1989 Force, rings/pistons no good?

[visionspeed]

I have a 1989 Force outboard 125hp and the other day my friend and I went out on the lake for a little while. Well we stopped by the gas station to fill up and he said that he would take care of the oil, well to make a long story short when he said he would take care of the oil he meant buying it and not putting it in. So needless to say I ran an entire tank of gas through the motor with no oil. By the time we were heading back the motor was really starting to dog. We had it at full throttle and were only getting half power at most. Does this sound like the ring and pistons got toasted and need to be replaced? Or shat ideas do you guys have on this? How much wold something like this cost? Any help would be great. Thank you

Not sure how much help this will be! <br />Have you tried to get oil into the motor? I doubt you can do any more harm to the motor now!<br /><br />Remove the plugs and put neat oil in each cylinder, take the air box off and squirt it in through the carbs and turn the motor over with the plugs out.<br />Then do a compression check and see how bad things are. <br />The plugs may give you some indication of what's happened inside especially if you see metal on them.<br />The cost of repair will depend on how bad things are and if you are going to fix it or send it to a shop. If its really bad an exchange or used power head may be the cheapest solution.<br /><br />A similar thing happened to me many years ago and I fried a nearly new motor. I vowed never to leave the oil to anyone except me, it was an expensive lesson!<br /><br />Good luck and hope its not too bad.<br /><br />Peter

Was your gas tank completly empty when you filled it up. It sounds like you must of had at least some gas in the tank that was mixed because I've never heard of anyone running a full tank of gas before the motor started trying to seize up. Mix up a partial tank of gas. Mix it a little richer than 50/1. Pull the hose loose from the motor and flush the straight gas out of it. You can take a small punch or screwdriver and hold the check valve open on the hose and flush it with the primer bulb. Next, drain the carb bowls. Hook the hose back up to the motor and prime the motor. Put the muffs on it and run it for a several minutes. Kill the engine and do a compression test on it. If the compression looks ok take it back to the lake and try it. You may luck up.

Hey thanks you guys for your help. I will give that stuff a try, and hope that it works! Yeah I had a partial tank of gas in there and then ran the new gas through there. Although I did have to fill almost the whole tank. <br />Thanks again for all the help.

I just picked up my 1989 Force 125 from the shop today. Rebuilt and replaced all 4 cylinders and other misc. items. Total bill was $2200.00. I wish you well and hopfully you won't have to do the same.

Well I figured out that it is loosing compression in the #3 cylinder. Does anyone know how easy or hard it would be to replace that piston?

visionspeed,<br /><br />Did you figure out how much damage was done with running lean fuel? I have a 92 70hp force, and had the same problem, let a friend borrowed it and ran it with out oil. I too am loosing compression in the #3 cylinder. I took the head off and it looks ok except when I felt the cylinder wall #2 and #3 didn't feel as smooth as the #1 did. <br /><br />Thanks,
