Evinrude 9.9 HP 4 Stroke Fuel & Oil Pressure Test

[@robertkeaney7047]

Literally just finished watching your last video!

[@BrandonsGarage]

Hope you enjoyed it!

That fuel pressure gauge i must copy in my outboard kit. 7:40 -> Do i hear too large valve gap or spark plug wire grounding? ...aaand as i was writing this the video got to the sparking

[@BrandonsGarage]

Thats funny! I heard it too in the first video, just couldn't find it. Pressure gauge parts I got on Amazon: 1/8" to 1/4" fitting amzn.to/3PsdLHO 0-60 gauge amzn.to/3Pse3yo 1/4" Male to Female Pipe amzn.to/47XWBJc

@@BrandonsGarage T. Hanks! For the parts list for the gauge. Ears are the most common diagnostic tool of a seasoned mechanic.

[@BrandonsGarage]

I know! It sounded like it had oil pressure, so I didnt check it the first time out.

[@ripperace]

I was going to say, “hey, that things arching somewhere” before you showed it. I could hear it over the video. Those double bound coils from OMC seemed to be particularly famous for external leaks. Try the CDI branded units for future reference. I’ve had very little issue with their packs or coils.

I carry a little length of rope just in case that happens to my old 4 horse Johnson.

[@-Viceroy-]

Are you saying you don't change the pull rope in every 40 years?

[@dougaranda6187]

@@-Viceroy- Just insurance. That recoil is almost 50 years old.

[@BrandonsGarage]

Then you also have to carry tools in order to remove the pull starter. Which I don't care too when I can row back.

[@wmkess]

@@BrandonsGarageI really don’t like the recoil starter on the 80s model omc 9.9/15s but I do appreciate the fact that the flywheel and the rope notches are accessible.

Hola hola,,, tengo un motor igual a ese y tiene una falla y quería saber si ajustando el tornillo de aire lo resuelvo,, sabes como ajustarlo? Gracias

[@philstewart9891]

Not sure if it's important but a noticeable leak of some sort of fluid that appears in the gear selector rod connection ? right under the "block" from the handle side looking straight on from the side...camera...liking the diagnostic findings

[@lakeside5137]

I saw it as well. around the 7 minute mark on your video.

[@davidboscaljon3787]

another great video! I like how you trouble shoot things. I like doing the same thing. Have you had any luck finding a hydraulic diagram for a tilt and trim unit 1986 90hp Evinrude? I would like det this probem resolved.

[@BrandonsGarage]

Oh yeah! Did you email me?

[@ripperace]

Brandon, if you don’t have the diagram the fellow needs, I have a copy I can send him.

I have this same motor and it runs for 10-15min then act like it’s running out of gas, but i put in a new fuel pump and rebuilt the carb, still same thing, then I replaced the the water impeller and thermostat and tale tale hose and it pumps water better now but still dies, the only time it never died was when it was 35-40degrees out it ran perfect never failed for hours. So I thought it is heat temp related, so I keep freeze spray in the boat and during summer it ran 10 mins and I let it get to the point it was gonna die, then I sprayed the cdi and it started going like crazy perfect again, I did that 5-6 times, every time it’s ran perfect when I froze the cdi! So I bought a brand new Evinrude cdi and put it on and god damn it did the same thing!! I’m an electronic technician by trade and I can’t believe it still did it after replacing it!! Any ideas?

[@roverer109]

how about providing a part number for that hot cam....

[@BrandonsGarage]

My favorite part of the video.

[@coastalcleaningandmaintena2884]

I went and looked at one of these and yes there is barely any info on them. The code for the short shaft etc just said gv and that meant special gearbox? So a explanation of that would be nice. I know it was long as hell also Didnt show compression. Very tough to find solid info. And i had the plate with the codes and vin stamp etc. Still nothing.

[@johnpozerski7949]

I’ve got a 1978 Evinrude 35 HP outboard but am missing the linkage that goes from the engine to the steering cable. Do you know where I could find one?

[@geesss8675]

So did it run more powerful and faster with the coil? That was not failing?

[@BrandonsGarage]

No, same thing. But it ran smoother and started easier. When we get into the 8 HP 4-Stroke videos that gets explained.

[@rafjaf2567]

Seems its running on one cylinder not two.

[@BrandonsGarage]

oh?

[@vinhoi69]

could you tell me the model of the zip-tie gun that you are using please? Thanks

[@BrandonsGarage]

That is the best darn zip tie gun you'll ever use. It is Evinrude part number 509786. Be warned, opening the eBay link may be shocking and hazardous to some - ebay.us/5SSsbQ

[@coastalcleaningandmaintena2884]

@@BrandonsGarage dam i was ask same thing

[@mattd8668]

I opened the link and pooped my pants a little

[@BrandonsGarage]

@@mattd8668 Its such a pleasure to use though. The way it fit and feels in your hand, the way it perfectly tightens the tie, how it trims the end and leaves no sharp edges, the weight and strength - Just a great tool.

Hello everyone, my 1986 Johnson 120hp v4 looper engine has a on going wot miss or a intermittent miss around 4k rpm. It will only intermittently start missing at around 4k rpm and a constant miss at wot. I have it narrowed down to a electrical issue. I have a 2 year old cdi power pack on it and one new coil and plug wire the other 3 are old. I am planning on installing all new coils and sp wires. But if that doesn't fix it my other option is to replace the stator and timer base which is pretty costly. Does anyone know how the stator and timer base affect the power pack or is there any good way of testing them? Thanks to all for any assistance with this pickle.

If u own a boat and dont have rabbit ears or a barrel your not a real boat owner

[@BrandonsGarage]

You can't take it to 4000rpm without a load on it, it'll over Rev too quickly.

[@coastalcleaningandmaintena2884]

@@BrandonsGarage yes most motors im finding out (cause i wanna buy a boat again) the little fellas wont rev at all in gear. Some do , some dont. In neutral some wont let u get over 2000rpm. Learned alot from you rho bro nice work. Make it look so easy and im red seal certified car tech
