    tohatsu remote control cable

    Sounds like you are already setup as remote... cool. The CD is the Capacitive Discharge ignition module (the magneto). If you ground Brown, the motor stops. The Remote kit uses a special cable end that does a twist into the shifter arm. See the diagram. The end bits are available. Use standard...

    1988 Nissan 55HP Lower Unit Issues

    The picture doesn't show all I would want to see... is the spring OK? If the ears on the clutch dog are rounded or broken, it would chatter. What are the actual symptoms? It should look more or less like this:

    How To ID And Upgrade Tohatsu 9.9 To 15?

    1. That book is worthless, except as tinder for the woodstove, or as Elvin used to say, maybe a doorstop. 2. Get the correct Factory service manual from any Tohatsu/Nissan dealer (you can use the dealer finder from the Tohatsu website). The manual will be a combination manual for all the...

    9.8 hp 4 stroke Nissan lower running gear leak

    The LU on the 9.8 isn't mysterious; There is a seal for the drive shaft, and one for the prop shaft. There are also o-rings for the shifter cam rod, and the prop shaft housing:

    no spark, won't start

    IF you have had the prop housing out... the push rod 25 that operates the clutch probably fell out of the end of the prop shaft.

    no spark, won't start

    If you are unfamiliar with the neutral safety, it may be best to see your dealer. But, if you want to tackle the job... See pages 38 and 39 of the owner's manual at http://www.tohatsu.com/tech_info/own_man_pdfs/Toh_MFS8A3_98A3_003-11082-9.pdf about how to remove the recoil starter in the event...

    Nissan/tohatsu 6hp shift shaft woes

    I take it that you still have the LU down. Seems you are in F (cam 47 rod is up). Since you can rotate the cam rod, you likely pulled the cam rod up too far -- out of contact with the push rod 23. At this point, you need to rotate the cam rod so that the flat side of the sliding cam faces aft...

    tohatsu 9.8 corrosion on vertical shaft

    1. The shifter is not inside the steering swivel shaft, it is forward of the actual shaft. 2. You do not need to (but you can) remove the power head to expose the steering shaft bushings, but you will be separating the lower motor mount brackets to disengage from the tilt/swivel bracket. In...

    98 Nissan ns15d2 regulator rectifier wires

    Understand that any single-phase bridge rectifier receives 2 wires as AC input, and then provides rectified DC out. Yellow/white are your AC. Black is common ground. The schematic in the owner's manual doesn't delineate the wire, but shows it capped off in a non-charging setup. Review the...

    Tohatsu MFS15B2 Carb issues

    You may have a damaged or missing part. No, there isn't any o-ring associated with the emulsion tube nozzle. However, it is critical that the rubber plug/cap be installed in the slow jet bore, or mixtures will be crazy rich. It's also very important to have everything related to the accelerator...

    why my 9.8 Tohatsu won't start with pull starter

    tach question for a 1998 nissan 25c3

    Re: tach question for a 1998 nissan 25c3 The sender goes in series in the white wire of the tach signal wire. There is also a yellow tach "ground" wire -- hence we refer to the tach wires as being yellow and white. (BTW, Your manual does not take into account the new-style tach, which came out...

    Lower unit stuck on 18hp nissan

    Re: Lower unit stuck on 18hp nissan You may have a stuck driveshaft. Either the splines were not greased the last time the LU was down, or maybe it has never been down, or the driveshaft could be twisted, if the motor hit an obstruction. The technique to free the LU when the driveshaft is...

    Re: NS5B Gasket kit sourcing. The rubber plug covers the slow jet. That forces the slow jet to get its supply via the main jet. see the diagram:

    Water pump issues

    Re: Water pump issues Luis does have an OK "shade tree mechanic" way of determining whether you have any pumping at all. But, in all fairness, Elvin is (as usual) correct. The wp kit likely needs to be replaced. 361873220M WATER PUMP REPAIR KIT 25B-40C $46.67 If you are going to turn your own...
