Hello,
I have searched high and low for an owners manual for my 1998 Johnson Seahorse 4HP Model #J4BRECJ, but cannot find one (it is a pull start). I am having trouble sorting out the controls on the engine and getting the engine to start and run correctly. I do believe that the problem is me not understanding the controls correctly. Here is what the controls are.
- Twist throttle on handle, which I know controls the gas
- Knob that can turn to a gas pump/tank icon and to a gas pump/tank icon that is crossed out (not sure if this is the control for the gas shutoff or the choke)
- There is a choke symbol below this knob to the left, but you cannot turn the knob to it.

My main issue is that I cannot get the engine to run, mainly because I cannot figure out how to choke it and if that knob is controlling that or if it is controlling the flow of gas. Any help is greatly appreciated.

Thank you and God bless,

Matthew

It probably has or had a small fuel tank built into the outboard and can also use a remote fuel tank with hose. That switch would be to switch between the 2. However, i can not be positive.

It does have a small tank built in, which is what I am using. There is also a connection on the front for an external tank.

Re: Controls on 4HP Johnson

I just found an expanded view of the carb assembly. Below is a link. The knob is #42 which controls the shaft #38 which is called the Choke and Fuel Shutoff shaft. So, would pulling this out choke the engine and turning the knob control the flow of gas? Thank you and God bless.

I am not sure. Someone who knows for sure should be along sooner or later.
