Hi All,
New to the forum, and about to completely tear down and rebuild a 90HP 1991 Force OB (906F91A) - both the powerhead and lower unit. My question: what 'special tools' are absolutely necessary and why?
Some background: compression-tested the cylinders and got 100-70-70. Oil drain on lower unit produced a drip of light brown sludge. Looking at this project as a challenge - it was my grandmother's boat, who has passed, and has been sitting up for > 7 years. Would be really cool to restore.
Looking for people who have actually worked on these motors to give some friendly advice. Thanks in advance.
