Default Oil Change

Hello All-

I went to square away with my local marina for winterizing my 4stroke 60hp Merc. They didnít change the oil as requested. The boat is back home in the garage with battery out for the winter (Northeast - cold). They would like me to haul it back for an oil change. Itís not the end of the world as it is in my garage uncovered.

Is it something that should be done or can it wait until spring. Would it effect anything else they did during the winterization (changing the lower unit oil, fogging the cylinders by spark plugs)?

Thanks.

It more than likely will not harm anything if you wait till spring. I personally would do it myself... VERY easy to do especially if its in your garage.
And no, it will not affect anything else.

Engine oil on a Merc 60 is real easy.
Tilt it up and down before you drain it to be sure all of the oil has drained into the sump.
Pull the plug on the leg, drain it, spin off the filter, spin on a filter put the plug back and pour in the new oil. It is a little bit of a trick to get the bucket under the drain, hold it there and unscrew the last threads on the plug but other than that, nothing is tough. I wrapped an old towel around the foot to catch the drips when I did it in my lift and usually I did not even lose a drop or put a trace of a sheen on the water.

It is best to have the engine/oil warm when drained. At this point, I would either DIY or wait until spring.

I do not know how many hours are on this oil. I only bought the boat at the end of the summer I believe the oil was changed at the beginning of the summer.(id have to look at previous owners paper work as I forgot). The engine is a 2010 and the total engine hours is 121, so not many hours per season!

That is my only concern having to start it up and warm it up to get the oil flowing as it is 18 degrees in NY right now.

Somebody explain the logic in draining the oil when the engine is hot. I know that is the urban legend your great grand daddy told your grand daddy but we use multi viscosity oil these days. Isn't cold oil 10 weight and hot oil 30 weight? Why would 30 weight flow easier than 10 weight?
Besides, wasn't the oil hot the last time you used the motor and hasn't it been draining down intro the sump for days/weeks/months?
Just pull the plug, let it drain a few minutes and call it a day.
You can bet your ass the dealer is not waiting for the engine to get hot before he drains it. That boat has been parked along the fence for a few days, he drags it in, does the service and parks it back against the fence. Most of them suck it out the dip stick hole these days anyway.

Normally oil changes are recommended to be done at fall/winter layup to especially remove any elevated acidity present in the oil due to the byproducts of combustion.
But , if you have planned to have the mechanic commission your engine in the spring, it's not going to do apprecaible harm to wait until then. Just mark you initials or date on the filter so you will know it's been replaced later.

Or, as others report, w/o running it , it shouldn't be difficult to change it yourself in the garage on the next warmer day and perhaps with the help of a flood or reflector lamp aimed at the block for and hour or 2 to help a bit with oil flow. Doesn't matter if it just flows a little slower and takes a little longer. Can you heat your garage too?
Then mark present engine hours and date and oil type on the filter and in your log book so both you and the mechanic remember it has been done and when, and can keep track of the change interval relative to Merc's maintenance schedule.

It drains faster and more thoroughly. It's preferred, but not absolutely necessary.

From experience I had with car engines and inboard boat engines, you can DRAIN motor oil when its cold but if you want to suck it out with a vacuum pump, forget about that working unless the engine is at least warm. If this engine has been getting regular oil changes, I would not necessarily worry about it if you have to wait till spring. Yes it is optimal to do it in the fall so as to store the engine with clean oil in it. However fuel injected engines run so much cleaner (assuming no fuel dilution) than carbed engines the motor oil should stay clean longer.
