How does it do while being pulled kn a trailer?

I guess this piece of junk never got finished?

I have a 1993 20hp and I was going to do the full delete but after looking at my system and yours I might just put all new fuel and oil lines on it. My lines are rock hard and ready to crack. Early 90s Japanese stuff is pretty nice. I can see an argument for both deleting it and leaving at stock. Thanks for the follow up video. I know some people in these comments sections can be brutal. Haha

With proper maintenance this system doesn't usually fail. Oil injected carbs usually have different jet sizes than non injected ones. The oil injected carbs are jet'ed for gas only mixture and when you add oil to the mixture, you change the weight of the fuel. On Yamaha oil injection, the oil is never mixed with the fuel before entering the carbs. That's why Yamahas have less problems with carbs gumming up when they sit. I tried removing the system but I ended up going back to it, I'd rather keep it on than remove it but to each his own.

How can I reach you? What make and model Jon boat is that please?

Nice I got to make me one for that last fishing before ice but I going to use real thin aluminum, how wide is the beam on your boat and how dose it handle in the water?

Bwhind that arm in pump, theres a small round brass cap? Is that removed aswell?

Regardless of the manufacturer , always remove the oil injection as soon as it comes off warranty. The company will not fix your motor if and when the oil injection fails and it will fail(some sooner than others) If the shaft (not being removed) would have caused damage whether or not the tank was removed or not. If the shaft(not being removed) would have failed anyway and seized the motor

How can we see this boat in action on the water? I love it but want to see it so badly!

This is fantastic!

La

Thanks for posting this I have a 40 hp Evinrude that I believe has the same issue. You made it look easy compared to what I thought it would be!

Nice ride! 👍😎

Glad to see you were able to salvage your tarp. That is a nice boat you have there and you need to protect it. I have a similar arrangement for my boat an 18'-0" Starcraft center console with a 70 H.P. Johnson. My Cover It shelter is the Gambrel roof style 12'-0" x 24'-0" x 11'-0" high with ratchet straps to hold and tighten the cover. The boat weathers great in it and I even have basic electric lighting in it so I can do boat maintenance in bad weather. I did a complete overhaul of the boat in 2018 with new plywood decking and new marine carpet as well as a complete paint job inside and out by spray gun ( all aluminum boat ) and I want to take care of it now that it is complete. Good luck with all your projects !

Why would you even do that Yamaha is a world's difference from Johnson evinrude smh ruined that engine I have the same engine serviced yearly used for my 18ft crestliner the carbs and engine uses specific amounts from idle to high speed 😮

The Yamaha oil injection system is actually much more reliable than the OMC VRO system. If you maintain it. Doesn't look like that motor got much maintaining in its life.

Would be a good maine digging boat!

Unfortunately if you do not remove the oil pump and remove the worm gear that drives the pump it will eventually destroy the bottom bearing in the motor. It will take some but it will happen. Otherwise great video.

How hard is it to remove the oil pump shaft?

So badass. I wanted to build a cabin using pvc filled with foam

Best video on you tube

What charging range do you get at higher rpms?

Thanks for the video, very helpful. Can you share the link or description of the stator that you purchased as I need the same for my Johnson 60hp

I wish I can find the stator for my 1988 mercury 80hp

Hi my meter has numbers on what number should I set it to test the stator

Thanks a bunch for the simplicity. You do a great job explaining how this stuff works

Too funny! I have a 1993 60 hp johnson on a pontoon that went out with no spark and I had to tow it back with my jon boat! Thank you for the video! Really helped me figure out how to test and remove the flywheel and stator!!

What was the primary reason for removing it? Just playing it safe? The Yamaha oil injection is one of the most reliable systems out there. Not very complex and very easy to maintain and repair. Unless its beyond repair I would never remove it. The benefits using the oil injection it that it uses way less oil than pre-mixing resulting in a cleaner burn, longer plug life, faster starts, better economy and way less smoke! Most overlooked items is the filter underneath the boat mounted oil tank which requires the tank to be removed to replace and the replacement of the oil lines(before they deteriorate). They may look good but they don't last forever. Somewhere I have a pamphlet that has theory and schematic which eases trouble shooting.

hate those old one piece stators. In late 83' early 84' OMC upgraded them to the ones previously used on the 9.9/15hp motors starting in 1977. Now you could replace either the charge, sensor or power coils without having to replace the whole thing. every chance I get i swap these old green monsters out for the newer ones.

great idea on the shower board stuff Bro!!! on a side note... whas that music if i may ask?

Hey brother so I am planning on doing that this weekend, I was out on the water today and alarm started going off, looks like my level was getting little low on engine reservoir I trim the motor up and alarm went away was able to get home. Looks like not getting from main tank into engine tank, anyways I have wanted to delete the precision blend since I got the boat years ago I’m always worried about it.. can you tell me what you did with the wires once you did the delete so the alarm does not go off.. thanks brother. Great video..

Can I just simply put pre-mixed fuel (50:1) in the oil tank so that I do not have to go through all these?

Yep just happened to me on my 1989 evinrude

Great video mate!! I enjoyed watching!!

How do you get the brass bushing out of it doesn’t come out with the shaft

Lol boat 😂

i picked up a deck boat with a 1996 115 yamaha . Did some of these come with out oil injection ?

😌 pքɾօʍօʂʍ

Cool. Could fish year round with that.

Why didn’t you remove the shafts from inside the pump ? This isn’t correct .

Where did you get those chairs ? Have an open floor on my pontoon boat, those would be idea.

Do you find it very top heavy going through wakes or the wind? Looks great.

Why did you stop uploading?

Please do a video on it in the water into that boat on the water you know like going 30 making turns and stuff hopefully doesn’t flip lol

Great idea however structure is gonna shatter after the wind hits it. Those shower walls are great for weather but entirely to flimsy with no real support behind them

So cool to follow this project! Can’t wait for another update. Also looking forward to seeing that beast in action.

Could you make a video on how you silenced the alarm and how you mix your oil for your system?

What electric meter is that?

Sounds like the engine is too weak or the pump is too big...
