My early 70's 9.8 HP had a water circulation problem - no water from peep hole near cowling - and it turned out to be the rubber linkage hose between the copper tube and the impeller outlet. Put in a new hose, all fine, water out the peep and all. Ran fine for 3 hours trolling, then squeaked for 1-2 seconds and seized up. I am meticulous on oil/fuel mix (50:1, using 3 oz per gallon to be sure). Any ideas? Can the lower unit freeze up and cause a similar condition? Searching for what to do first?
