1988 Johnson 4 Hp Sailmaster operating perimeters

[j_k_bisson]

I recently acquired a 1988 Johnson 4 hp Sailmaster (J4RLCCS) that is in near mint condition. I have purchased a factory service manual and have rebuilt the Fuel Pump, Carb, primer/choke system and installed a impeller rebuild kit. I can get it to run great at both Idle and High RPM's.

My issue is with the timing/carb settings seeing the throttle is on the top of the motor and the carb settings for the idle speed jet on the front. I have read all the service manual and cannot find the idle jet pre-setting. I want to confirm this setting before running for a long time, so I do not run it too lean.

What is the idle jet setting for this motor. It is referred to as the "4 hp Ultra" in the service manual.

I'm hoping someone can put me in touch with where i can get the original operators manual for this motor. There has to be directions on how to run this. Any and all help welcome.

The idle mixture needle is usually set at 1-1/2 turns out.-----Then you must adjust once motor is warmed and working on a boat.------Note ----The idle mixture being too lean will NOT damage your motor.

As racer said above. Set it as lean as you can and still get a reliable idle without coughing or stalling.

Doesn't always work, but with the small motors you can often get it to idle low and slow, with no rpm change going into gear (or almost none). Technically, the mix adjustment is supposed to be made with the motor in gear, but I do it in gear or neutral as long as the motor is warmed up. Shifting into gear, though (or in and out of gear), is a test for settings. It probably ain't set quite right if you stall trying to ease your way out of the lily pads -- or trying to ease your sailboat into the slip.

The Original owners manual can be bought , as stated by FR above, from Ken Cook Co ( same place as the Service manual)

I don't. Except I do know that Ken Cook held the sole license to reproduce and sell OMC factory manuals a long time ago and still does.

Ebay seems to be a good place for manuals as well. I bought 2 OEM 4hp manuals. One for a 1981 4hp for $10/ shipped and one for a 1993 4-10hp for $25 shipped. Both from same seller. You don't have to have the year on the money, for instance I have an '82 and a '97. But '81 and '82 are mostly the same, and '92-'97 are basically identical. I got the best deal that I could find

 

[oldboat1]

I doubt the operator's manual would get into issues like initial needle settings. Wouldn't hurt to have one, though, to see what tidbits you might pick up.

Ebay sells everything. It was new for $8.10, shipping included. They do not have the Operators manual. I figured with the top of hood mounted throttle controls are new to me and I am looking what it says about how to set these when in use.

 

[racerone]

Just a sliding throttle control.----Just slide it to get the speed you want.

Not sure that model has a shifter for F and N but if it does, just make sure it's in the shift range when you shift it.

If using it as a troller (on the Bayliner?), it might be useful to have a top mount control kit that allows you to pull it over vertically. Also, there are trolling motor mounts that can be removed from the transom -- slides in and out of a sturdy aluminum mounting plate. I think they are still manufactured (Garelick?), but otherwise out there on Ebay or garage sales.

I actually sold the Bayliner about 7 years ago. My 3 girls did not like fishing, they likes swimming. So we sold the boat and put a pool in after I mentioned to my wife the amount of literal "crap" in the great lakes.

So this year I finally got back into boating with the purchase of a 1993 Lund Pro V 1775. I resurrected my old kicker motor, a 1981 Honda BF75 with replacing the impeller, fuel lines, rebuilding the carb, and fuel pump. But it is quite heavy at 76 lbs plus weight of a 3 gallon fuel tank. I pre-mix the main tank on the boat for 2 stroke. So with the new 4 hp 2 stoke, I get rid of the addition fuel tank and this new motor is only 36 lbs or so.

I don't need the vertical pull start, as there is plenty of room.

Hey -- nice boat. Wide and stable.

Thanks. Thinking this is what gets me thru the next couple of years...
