Engine Trouble

SIDEBAR-

The Towboat US guy was driving an 80's 250 sportsman and I fell in love. So maybe a whole new rig is in the works.... ;)

I would look around a bit. You can find REALLY late model 2 stroke carb motors for under $4K in the 200/225 range. The 150/175 EAGLE motors are known as OMC's BEST engine ever, so that is a BIG reason for them holding there value so well. The only way to know for certain that you are getting oil is to ditch the VRO and pre-mix.
 
i love yammies, but if i was you i go for the other 2000 omc if its a good deal.
this way you have all the parts you will ever need. and easy repower as all controlls and stuff already there.​
 
here's what ya need

http://wilmington.craigslist.org/boa/976388019.html

1997 Evinrude Ocean Pro with less than 200 hours. Excellent condition with no rust. Compression even on all cylinders. Engine is 25 inch shaft with standard rotation. Recent lower unit oil change and New Tilt and Trim Motor.

Extremely clean and sound engine. You will not find one like this anywhere.
Engine only. No prop or controls. I can assist in getting wiring harness and cables. Engine hood is Johnson as the Evinrude hood was stolen off my boat.

$2850

I have already been talking to that guy. He sold that engine but has another 97 that he is getting rid of. I was going to get some pics of it before I headed down his way.

I have been scowering Craigslist, ebay, THT, etc looking, hopefully I can find what I need.

Sorry to hear about you troubles. Try Ron's Marine (Johnson/Evinrude). I get all my work done there.

Quickest way there:

Out of Suffolk 58 to 264
Exit Victory Blvd, turn left
At third light, Airline Blvd turn right
Continue on Airline until you get to Mosberth Resturant right hand side of street.
Turn right on Rodman Ave.
Go through the second or third stop light. (If it's green) :-)
He is on the right hand side of the street, blue building

If you just get off at the Portsmouth BLVD exit (only exit and direction you can go) and then just go dowm a mile and turn right on Rodman and they are on your right. Just an easier way to go.
 
Well here is an interesting twist...

Just spoke with Ron's and he doesn't think it was completely an oil issue. He said the VRO mixes the gas and oil before sending it to the carbs so if one carb/one cylinder got low oil they all would, which doesn't seem like its the case as I have only one bad hole. He said it may be a carb issue that reduced the fuel/oil mix to #6 and eventually fried it.

no it was oil issue not a carb, ive lost several when the vro stops you usually only loose the last cylinder in the fuel feed for some reason. some times if it happens fast you can loose the first to get the raw fuel. but that is normal to loose only one cylinder they are only wanting to do a complete rebuild and carb job.
 
But why then is there no evidence of an issue in the other cylinders? I have good compression on the other five and the top two on the right looked clean when I pulled the head. The two things that I don't get is that it was only a short burst of no oil, I mean short, and that only one cylinder went and the others are perfect.

The reason is simple, You stopped running it before the other cylinders had a chance to destroyed themselves.
 
The damage normally only happens to one like SKOOLS said. I have a YAMAHA 250 that COMPLETELY lost one cylinder, yet it still ran on the other 5 and they didn't look that bad. It just proves that these engines run on a FINE line of just enough oil to live on with the VRO. If it leans out just a little, you can't predict what will happen. That fractional drop in oil though could have been just enough to finish that cylinder off, while the others escaped. If you think otherwise, look at how many MERCURY's have died on just one cylinder from the crank gear just beginning to slip.
 
Figured these pics are appropriate to this topic. This engine was on a boat that I bought awhile back. It was a 93 MERCURY XR6 150 with the oil injection removed. The person I bought this from was 17 and had never had a 2 stroke before. The guy he bought it from told him he should double up the oil for the first tank, so he mixed it 100:1 instead of 25:1 like he was told. The other 5 cylinders were fine with 125 compression, but #2 was a DISASTER! And this was on pre-mix so no oil injection to blame, and the carbs were in tip top shape.

Stillrunning,
Thanks for the heads up. Called them and they are fresh out of any johnrudes that would work.
