    Torque for 4 B cylinder head (Please)

    Tighten as you would a 5-lug wheel; skip across one bolt as you go, in a "star" pattern. Torque up in at least 2 sets (half torque first, etc.). Here is the torque chart:

    tohatsu 30 hp efi 4 stroke

    There is an aluminum casting bowl that houses the electric fuel feed pump. It has a small brass drain screw. That should be drained any time the boat will be laid up for a month or so. That is the vapor separator. Item 1 in the diagram. There is also the high pressure fuel filter, item 34 in the...

    2001 nissan 15 hp 4 stroke

    Year is unimportant; Model/serial is everything. You probably have an NSF15B or B2. Best to buy a Factory service manual from your dealer (not an aftermarket manual). Here is the page from the parts catalog that shows how the carb goes together. Yes, the emulsion tube nozzle just slides in/out...

    Tohatsu Sailpro 6 - this CAN'T be normal, right??

    Depending on the lube used, the grease may have softened the rubber bushings. It won't hurt anything. Those bushings help dampan the 1-cylinder vibrations so they don't shake the transom as much. You can get new bushings, but they probably aren't a lot stiffer. Also, if you want the motor locked...

    Tohatsu Sailpro 6 - this CAN'T be normal, right??

    The usual cause of that kind of issue is either over-lubrication with way too much grease, or grossly over-tightening of the friction band, or both. On sail applications, consumers sometimes try to use the friction band as a steering lock, and damage the mechanism. Tohatsu actually makes an...

    Tohatsu MFS 4A external fuel does not go in

    It depends on which way the fuel **** is set. The check valve (27 in the diagram) is supposed to allow external tank fuel to enter the system. The fuel **** is there to shut off the internal tank. If the **** is set to allow the internal tank to flow, and you pump the primer on the external...

    Nissan Outboard motor

    Your model number makes no sense. But... those size Tohatsu/Nissan motors have a grommet there to access the shift linkage. It will be loud with that missing. 369610160M GROMMET $3.15

    2005 Tohatsu 30hp gear housing stuck

    Shouldn't matter whether it is in gear or not.

    Nissan 9.8 only runs in reverse

    Odds are the shift rod (19) has popped out of the shift rod lever (11) .

    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...
