Engine model number

[markhodges78]

I have 2 engines I am trying to locate model/ year of production for the serial number of the first 1 is R8180101 it is a 25 hp Tracker / Evinrude

The 2nd one is R8225860 with a partial model number of E100S it is a 100 hp Evinrude I have posted pictures as well

The cowl will provide no insight. There should be a plate on the transom bracket that will tell it all.

Yes in a perfect world but unfortunately the 25 hp is gone and the 100 hp is only partially there

A missing plate could indicate a stolen motor. Google OMCs database and look up your serial numbers. At the very least It would probably identify the year of manufacture.

It’s not completely missing

It’s not completely missing

Also the input shaft has a metal woodruff key for the water pump instead of the normal plastic keeper

Post some ( 5 or 6 ) of the powerhead.----The 100 HP version was marketed in 79 / 80.-----Then again from 88 to 94.----And it could be that the later midsection was put on an older motor.----Or an older lower unit put on a newer motor.-----This is what happens with numerous owners !
