Easy easy but you do have to start with the later larger displacement 20 hp in order to get, inter alia, the larger flower-shaped leaf valves. Happy conversion to all !

That carb is a 30 A35 carb doesn't have that brass bar in side of the throat. You can take it out from the top crome cap ✌️gane 5 hp hope this helps

What is the difference between a 30hp vs 35hp carburettor?

Did it run good after the install

Can you do it with a 97

Hello, if someone could say what is the carburetor diameter of 20hp vs 35hp....thanks...

Inner Exhaust Covers are different between the engines. Throttle Cams were also different

Would this work for a 2003 Johnson 25 electric start

What about re-proping? was it necessary too?

This is so helpful, thank you. I'm looking at doing this same thing to my 20hp '88. Where did you get the parts?

Добрый день. Отличная работа! У меня такой же мотор, только с ручным стартером. Хотел поменять на электрический, но в нас в России запчастей почти нет на него

I did a lot of these motors 🙋🍿

What are the earliest/latest motors on which this upgrade works? I'd like to buy an evinrude, that has power pack ignition, but the pull rope part is not painted... So it looks early 80s

The line from the intake manifold connects to the primer jet on the top of the carb?

Some 20 hp reeds look like 3 leaf clover flower you have the better reeds biger hole for 30 35 look like triangle hole what it needs ✌️

I have 1989 model with electric starter. Thinking to do same thing. I have couple questions

Hey just fyi the timing is different also need to open up reed stops. Great stuff here

your nails are longer than I've ever seen on a male before......???

You obviously don’t know what you’re doing, the 35 block is completely different than a 20! Absolutely erroneous information!
