
and has a new 4in heat exchanger

Re: locked up?

I was told theres one hour on this rebuild..

Ayuh,... Your story isn't really adding up,...
An Hour's run time with the oil pump Not turning, the bearings should have Siezed Solid....

Considering you're only into this thing for $200....
You could part it out,+ take the Cash to buy a Runnin' boat...

If the upper is destroyed, so is the lower. Where do you think all those shards shavings and chips end up?

The special tools required to rebuild a drive are very expensive. The knowledge, skill and experience are not something you get from holding a manual in front of you while you wrench away.
The cost to have someone with the tools and experience rebuild your drive is far beyoung what a new SEI drive costs

You need another outdrive, yours is junk and staying that way.

also i pulled the head off to see why it seemed locked down(before i pulled outdrive) my father in law pointed out today that it seemed far to clean,we started digging deeper,and i pulled the distributor the gears also was ate up?
the was no oil in the top at all....so measured the shaft and it about 3/4in short of the oil pump? i then put the shaft on a long ext and spun the oil pump and oil came up...im now thinking this may have caused the blown head gasket? Im so glad in the case i started at the motor,being i found multiple problems inside and out.

That engine wasn't ever rebuilt, it may of had some random parts hung on it by some hack, but that is not a rebuild.
I seriously doubt that thing ever ran after it was screwed with.
You have somehow invented a crazy blown head gasket scenario that makes no sense at all. You don't even know if it does, evidently you didn't look at the gasket when you yanked engine apart.
There is no reason to be glad about anything here.....it's a very questionable engine with a junk outdrive

.i hope im headed in the right direction

Parts boat.
Sell what you can and find something that at least has a hope. You would be in that thing 2 Grand and still may not have a boat that moves under it's own power.

Re: locked up?

hmmm...i never said i was a mechanic thats why im askin these questions...and the outdrive isnt junk my uncle just left here (35yr exp marine mechanic) and pulled the lower drive its fine just need new bearings? so why do u say its junk? its alpha one ss?he says it the best outdrive mercruiser produced?as for the motor i was wrong on the distributor and the impeller in the lower was no good caused a over heat and a blown gasket...the motor is fine he says we just finished putting it back together other than the head gasket that wont be here till wednesday,Il bet u by friday itl be running so whay would i junk it? al together its cost me about 700 bucks.....the trailer alone is worth that....pls i didnt ask if i should sel lit i ask for advice on trouble shooting...so pls if your going to say its a piece and i shoild sell id prefrer you wouldnt respond....and everybody says i got a hell of a deal on it...its a 87 ebbtide looks like it just cameof the show room floor...i have a 2007 24' grady thats not in as good as shape this boat is....and im a clean freak....he also is a member here and says half the ppl on here arent mechanics and dont know ****...although he said bondo was knowlegable...

Re: locked up?

Ask your uncle it would be alot easier then getting a answer here i have noticed some negative posters here and they know who they are but you can find good answers here, but if you have a uncle that is a mech use him.
