Hi all can anyone tell me the correct oil to put in the trim and tab pumps , the tab pump has kiekhaefer wrote on it and says 10/30 or 10/40 is this just motor oil ?? the drive pump oil looks thinner but it does not say on the pump wot to put in it . thanks for any help . paul

Mercury/Quicksilver power trim and steering fluid #1
or you can use a 30 weight oil that makes you happy. The Merc stuff has anti foaming agents in it and is non detergent.

i have always used 10/30 never had any issues with it.

X3 and any viscosity will work. Thinner oil will run the tabs/pumps faster.

Thanks guys , i did take the time to read up in my SELOC repair manual befor i posted , but it contradicts itself, in one section it says you can use 10/30 oil in a emergency , but drain as soon as poss , then in the maintenance section , it says you can use 10/30 oil and nothing about draining it out?? so i thought i would see wot you guys are putting in the pumps . Its unanimous 10/30 thanks .

I run tranny fluid.

Works great

We are talking auto/trans oil , the red stuff ?? , this would be good for me as i allready have plenty , would i be correct in saying its thinner and therefor run the pumps faster ,seems strange that it seems you can run almost any oil in the pumps and no damage or wear, i mean you could'nt run 10/30 in a auto/trans could you ??? i am no expert thats for sure but i do not want to wear out 4 pumps ,thats why i came on here for some advise Thanks all for the impute regards paul

I use tranny fluid in all 4 of my pumps.
