would it hurt to just drain lower unit oil in my 70 hp Johnson 4 stroke and leave it m/t till spring then fill it up when it warms up..don't know if I'm going to make it anywhere to get the oil soon and its supposed to drop down in low/mid twenties later this week.Im thinking it wont hurt anything as long as don't forget to put it in in the spring.
If you do put a big ole sign on motor ( No Lower Unit Oil )
yea that's exactly what I would do..

No way would I drain the lube without refilling the lower Unit
Just pull the bottom plug and put it right back in. If there is water in the lower unit you will see it. If oil is OK then leave it tell spring or when you have time to go get some more. I order my online from amzoil and they ship it to your house. It a great synthetic oil. Its all I use in my lower unit and gas. After paying to have my motor rebuilt it worth what you pay for it. The engine in my truck would have been cheaper :)
That is a definate possibility....no way would I do thatQuote:

Would regular oil work for a filler till you change it in the spring?
drained oil should of just left it looked like brand new..I would think only way it would get condensation is if there were really wild temp swings, no air is going to get into it and everything will have a coating of oil on it would think it would take a long time to get completely dry.
Will probably see if I can get some from the boat dealer tomorrow between running around and put it back in.
Lol you can always do like poor shops do . Take out the top screw and stick a broom straw down to oil . If its clean , they leave it. All pays the same . :dono
Bad deal...cause if it does have any water in it you won't know it...., oil is less dense than water, and floats on top of water because oil weighs less than the volume of water it displaces. The water will be on the bottom.Quote:

Never seen water in oil that the oil was clean . Was not saying its the best way but had rather do that than leave empty . jmoQuote:
