    NS40C Missing

    If it's a new CD it should be fine. In the Factory service manual is a table to check the CD with an under 3v analog ohm meter. If you go above 3v, you can cook the CD. Here is what the lube line looks like (item 3 in the diagram).

    Need help with a part for Tohatsu 5 h.p MFB

    So your actual model is probably M5B. Keep an eye on the old tank, as it is NLA. The very early version of the recoil is NLA. After serial 44000, this is the recoil used. The assemblies do interchange. The Which part do you need?

    nissan nsf15b primary jet setting

    No, No. No. The jets are not adjustable. Period. Look at the diagram. The jets must be seated all the way in the bores. If you are starving during acceleration, you are probably experiencing junk in the passages -- varnishing. The 15B is particularly succeptible to that, because the passage in...

    Tohatsu 5 HP 2 stroke problem

    No. That setup is for when the 5 hp motor is the dual-tank version. For the internal-only tank, the fuel screen is inside the tank, attached to the fuel ****.

    Nissan 15 hp lower unit removal

    The bolt you are showing is for the stopper for the cam rod. Item 8 in the drawing.

    Nissan 15 hp lower unit removal

    That bolt is irrelevant. There are 4 nuts on 4 studs (and of course the shift linkage), and that is all.

    Correct Prop Hub?

    I have a pair of Merc 115's on a 50-foot pontoon boat. The serial number is: 2B151536, model is 115F631D. The props are "loose" when the prop nuts are tightened all the way down. I replaced one prop and hub due to damage, and that one is now fine. So I got another hub kit of the same kind (Flo...

    Tohatsu 3.5 drive shaft bushing

    We really should have your precise model, not just horsepower. It's always best to replace the complete wp kit, instead of just the impeller; pumps better, and lasts longer. There is a bushing used on some long models that reduces drive shaft whip. here is what the page from the parts catalog shows:

    2011 20 hp Tohatsu carb leaks

    There isn't any overflow pipe. If you left the plunger installed while in carb dip, it probably is shot now. Where exactly on the diagram is the leak?

    How to detach 2006 9.9hp tohatsu cables from motor

    1. Throw that generic manual away. Get a Factory service manual. Tohatsu/Nissan motors are not referred to by year for servicing, but rather by actual model/serial. 2. The motor does not need to be removed to do "spring maintenance", unless the boat is in the water, and then only to change the...

    The rectifier/regulator is NOT under the flywheel; it bolts to the intake manifold.

    Small oil lower port on NS40C lower unit

    The upper and lower plugs should be identical. They are metric, so if your pump is setup for the old OMC drains, you need an adapter. The fill/drain plugs are items 3 in the diagram. Item 36 is the cam rod bushing stopper, not a drain plug. You can d/l your owners manual from...

    Engin Basement Gasket leaking

    With a long shaft motor, the prop stays submerged. The motor is in its own compartment, so it is very quiet, especially since it's a 2-cylinder 4-stroke. No gasoline inside the cabin, either, so safer. No hole in the bottom of the boat to leak. This ends up being a fully Remote motor, with...

    2000 Yamaha 4 hp 4-stroke tiller handle is floppy

    I have a friend's dinghy motor, Yamaha model F4MSHY, which runs well, but the tiller is "loose". It's fastened to the 4-piece carry handle and lower cowl fine, but it seems there is a "steering bracket", apparently now obsolete, that is supposed to bolt to the bottom of the block, and keep the...

    Nissan 3.5 doesn't engaged forward

    That shaft has 2 o-rings, and should have been greased from the factory. There is also a ceramic ball detent with a spring that holds it in either N or F. You may want to lubricate it, but if so, don't lose the spring and ball, and expect to need new o-rings:

    Engine Temperature and Starting

    There is a low-pressure fuel system that feeds fuel to the separator, which has a float like a carburetor. Inside the separator is the high pressure fuel feed pump, which pressurizes the fuel rail. In addition, there is the low-pressure filter, the high pressure filter, and the fuel cooler, as...

    2002 Nissan 6hp long shaft bushing stop

    The bushing is pressed (a little) into a casting... the whole thing is called the bushing assembly. That is retained by the stainless stopper plate and that is all held in the housing with 2 stainless screws. No, I'm not at Obersheimer's any more.
