Today I missed a channel and ran aground stuck on mud. The prop that churning before I actually realised I was stuck.<br />After I was free, I noticed the motor a little lumpy.<br />My worry is that some of this mud silt has entered the water jacket around the cyls.<br /> I flushed it on muffs for about 15 mins when I got home. Plenty water coming out of telltale ( pee hole)<br />Can I back flush the motor if I remove the leg and shove a hose up the water pipes.<br /> I am just worried that silt/mud might be in the water jackets?<br />It's a Classic 50 inline 4cyl 1986 model
