I have a Mercury branded Tohotsu 5hp sail pro kicker motor.  I tried to change the lower end oil today.  Unfortunately, it uses smaller ports than my 50hp Merc, so I cannot use my oil pump to fill it back up.

Has anyone else run into this issue?  Do you know anyone who carries; either an adapter for a standard oil pump, or a smaller sized pump for these outboards?

I've found that the tips you get with a tube of RTV sealant will thread onto one of the threaded adapters that came with the cheap pump and I use those on one of my engines. Just clip it to the correct "step" diameter to work. On another engine I use a tip from a tube of hemorrhoid cream.

Turkey baster.

If one squirt isn't enough; put your finger over the check plug hole. Very little oil will come out of the fill hole. Recharge the baster and repeat as needed.

I didn’t think most guys would admit to having undersized lower end ports

LOL

Well, the issue is that my tool was too large for the hole.  I had to find someone with a smaller tool...  ?
