How to fix a leak in 2 inch hose?

[FASTFJR]

I have a 2011 Strong Milan tub. I noticed a few weeks ago the water level going down and a wet spot on the pavers. It took a while but I traced it back to a pin size hole (only leaks when motor is running) off the secondary pump. Anyway I'm not sure how to fix it. I did order a 2 inch coupling. My main concern is what to use to cut the hose?
 
I've never fixed any of these hoses before, I had a leak in one a few years ago and it was replaced under warranty by a tech.

Just and FYI, the first leak and now this one seem to be the result of the hose coming in contact with part of the tub. The slight vibrations has caused it to rub and form a hole. At least thats what it looks like to me

Called Strong this morning, I had emailed them pictures yesterday of the leak. The are sending me the parts to fix it, should be simple enough. I'm still under parts warranty

Are those piped ribbed or just colored in stripes?  If it's not ribbed, I'd just wrap it in silicone tape and be done.
