    Low Idle RPMs

    I've maxed out the star wheel adjuster to set the idle speed on my 1994 Evinrude E115TLERC 115hp Outboard Motor. I need to increase the RMPs by 200-400 for smooth idle when in gear. Right now I can get no more than about 400-500 RPMs. What can I "adjust" to increase it a bit?

    Strange Idle Speed Problem on 1994 115HP Evinrude

    The idle speed of my 1994 115HP Evinrude significantly decreases when I put the cowling back on! It will run relatively smoothly :) at about 900-1000 rpms with the cowling off. However, after I replace it the rpms drop by several hundred and the motor runs rough and wants to stall. At higher...

    Cruising RPMs

    What would be a good rpm reading for fuel consumption/speed for my 18HP 2 Stroke Nissan motor (NS18E2)? It has a 10in pitch stainless steel prop and turns about 5400 rpms at WOT. The speed is about 23 mph on my 15ft Jon Boat.

    1999 Nissan NS18E2 Idle Problems

    I'm having difficulty getting a smooth running idle setting. I'm about 1 3/4 turns out on the idle jet and running about 1500-1700 rpm (Hardline Tach) in neutral. When I pop it in gear, its a rather rough running 1200-1400 rpm. If I adjust the neutral idle rpm down, the motor dies when popped...

    Will a Mercury prop fit and work on a Nissan motor?

    Will a 9.5 X 8, 14 spline Mercury prop fit a Nissan NS18E2 (1999 18hp) motor? Would it essentially be the equivalent of the OEM 234 cm X 999 cm (9.2 X 7.8) prop?

    When will it be Obsolete?

    I'm new to Nissan/Tohatsu motors after being an old early 80's Evinrude owner. After reading posts to this forum, I not likeing what I read about the availability of parts for older N/T motors. This really wasn't a problem with Evinrude/Johnson motors. I have an NS18E2 (1999 Nissan 18hp...

    "Standard" OEM Porpeller for 18HP Nissan NS18E2

    Does anybody know what propeller (diameter X pitch) this motor was equipped with from the factory? Would that be considered the "general purpose" propeller? Please forgive the typo in the tread topic.... I couldn't go back to correct it!

    How can I protect the prop and prop shaft?

    I'm new to Nissan/Tohatsu motors. I had a 7.5 HP Evinrude that used brass shear pins. On several occasions, I have sheared a pin during a small creek or low water river trip. The NS18E2 that I just bought, has a stainless steel prop. I took it off and discovered that it does not use a shear...

    25HP Johnson "starving" for fuel

    I had my 1990 25HP Johnson (TJ25ELESE) at WOT today and it suddenly stalled-out and died. It had an excellent "pee" stream and the overheat alarm never sounded.... so I don't think that it overheated. The only way that I could restart it was my priming the carb by the usual pushing in (pumping)...

    Does it have a battery charger?

    Does my 1990 Johnson TJ25ELESE 25hp Outboard have a charging system? I installed a voltmeter and I get no indication that the battery is being charged while under way.

    Coughing, Sputtering 1990 25HP Johnson

    My 1990 TJ25ELESE 25 HP Johnson is suddenly coughing and dieing. It starts fine, idles OK (a little rough) but when I increase the throttle it coughs and quits running. I limped back to the dock at idle speed yesterday. Today I checked the plugs (OK) and compression (OK). Then I switched to a...

    Vapor Lock?

    I've witnessed something strange this evening. I replaced the water pump on my 1992 25HP Johnson. Before reinstalling the LU, I made sure that there were no obstructions in the cooling channels by flushing water through the water pipe until it came out the pee outlet. It came out in a strong...

    Water Pump Rebuilt Project, 1982 7.5HP Model E8RCNR

    I'm trying to talk myself into my first project of this sort and I need some words of advice and encouragement. I'm of the "if it ain't broke.... don't fix it" school and the pee stream is currently very strong. However, I do not know when the Water Pump was last replaced. It seems that a...

    Possible Water Obstruction in Cooling System?

    The pee stream on my 1990 25 HP Johnson all of a sudden stopped. I thought that it might have picked up some debri and that I have something clogging the cooling system. I blew air into the pee hole and I get plenty of bubbles from the water pickup ports. Does this prove that that is no...

    Cleaning High Speed Orifice of 1990 25HP Johnson (continuation of earlier post)

    To correct a rough running engine at high speed (idle seems OK), it was recommended that I try poking a small wire through the high speed orifice or just bite the bullet and rebuild the carb. I want to try something short of the rebuild. Can I/Should I; 1) leave the high speed orifice in the...

    25HP Johnson running rough at high speed

    I'm working on a 1990 TJ25ESLESE 25HP Johnson that has been stored for several years. It started fine and had balanced compression at ~ 105 psig. After doing a decarb the compression is up to ~115 each. I changed to new plugs and ran it with water muffs. It seems to idle well enough but it...

    Air Filter for Small Outboards

    I'm new to outboards. The few that I have worked on don't have an air filter or any type of paper or sponge element. Is this common? Can/should one be retro-fited?
