1983 Evinrude 60hp multiple probs

[sailor_turned_stinkpotter]

I bought a 60hp 2 cylinder model non-running from an old retired welder. I mention welder because it is a signal of things to come in this post....<br />The engine was cheap enough...300 NZ which is about 150 american, the prop alone is worth almost that and the bottom was fine as far as i could see.<br />So after cranking it over for about ten minutes there was substantial water on the bottom cylinder which had 100psi and the top cylinder was a disaster at 30psi.<br />Pulled the head to see what was going on. Well, this retired old welder had welded in numerous, about 8, little brass or some kind of metal tabs around the top of the cylinder sleeves joining them to the top of the block.<br />I called him up to find out why, and he said the original engine design only had one tab on the top cylinder and it had worked loose, so when he welded the one original tab back in he went welding-crazy and decided to weld in some more on the other cylinder too.<br />The head gasket was fine since he did a meticulous job flattening his work so I proceeded to tear the engine down to the needle rollers to find out what else was wrong.<br />After pulling the power head off lower, I found large crack on exhaust port into bottom cylinder, hence the large amount of water into bottom cylinder. I took the block to engine recond. shop and they reported top cylinder out of round by 14 thou, the reason why no compression. So I will bore out both cylinders 30 thou put new pistons and rings, and weld the crack on the base and then square the head, the block, and base which means I should have a new engine if I manage to put it back together properly.<br />My question is will all the little metal tabs welded to the top of the cylinders restrict or hamper the water flow in the engine or cause any other sort of problems? The recond shop do mostly car motors but thought it wouldn't hurt the outboard engine but.....<br />Also, this is the first time I've taken an outboard apart this far, is there anything else that is recommended to be changed while I've got it all in little pieces?<br />Sorry for the long post, but I just thought this engines probs might help someone diagnose their own engine some day....<br />thanks in advance.

Cinsidering the problems with this motor I would think long and hard before investing what seems to me a lot of money and time In a motor you dant even know if it will run.Did it have spark?<br /> Does the fuel system seem to work? You should go through the lower unit and water pump before investing to much money in the power head.<br /> If the lower unit needs parts it could add up fast. Just a thought from a conservitive old fart.

HI Steelespike<br />There was tons of spark, and plenty of fuel was going through the system.<br />As for the bottom end, without tearing it apart too, I'm just taking the old welder at his word. He says the whole motor ran fine until it bogged down on him one day and then wouldn't start. I'm sure the reason was the crack in the bottom cylinder exhaust port which let in all the water and when he pulled the head I think he may have assumed it was the little metal tab which was letting water through the head gasket and then went welding-nuts. And then when his motor still wouldn't start since he actually added another problem by warping the top cylinder, he gave up and bought a brand new Suzuki 50hp.<br />He's been completely honest about everything so far, so I know its a bit of a gamble, but if everything works out I"m getting a brand new motor for a fairly cheap price and not really too much work since I enjoy working on these outboards. The pistons were $150 each including rings new zealand dollars, and the machine shop fee totalled $160 for the bore and squaring. The new gaskets were $60. That means so far under $700 nz dollars. These motors sell on the local market for about $2,500 used and $4,500 if completely rebuilt, so it's actually an invest if I resell it instead of keeping it. I'm definitely going to keep it for the time being though, but I think you know what I mean.<br />Any thoughts on all the metal tabs at the top of the cylinders?
