I used a marine style(Mercruiser)remote housing, and modified the braided stainless lines from the outdrive tilt hydraulics to install a spin on unit for my 235. It uses a standard #5 spin on cannister. I made certain that the lines going in AND out had a 1/8" restriction to maintain oil pressure where it is supposed to be. Pics are posted at www.picturetrail.com/yachtcare I'm in the group that believes some oil filtration is better than none.
