Lower unit fill/drain screws

[Tim Frank]

Have a Nissan 40 HP 2 stroke, 2005.
Anyone know what thread is on the fill and drain screws for lower unit?
I just bought fill pump for two small 'rudes that I have and want to adapt it somehow so i can use it on the Nissan.
Alternatively, any online source for a pump that will fit Nissan lower units?
The pumps are not that expensive.

Its the same metric thread that is used on all the other Jap engines. We just use a rubber grommet on the end of our filler and hold it in place rather than screwing them in.

You can also get an adapter that converts the pump tube end from OMC to Nissan. The dealer that sells the pump should be able to get one for you.
