    Fuel Line USCG Type for Under RIB Floor

    OK thanks, I will go with the A1 since I don't know whether I would comply with fuel discharge section (b) (2) (ii) of 183.558. Any experience with flexibility of the Trident Marine A1-15 Part Number 365-0560 ?

    Fuel Line USCG Type for Under RIB Floor

    I am moving my fuel tank to the bow locker on my Highfield Classic 290 Hypalon RIB. Is USCG Type B1-15 hose acceptable for the entire run from the bow gas tank to the engine, or is USCG Type A1-15 required under the floor from the bow gas tank to the water filter separator on the transom?

    1987 Johnson J15RCUD with Racor Filter and Longer Fuel Line Run

    Thanks for your thorough reply to my questions. I was not aware of the Racor SNAPP filter series. At first glance it looks like a lower cost option, but the overall size seems larger. I'll also stick with the 10 micron filter given your comments. My main concern is not to have a fuel delivery...

    1987 Johnson J15RCUD with Racor Filter and Longer Fuel Line Run

    I am using this motor on a rigid inflatable boat (RIB) that will be used on a cruising sailboat. I am interested in adding a Racor 120R-RAC-01 fuel filter and water separator to clean fuel purchased in the Caribbean islands. I am also moving the gas tank to the bow locker of the RIB. My...

    1987 Johnson 15 HP Choke Linkage Hanging Up

    I disassembled the choke linkage and shaft assembly. I moved the location of the Choke Override Spring end creating more torsional force which ensures the throttle plate pivots with the Choke Lever movement. This has corrected my problem. See attached image with red arrow showing the proper...

    1987 Johnson 15 HP Choke Linkage Hanging Up

    Is the end of this spring in the wrong location? The spring is identified by red arrows in attached pictures and #14 in above diagram. When closing the choke valve, the choke plate shaft does not rotate with lever (#19) movement. I believe the black plastic part (#24) should remain in contact...

    Racerone, You Called It! I replaced the Power Pack and the engine fired right up! I'm happy I was in the 90% club for the above symptoms described! It's on to some tuning. Thanks for the help!

    1987 Johnson 15 HP J15RCUD Lost Spark

    I performed a Stop Switch Test and checked the Ignition Coil, Charge Coil, and Sensor Coil resistance measurements. All resistance measurements met specification. I purchased an Electronic Specialties Model 640 Direct Voltage Adapter for use with the Klein CL800. I checked and passed the Charge...

    1987 Johnson 15 HP Choke Linkage Hanging Up

    Racerone, yes, since this 1987 is new to me, I successfully rebuilt the fuel pump given the diaphragm may be 38 years old.

    1987 Johnson 15 HP Choke Linkage Hanging Up

    This is a 1987 Johnson 15 HP engine (J15RCUD). Model number confirmed on transom bracket sticker and engine block Welch Plug. This was a transition year for the carburetor and fuel pump designs. I have the early carb version depicted in your diagram (not the newer carb with plastic top), and...

    1987 Johnson 15 HP Choke Linkage Hanging Up

    I will attempt to explain my concern. The first image below (Choke Closing / image 1) is taken when moving the longer lever arm (moved by linear motion of choke in outboard assembly) to close the choke valve. Note the black plastic piece, on the choke valve shaft (shorter lever arm), stays...

    1987 Johnson 15 HP Choke Linkage Hanging Up

    This 1987 has the early carburetor on it, not the later carb with plastic top. My choke linkage occasionally hangs up in the closed position when I push the choke in (no choke position). If I understand correctly, this linkage allows the choke plate to be closed, and if a lever override exists...

    Water Pump Kit P/N 394711 for 9.9 & 15 HP Johnson

    OK, thanks for the explanation. I don't have a groove around the top of my 1987 15 HP driveshaft. I just wanted to make sure I wasn't missing something on the assembly.

    Water Pump Kit P/N 394711 for 9.9 & 15 HP Johnson

    This kit comes with an O-Ring (item 5) with an internal diameter of approximately 3/8". Where does this O-Ring go? I can't find it mentioned or on any parts diagram in my OEM Service Manual or the water pump kit instructions.

    1987 Johnson 15 HP J15RCUD Lost Spark

    OK, I will order a new powerpack. Also, once I get the Klein CL800, I will try and use it to measure peak voltages for the cranking tests. Thanks! PS; flyingscott, your avatar brings back memories. My father had a 7 1/2 HP Scott Atwater with Bail a matic. It was a fine outboard that served us...

    1987 Johnson 15 HP J15RCUD Lost Spark

    I believe the black kill wire is the "E" terminal on the 5 pin Amphenol connector. If I understand, you are suggesting the "Stop Circuit Test" in the manual. Thinking I performed the "Stop Switch Test" to confirm kill circuit functionality, I was reluctant to pull the "E" pin from the Amphenol...

    1987 Johnson 15 HP J15RCUD Lost Spark

    New to me 1987 Johnson 15 HP engine J15RCUD. I was told this engine hasn’t been run for 4 years. This engine has the newer style fuel pump p/n 399857, but early style carburetor with metal bowl. I understand this was a transition year for the new fuel pump and carburetor, but the carb is the...
