1981 115hp water pump

[mike69infl]

Im trying to change the water pump on my 1981 Evinrude 115hp motor. I removed the 4 lower bolts and the larger one by the prop. I cant seem to get the lower end free to drop it down. Any suggestions?

Take the skeg off, and you'll see another bolt under it.

The skeg?

Does anyone have a parts diagram to show the bolts to be removed in order to drop the lower end on a 1981 Evinrude 115hp OB?

I think ledgefinder intended to say the "trim tab", not the skeg. Trim tab is the little fin above/behind the prop under the cavitation plate. You'll find another bolt underneath the trim tab that needs removal.<br /><br />Also, you'll have to disconnect the shift linkage in order to get the lower unit to drop. Linkage is typically underneath the bottom carburator on the powerhead. Can be a bit awkward to get at sometimes.<br /><br />Finally, I'd get a manual. The few bucks you spend on it will be returned ten fold after just a couple repairs.<br /><br />Good luck!

Seaman, you are refering to the 5/8" bolt above the prop correct?

There are two above the prop. The one under the trimtab is smaller than 5/8".
