2004 6.2L Bravo 3 on a Regal 2665 Commodore...

Has anyone ever done this?

I want to run a short extension hose from the grease fitting on the side of my transom housing, about one foot to a more accesible location... Due to the extra swim platform extension, I can't get to it unless the boat is out of water... I am replacing my Gimbal bearing and u-joints, but want to keep it lubed as directed in the manual... I would, of course remove the exisiting fitting and thread and seal some type of 1 or 2 foot extension hose, similar to the ones that come with the grease guns..., and mount it to the small hole where the transducer wires comes up through the swim step...?

Are there any issues with something like this?
