Looking for suggestions

I just finished installing some lenco trim tabs. I took off one of those whale tales. My question is there are two holes in the fin of the motor that the bolts went in, should I fill them somehow are will they be fine just leaving them like that?ImageUploadedByTapatalk1392408370.218808.jpgImageUploadedByTapatalk1392408381.451883.jpg

I took a tail off a 115 Yammy didn't fill holes only thing i noticed was water would shoot out when running but didn't notice any negative influence.
