1997 200hp Ocean Runner

[Danobear]

Hi<br />I have a 200hp ocean runner with aprx. 350hrs. that smokes alot when I first start it & extreamly cold blooded<br /><br />After I let it warm up it will die when I put it in gear & accelerate & does the same thing out on the water idles fine & put it in gear & accelerate & it dies & I have to restart & hope it will take off.<br /><br />The compression was fine 2 yrs ago when I bought the boat & I have about 40hrs on it since. I will recheck.<br /><br />It seems to smoke alot too when I am motoring back in the marina after a good run back in.<br /><br />The choke is working properly I hold the key down & count to 8 & it will fire I pump the primer bulb & it gets hard. It has Champion 5939 {QL78YC} plugs & a Racor primary filter with no water in it.<br /><br /> I am going to start over with fresh gas I winterized it with Stabil the last two years. I plan on putting in a water pump also. I have bought the factory OMC manual & would appreciate some Ideas on were to start.<br /> Thanks Dan

welcome to iboats,<br /><br />Im not an expert or evan novice, I do have alot of experience in 2 stroke engines, but not outboards.<br /><br />Depending on how your motor has been run, it could be time for a rebuild. If i were you i would definately warm the motor up and do a compression check on all 6. Make sure all plugs are firing good. From there i would narrow down the problems, It could be a fuel delivery issue.<br />It could be an oil injection issue. <br />Like i said, im just throwing my 2 cents in.. which really are worthless <br /><br />I dont have alot of "expert" answers for you, but would like too comment that this forum is very addicting, you will get serval opinions from more pro's then any marina can provide..<br /><br />Once agan welcome

Welcome!!<br /><br />Are you saying the fuel is 2 years old?

Re: 1997 200hp Ocean Runner

Good morning<br />I fuel up every time I take the boat out so the fuel gets 20+ gal every time out. the tank is 106 gal & its had 140 gals the last 2 yrs added to it. The Racor didnt have any water in last fall when I put the boat away. When I winterize I add Stabil & have the tank full for storage to prevent condensation. I am going to pump out the fuel & run it in my Blazer & start fresh with the boat.<br /><br />The symtoms are simmilar to the ones that Jon Yarr has posted I put it in gear & go to accelerate & it stalls & dies. <br /><br />Its hard to start when its cold also & smokes. After a day on the water motoring back in to the slip it will have a white cloud behind it also just not as severe as when its cold. The previous owner said he had problems with the carbs when it was new & put kits in them & said the gaskets were leaking.

Re: 1997 200hp Ocean Runner

What year is the Engine?<br />Is it set up with VRO unit?<br />If it is... check for leaks in the fuel system lines and oil lines. sounds like the unit may be over oiling and fouling the plugs.

Re: 1997 200hp Ocean Runner

I am getting closer I pumped all the fuel out & removed the lower unit & water pump last night. I checked the recirculation valves & have one leaking on the lower cyl. on the right side & the inline valve is leaking also. <br /><br />I will post the results when I get it running.

Re: 1997 200hp Ocean Runner

Good idea on the fresh fuel. Here's another thought -- if you only put about 20 hrs a year on it, we could be looking at some plugged passages in the carbs or throttle bodies. Things tend to gum up with that little use. Just a thought.

Re: 1997 200hp Ocean Runner

I ordered the recirculation valves this afternoon & they gave me some OMC fuel system cleaner. Should I try this first or just plan on going through the carbs.<br />Thanks

 

[budsbud66]

Re: 1997 200hp Ocean Runner

did you recheck the compression on all the cylinders?<br /><br />A good carb clean is never a bad idea.. but you should do things one at at time...<br /><br />Oh and if you think you had bad gas, odds are the carbs will have tarnish in them.. but In my opinion i dont think gas gets too bad over winter.. it takes a few years to get gummy gas.

Re: 1997 200hp Ocean Runner

I will check the compresion next week when I get the valves in & the lower unit back on. The upper shift rod boot was deteriated & I ordered a new one.<br />I have been gapping the plugs at .030 & see that some are gapping at .040 will this help?

Re: 1997 200hp Ocean Runner

Is yours a Quick Start system? When you mentioned cold blooded, does that mean that you are not reaching normal operating temperature? Just trying to understand better, thanks.

Re: 1997 200hp Ocean Runner

Im not sure on the Quick Start. I dont here it idle up & come down when its warm. I am going to check the temp with my infared temp gun when I get it running.<br /><br /> It smokes like crazy when it starts cold & dies a few times. & after it been warmed up when I put it in gear & throtle up to move it dies also

Re: 1997 200hp Ocean Runner

I think that the recirculation check valves will make a big difference. After that you may want to look again at the cooling/thermostat system.<br /><br />BTW, a couple of gasoline dealers here told me that you have to put the stabilizer in when you buy the gas and that two months later would not work nearly as well. Maybe someone more qualified can confirm that for everyone.

Re: 1997 200hp Ocean Runner

Bad news tonight. I just got the sift rod boot & was getting ready to install the lower unit. I cleaned up the water tube & it felt like it had a hole it the side. Sure enough cancer right were the groment seals around it.<br /><br />I read the manual & it looks like I have quite a project to do. Is there anything else I need to look at when I have the powerhead off. I am going to do the carbs since they will be right in front of me on the bench.<br /><br />Thanks in advance

Re: 1997 200hp Ocean Runner

Hi <br />I was able to repair the water tube with some JB weld it turned out good. I got the motor running & used my Infared temp gun on it it was 104 deg. before the neighbors made me shut it off because of smoke.<br /><br />The compression was 85lbs. on all cyls. & it seems to miss when I throtle it up & all the plugs are wet. I held the plugs away from the headbolt & did a spark test & they jump spark 1/2 in. except #3 port & #1 starboard witch are weaker & almost have to be grounded to the headbolt.<br />Need help <br />Thanks in advance

Re: 1997 200hp Ocean Runner

Did you check the compression with all plugs out?<br /><br />Temperature is not hot enough - new thermostats & seats?<br /><br />Unless you get that temperature to proper operating temp, you won't burn off as much excess oil, you will keep getting more carbon than you otherwise would, and the motor will not run as well as it could.<br /><br />Also, if it were my call, I would replace the ignition coils and plug wires on 1 & 3. Part 582508. I think the wire is 582365, but check it.

Re: 1997 200hp Ocean Runner

All the plugs were out. I didnt do the T Stats yet I wanted to get it running. & check things out. Is there any way to test the coils with my Fluke meter? I will try moving them & see if the spark changes. <br />I will post the new results<br />Thanks

Re: 1997 200hp Ocean Runner

Disconnect and clean all the wires and check again.<br /><br />Sorry, I have never actually tested coils. There is diagnostic information on the troubleshooting download at Rapair.com. <br /><br />Bad coils can kill a powerpack and wreck a fishing trip so I just toss them if cleaning and tightening doesn't fix it. Same with the spark plug wires. Those coils are $15 - $30 each. <br /><br />See: TroubleshootingGuide<br /><br /><br />It is 65 pdf pages, be patient. But save it on your computer, it's nice to have around even if you don't print it out.<br /><br />BTW, I don't want to give you a hard time, but you really ought to fix the thermostats now. A lot of your problems will lessen once you do. I am pretty sure your motor is a looper and they don't like cold. It's a 10 minute job if the screws are ok.

Re: 1997 200hp Ocean Runner

Thanks<br />I went out after work tonight & ohm tested the stator & timer base like the book said & it was within spec. I also moved one of the known weak coils & it it tested the same in a diferent spot & the strong one tested good in its spot I will order two tomarrow & T Stats for it two. <br /><br />More news to come. It takes my dealer about a week on parts

Re: 1997 200hp Ocean Runner

I did a water test tonight. It started right up & less smoke. After warm up it has a miss on one cyl. at idle & when I throtle it up it goes away & runs fine top end is nice & smooth it sure like to get up & run.<br /><br /> When I motored back in to the marina there was no smoke but it has a miss at idle & the engine shakes. <br /><br />I replaced the T Stats & I heard the Quick start work & idle back down after it got running.<br /><br />Need more help. <br />Thanks
