well i was winterizing my boat yesterday, and began trying to remove the old oil filter. It wouldnt budge...I went to advance auto and got the smallest metal strap filter wrench they had, I broke it trying to remove the filter. I ended up haveing to take the cylanoid off the engine and getting a pipe wrench, yes a monkey wrench to lossen it...so fellas when changing your filter hand tighten then give it and extra 2/3 of a turn and thats all ya need..
