From a mechanical stand point, it is better to leave an outboard tilted up or down?

Long term?

Short term?

Carborated or injected?

In the water?

On land?

Winterized?

Thanks

Re: Is it Better Up or Down?

Winterized outboards should ALWAYS be stored down to allow them to drain properly. Trapped water freezes and breaks things. Whether winterized or not, storing the engine tilted down would be better since the tilt rams would be retracted and therefore wouldn't rust or become pitted. For trailering, tilted down is best but if there is not enough road clearance, use of a transom saver is recommended to keep the motor from flopping around and exerting stress on the transom. Other than the above concerns, injected 2-stroke motors don't care how they are stored. 4-stroke motors should always be stored according to the manufacturers instructions when off the boat (as in small outboards). This is because crankcase oil can leak out and really screw things up. As for tilting, again they don't care except for the above concerns. Long term storage the engine should be stored down for all of the reasons indicated above. In nasty water you would be best off tilting the motor out of the water and hosing it off frequently. In those instances you are not likely leaving the motor in that position for extended periods so it shouldn't bother.

The 2 posts above hit the nail on the head and I agee 100%. Also if you have a carbed engine you might get fuel,etc draining out the carbs over a long period of time. Again, always store the engine down.

Re: Is it Better Up or Down?

i always leave me outboard stored up? its carbed but i drain everytime i shut it off for a week or so. but even if i dont drain fuel stays in place except maybe the fuel line which leaks out.

i mean what about mainre growth on the lower unit? does it really matter whether its up or down?

Re: Is it Better Up or Down?

When in the water, mine comes up in between uses.
When in the driveway or trailering, it is down.
When on a stand, it is down.
When not mounted, it is horizontal facing up.

Re: Is it Better Up or Down?

i said my post wrong. what i meant is if the boat is in a driveway i would store the motor down but there is sometimes when a person might have to stroe it up. but i guess the main point is store down when ever possible? unless ur in the water especially in salt
