Re: Model 270 Volvo outdrive
RetNav, a vaccum test should reveal any bad seals or gaskets ( as reccomended by the manual). The air fitting screws into the filler hole.<br /><br />I've seen other posts suggesting a pressure test, but over pressurising can cause a leak, so please be careful.<br /><br />I discovered a minor leak in my lower leg using 3 P.S.I. (I used a hand operated bike pump). Good luck.<br /><br />Aldo
