Hey guys! Some of you guys might remember the problem I had about chopping the rope into the cylinder while trying to keep the flywheel stationary:<br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=016876 <br /><br />Well, I should have listened to you more of you guys. Now the piston from that cylinder overheated and MELTED!<br /><br />I got most of the rope out by using a scope and some really sticky tape attached to a coat hanger. Well, I think I either missed some rope in the intake port, or the rings got bent up from the rope chopping. Anyway, it lasted about 20 minutes at an idle, then 10 minutes on the water before the meltdown.<br /><br />So now what? I pulled the head... The head itself is fine. There was some melted piston that I could just flick off. The cylinder is another story. There is a very small crack on one side of it that extends down about 1 inch. The top of the piston is melted. It is locked in the cylinder, but it doesn't appear to be too bad. I am wondering how to get it loose. I didn't want to hit the piston too hard for fear it would expand and be wedged in tighter. I was going to drill a bolt sized hole in the middle of the piston, insert a bolt, and hit with a hammer.<br /><br />Anyway, I figure there is a good chance you guys are going to tell me the block is shot. If so, what are my repair options? The only thing that is really shot is 1 piston and the cylinder wall. Someone told me I could get a 'short block' to replace? Can it be rebored? What are my options?!?!?!<br /><br />Thanks in advance for all of the help! You guys are great!<br /><br />BTW, I tracked down the thread where I got the advice:<br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=002905 <br />Dylan Mitchell did me in!! (although some might say it was my fault ;) )

if you can get the piston out with out pounding.<br />you mite just have to have that cylinder <br />re-sleeved.<br />if you have good material around cylinder.

Well....that's what can happen when trying to make do.<br /><br />If the crack is fron the top of the cylinder, that cylinder is shot. Look for another block or get it resleeved.<br /><br />But you should disassemble the whole thing first and find whats bad and what is not.<br /><br />And get a OEM service manual.

Let me know if you want to sell what's left of that motor - if you're near New England.

Nah, I'm not looking to part it out.<br /><br />The sleeve is cracked from the top. The block metal that surrounds the sleeve is also cracked about an inch. Could this be repaired if it was resleeved?<br /><br />Anyone got a clue how much a resleeving or replacement block would run me in Raleigh, NC? Where should I go about looking? Any boat junkyards around these parts?<br /><br />I'm gonna work on getting the piston out here in a few days. Might know more then. Thanks!

Re: Awww! The chopped rope burned me!

If you have never rebuilt an outboard engine, I would not start with this one. Am I correct that this is a 1994 115 HP. This is going to be an expensive repair no matter how you go. A service manual is a must. but can only take you so far if you have never done the work before.By the way, a repair shop will not look at that tore down engine, and think you done them a favor.
