Where to look for outboard model #?

[MRneatfreak]

I just bought a boat that came with a johnson/evinrude. I am not familiar with the engine. I need help with the location of the enine model number. I looked for a data plate but I don't see one. I did however find several casting numbers from various parts. The cowling says Johnson 88 SPL.

Both carbs are 322033
Head 1 & 3 323106 D1
Head 2 & 4 323105 D1
Steering arm 214616
Access Plate at the side of the heads 210532
Power pack has two different numbers on it 9379, 388

Any ideas?

Thanks.

Re: Where to look for outboard model #?

Hello Mrneatfreak. None of those look like model Numbers. The Johnson 88 spl my help some of the experts,but I'm not sure if it will. All that i have seen are on the transom clamp either on the side or dead center in the front. Or sometimes there on the little round plugs. It's probably where you got one of the numbers you posted . Sometimes they'll post a model number under those Numbers. Usually the model numbers will have some combination of numbers and letters. If you can post a pic someone will most likely be able to help you figure it out.

Re: Where to look for outboard model #?

The head part numbers were first used on a 1978 V4 85 hp engine. That year the 85 hp blocks were 92 cubic inches, the 114/140 were 99.6 cubic inches. It's likely someone has changed the cowling over the years. It's not a 88 SPL. They were all 99.6 cubic inch blocks and started to come out in the 1987 model year.

Re: Where to look for outboard model #?

You said 1978 was when they started using those head numbers, what year did they stop? I've pretty much given up on finding the serial and model tag on the engine itself. I have two other evinrudes that have been sitting, and they both have their silver data tags bolted down. I have been buying parts so far for this motor as I think it is around a 1979 model.

Maybe I should post this elsewhere or start a another thread?

That brings me to more questions. If memory serves correctly (I'm at work on lunch) I have a 73 evinrude 135 horse, and a 77 evinrude 135 horse, and my current evinrude which is a 85 horse. The top of all three of the powerheads is for the most part identical. Including the coils, power module, and the layout of the wiring. Is this stuff interchangeable?

I am dealing with a no-start/intermittent light off of the 85 horse. Carbs look good, and match, I removed the top one (322033) took it apart and it was clean inside, and made sure the float was parallel with the carb when upside down. Spark looks good and constant for all four coils.

Here is where I am at:
I suspect either a sheared key, as I would still see spark, but it wouldn't be timed in the right sequence. I have to spray 50:1in a spray bottle into all 4 holes and maybe it will chug for a second, or backfire, but wont stay running on its own.

What I don't know is how to set the basic timing without the engine running. Or even if I need too?

Also is there such a thing as a fuel pump or is it just vacuum suction? Where would I look for a vac port? I am using a little plastic outboard fuel can with the squeeze pump on it (yes it is flowing the correct way). The plugs are sometimes wet if I spray too much, and the electric choke works.

Thanks, for the help.

Re: Where to look for outboard model #?

Look on the top of the block for a quarter sized core plug stamped with the model no. Also, on the port side of mounting bracket there should be a plate with the model and serial nos. I would suggest finding out what you have before jumping into a lot of other stuff. Once you figure that out, I would suggest getting an OEM shop manual.

Re: Where to look for outboard model #?

Further investigation reveals that those part number heads on that engine were only used in 1978. So, it's a 78 powerhead. One additional thing to further identify the block is that core plug mentioned by wilde, in the thread just above this one. Back in this time frame, those aluminum core plugs had both the serial and model numbers stamped clearly on them. That information is identical to what would have been on the missing aluminum transom bracket serial plate.

Re: Where to look for outboard model #?

1978 sounds about right thanks for digging that info up for me. That's the year most of those part numbers lead to on the different brackets on the engine. They are mostly 312XXX and 313XXX numbers.

Ok this is the best I could come up with, I thought I had posted this number last night from the transom bracket 85793S, don't know if its relevant or not. The data plate on the transom bracket also says it will handle up to a 85 horse outboard.

I searched for a freeze plug but didn't see one on the power head?

I'll go get a few pictures and upload them.

Ok here are some pics of the 85 horse.

The freeze plug normally would be on the top aft part of the block, and may be obscured by wiring or hoses.

I answered my own question, google turned up engines on that transom bracket all the way from 1976 to 1983.:facepalm:

Does a regular service manual delve into the complexities of flywheel removal?

Ok I'll go zip the coil bracket off real quick and take a peek.

Found it!

Thanks for the help

Re: Where to look for outboard model #?

See top secret file for flywheel removal details.

Your motor is an 85HP '77

 

[MRneatfreak]

Re: Where to look for outboard model #?

Ok not a 78 but a 77. Great thanks everyone for the help, maybe I can get this baby started by tomorrow?

Re: Where to look for outboard model #?

One more time on the flywheel: see Top Secret File at the top of post list!!!

Also, link is below my name!!!

Re: Where to look for outboard model #?

Yep saw the secret file and went through all the links, especially the flywheel one. I've done flywheels on riding mowers and it looks similiar. I'm curious though if I remove the nut on the crankshaft, will I be able to inspect the groove on the shaft in relation to the flywheel, to see if the two are still aligned? Or will I need to remove the flywheel to see if the key has sheared?

Would a powerpack cause a timing issue, or is its job just to allow power to pass through it if all the right prerequisites are met?

Also what is the purpose of the sensor in cylinder head #3? Is it just to sound an overheat alarm, or will it shut down the engine if overtemps are sensed?

Re: Where to look for outboard model #?

Flywheel must come off to inspect the key . You must torque the nut to the correct value and the tapers must be clean and dry (no oil). You may need a holder to restrain the flywheel when torquing. Like this:

Re: Where to look for outboard model #?

The 77's 85 hp engines all had the single power pack on the back of the engine and the top-mounted coils. In 78 they went to the newer (dual) style power packs which were mounted on the side of the engine and the coils which mounted on the side of the heads. Check the flywheel key. If it is intact, the firing order should be just fine. The fuel pump has a hose which is ported to one of the cylinders on the crankcase. Each revolution, a vacuum pulse is transferred via a hose to the fuel pump. An internal rubber bladder moves to the pulses and pumps fuel. If you think the fuel pump is not functioning, see what happens when you constantly prime the fuel hose bulb and try to start the engine. Good thing the choke works-they are nearly impossible to start without a choke when they are cold.

View attachment 133145

Looks like that tool could come in handy. Most likely alot less damaging than trying to use a screw driver with no leverage. Kind of like trying to torque the flywheel on an old rear wheel drive with an automatic.

Re: Where to look for outboard model #?

I have messed around with the fuel issue quite a bit. I did try pumping on the primer bulb, and also squirting it into the throat of each carb with a spray bottle, but nothing seems to work. I also took the fuel pump apart and inspected the diaghram and the little springs. Nothing was torn, the springs looked ok, along with the little plastic pushrods. There was a little corrosion on some replaceable metal pieces inside, I sprayed em off, and put it back together, still nothing. I did however find it curious that when I removed the fuel line from the pump that feeds the tee fitting that then branches off to the carbs. Well the lower hose was full of gas? This was the carb I didn't take off and inspect. So maybe the pintle valve is stuck in the closed position, not allowing fuel to fill in the bowl?

Next order of business is the flywheel though. If it doesn't pop off right away, then I'll dig into the lower carb.
