Johnson 90hp with serial number R8258813 on freeze plug on top of block?

[chub]

Just bought this motor and trying to confirm if 90, 100 or 110?

R----might indicate a factory rebuilt / replacement block.----Pictures and jet sizes need to be posted.----Cylinder intake port size is ?

 

[chub]

I will post some pictures when I get home, what pictures would be best? The jet sizes are 36 air idle, 25c intermediate and 67c main

Back of the powerhead.----Cowling if it is original graphics.

 

[chub]

Cowling is not original, but here are the pics I have thank you in advance

 

[racerone]

It is not a 90 HP----If carburetor venturi size is 1 5/16" it is likely a 115 HP
