Verify you have good compression on each cylinder. Not sure what yours
will read as not sure of brand and year. However, each cylinder should be 90
psi or better and all should be within 10 psi of each other.


Tony, I will do as you suggested. The engine is a 1994 Tohatsu 90HP. Any
idea what would be an acceptable compression on this specific outboard?
Once again, thank you all for your help.
