Doctor we have a problem

I guess using the old gasket and a head from a different engine block was not such a good idea.

Ah, the old 'ventliated crank case'. Hydrolocked it?

 

[nabiul]

I don't know what happened, my guess is the head gasket leaked. The motor ran fine in a bucket but out in the water it ran for like 30 seconds, I was at full throttle and it felt like it was producing half power then a sudden pop and steam came out from under the lid.

What do you guys think? Do not resuscitate?

I don't know how the bearings managed to fuse together like that. Maybe this was more than just water leaking into the cylinders, maybe I assembled the bearing wrong?

What oil and what ratio were you using? Heads and gaskets are hard to blame for a rod failure

 

[nabiul]

Castrol super outboard motor oil @ 50:1.

I think I assembled it wrong, I had difficulty getting those sheet metal bearing parts to match. I'm also just now finding out that johnson marked matching rods and caps; I think I mixed up the 4 pairs I had.

What year and HP?

The Block is blue, that leans toward Evinrude

Sheet metal bearing parts? Did this engine have needle and roller bearings on the crank and rods?

 

[nabiul]

It's a johnnyrude 9.5, evinrude block, johnson cylinder head, mid and lower unit. Pointless trying to determine the year.

You can see the bearings here: http://i.imgur.com/n88xSlk.jpg

all 9.5 used 50:1. The pic is worth a thousand words. The bearing wasn't able to move. Mismatch of parts or incorrect assembly

I just got a really stupid idea; this power head is dead no matter how you look at it, I will have to throw it out any ways, so why not try and make it work again. I have a crank case cover from another head, I can punch out the alignment pins and try to manually align it. I have extra needle bearings, sleeves and piston rods.

I'm thinking I should be able to get one or two uses at low power before the ruined journal grinds to a halt again.

Cover and block are a matched set.

Sometimes this is as much fun as reading the comic books.--Sorry.

 

[nabiul]

Cover and block are a matched set.

Yeah.. I just put everything to the curb. This motor was a bad deal from day one, never ran properly even before I opened it up, but a good learning experience. Next time I will test before buying instead of meeting in a mcdonalds parking lot.
