35 hp evinrude

[Seascout3]

I am trying to help a friend out of state. He acquired a small boat with a 35 Evinrude. The id tag is completely unreadable. He was going to mix up a tank of gas and he noticed an oil tank under the cowling. Does this give a clue to the year and model? And is this some kind of VRO system so he doesn't have to premix gas? Thanks for any help.

Study that unreadable model number, also look on the powerhead for a small quarter size core plug (looks like a small freeze out plug) that may have the same model number imprinted upon it.

Other than having that model number, we'll need an assortment of good quality pictures to determine what you have.

It sounds like a 3 cyl built around '96 to '98 which did have an oiling system on them.

Re: 35 hp evinrude

Still trying to long range diagnose friends 35 evinrude. I got some pictures emailed to me but I am not good at attaching files. I will work on that. He tells me it will start right up with the choke on. Let run a while and push choke off, 30 seconds later it will start to die. Can keep running by working the choke. I asked him to squeeze the bulb. Have to wait and see what that does. It has new gas. Also told him to see if the bulb collapses. It sounds like it is fuel starved. Anything to check? How to verify fuel pump operation? Thanks

Trying tto add pictures. Hope someone can guess the year.

Re: 35 hp evinrude

In image 009, the plastic intake cover has a knob in the middle of it. Is that an adjustment or is it just what holds the cover on. If I was where the boat was I would get a manual for it. Doing long range diagnosis is hard, but I appreciate any help.

Re: 35 hp evinrude

The pictures aren't that clear, but can anyone guess the year and model? 35 hp with VRO.

I think that is is mid or late 90s but I am just guessing based upon the decals.

Re: 35 hp evinrude

you need to get your friend to take a penlight and have a good look on the powerhead for a welch plug with the model #stamped on it. it could be hidden behind the coils etc etc. the knob on the oil tank is the vent to allow air in so oil can get out.

Re: 35 hp evinrude

Latest update. Pumping the bulb does not affect the engine. It will slowly die after starting. Sounds like the other thread on here about a 40 hp. The carbs supposedly have been redone and have only about 9 hours on it since. Don't know how long it sat since though. Plugs look fairly dry. I am sure it must be a fuel starvation problem. If he can't find the porblem, he is taking it to a shop Friday. Hate for him to do that because I am sure it is something simple.

Re: 35 hp evinrude

has he tried a known to be good tank? i had a 25 johnson from roughly the same era, and the pick up in the plastic tank rotted, allowing the motor to suck air, pumping the bulb was no help.as a last resort/test i took the connector off the tank end of the fuel line and put the line directly into the fuel.....bingo, ran like a champ.

Re: 35 hp evinrude

Tried to post once. I will try again. Took to shop. Tried another tank and hose. No help. They took the gas hose fitting off the engine and pulled it from the hose. There was some kind of plastic grommet around the hose barb that was broken in several pieces. They think some of the plastic pieces got in the carbs. Next step is to take the carbs apart. Shame because they were recently rebuilt. They also suggest doing away with the VRO and premix so you don't have to worry about if it is working right or not. Will report on the final outcome.

Re: 35 hp evinrude

The engine is a 1996 35. Get rid off the oil injection it is known to fail. Run 50:1 pre-mix. There should have been a fuel filter before the carbs that should have prevented anything getting into them. However a complete cleaning won't hurt. The engine has two fuel pumps and with the oil injection removed will deliver plenty of fuel even if one pump is bad.

HideF,

Good call. they have identified it as a 1996 35hp model E35RMLEUR. Now that you mention it the motors I have had all had a small inline filter just before the pump or carbs. Cheap protection that would have prevented this. Still have to wait and see what the carbs look like.

Re: 35 hp evinrude

Shop said the carbs were pretty gummed up and engine is running good now. Can't rely on what people tell you and sometimes you just need to start from scratch. New problem though is they say it is not cooling properly. Needs a new thermostat assembly. I am going to start a new thread on that issue. Thanks for all the help.
