yes get marine grade for sure. probably a good time to replace all the hoses...measure them from the raw water intake all the way through and buy that length from skidim or your local westmarine/etc rather than getting fitted hoses. it's easy to cut them to fit. i also got an extra 3' when i did mine a few seasons ago and use that piece for winterizing and summerizing. it's easier to take the hose off of the trans cooler and put the 3' spare piece on that and in a bucket than to struggle with removing the raw water intake hose from the lowest barbed connection.
