Re: VRO delete 150 oceanpro

while I dont currently have a motor that mixes the oil with the fuel pump, I didnt choose that....but I would add it is like so much else on an outboard...you have to maintain it and monitor it. low oil will sureing cause more friction which will cause more heat....if you are watching your temp gauges( yes GAUGES) you will know the temp in each head and be able to shut off your motor before it gets to 220 degrees!! it cant be worse than a dirty carb which is sucking all the air it can even though the needle is dirty and letting way less gas through than it should....your temps should rise....as it leans out....same goes for a water pressure gauge...with out one...how do you know when your water pressure isnt sufficient to keep your motor cool at 5000 rpms??? motors go bad...its the luck of the draw sometimes.. but the more you pay attention, the longer it will last....how often does everyone decarb their motor??? i am trying to get it done once a year now...because i use the extra oil in the winter (nov-feb)....hopefully it is working...because i dont usually tear the motor down to look at the rings!!!!!!!!!!

Point taken. Have to take engine temp as pretty much a matter of faith, with proper maintenance and some monitoring. Just would rather not take the oil mix on faith if I can find another way.

Aluminum pistons shrink more than cast iron does when it gets colder.

snowmobiles use oil injection..... has anyone ever heard of a snowmobiler disconnecting the oil injector and mixing his gas????

I don't know if that's a design...issue.....or that boaters break more stuff.....and want to blame something...

Re: VRO delete 150 oceanpro

Actually? Yes. Ran into a couple of snowmobilers in Branchport about a week ago, fueling up when I stopped for gas. He was adding 2-cycle to the tank along with some gasoline anti-freeze. (My old Trojan cruiser is packed away down there until maybe May this year, if the ice melts then.) I talked about boats all secured for the winter. They joked about keeping snowmobiles running in the cold, and the fact that most of their systems freeze up or break in the cold, sooner or later.

I deleted the oil injection on my ski-doo long ago and am very happy,and my last outboard (60 Yamaha) was not oil injected so I am used to if not programed to mix my oil. Fact, if you can control the oil ratio then that's one possible fail eliminated. I want to mix my oil , but it has to be done in a way that makes sense, bottom line,the vro has to pump fuel in a way that's healthy for the whole engine

Your combustion chamber temps should be the same year around if the motor is up to spec.
i would agree with that under normal operation conditions. However, trolling at 800 rpm in 36 degree water temps, 8 hrs at a time is not your typical operation. Thermostats can't deal with it. I've seen engine temps at 120 degrees before. Watch the temp bounce around with the stats opening and closing. Not enough heat to stabilize the temps. Unburnt fuel running out of the exhaust and down the leg at the end of the day. I've seen boats come in with a white frothy oil buildup around the exhaust. Assume it's one of the oil components that solidified Don't know for sure.
Loaded up a bit at the end of the day but no real problems. The 20-25 mile run back to the barn blows it out pretty well.

Any recommendation to get the temps up

I was going to say its in my signature but for some reason my signature is missing
1997 200 evinrude ocean pro. 2200+ hours on first power head. 213 hours on its replacement.

Didn't make any sense. Why mix more oil in the winter where your already running rich and loading up from the low combustion chamber temps.
you have it backwards, colder air in the winter would cause a lean condition, not rich

Lets think about this a minute.....

Lean: - low in combustible component
Rich: - high in combustible component


Correct me if I'm wrong, the terms "rich" and "lean" are relative to the needs /efficiency of the combustion process?

If conditions cause the combustion process to use more or less fuel, don't "value" of rich and lean change with it?

If you reduce the "combustible component" by 5% and the efficiency of the combustion process drops 10%, would there not be a 5% net gain of "combustible component" in the combustion chamber? Would the excess fuel not make the combustion process "high in combustible component? Otherwise, the excess, unburnt running down the leg of the motor after a long cold day of trolling must be because I was running "low in combustible component" all day. :lol:

why didnt you also tell us what color your boat is??? or what way the wind was blowing....or what you had for breakfast....

its settled Dingbat is a trial lawyer:facepalm:

Re: VRO delete 150 oceanpro

Well, wind direction might actually be a factor. He's running in super cold salt water which is corrosive, and at low speeds to boot. Further up the Bay where it's even less salty, some of the fishermen like to pull t.stats in spring or fall because they find that salt water corrosion mucks up their t.stats. Sticky t. stats. That's the answer.

What was the question again? :)

The question was, how does oyster gro go about deleting the oil injection on his 99 ocean pro? Is there any chance someone has something constructive to offer a man in need?

Re: VRO delete 150 oceanpro

Gee, we started off answering that question. His OMS system is a good one. I have the '98 version of that motor and run mine with the OMS intact. It mixes oil at about a 60::1 constant ratio. Obviously the fuel mixture is always fresh, the motor runs real well and I save on oil.

I watch my warning alarms and keep a gallon of oil (I have a 63 G fuel tank) on board.

If he is bound and determined to disconnect the oil injection, there is a sticky that describes how to do it.
