[QUOTE="Pappy, post: 394190, member: 3278"] By all means! [b]Before you run it[/b] the high speed jets need to be checked and verified that they are the correct ones for sea level operation. Go to marineengine.com and look up your engine by model number and year and check them, If you need help we can help you here. If you are running the correct jets for 5000' there is a good chance you will stick pistons at sea level. Since it was purchased in 1987 am not sure whether the engine would be an older or newer one. If it is a 56 cu.in. block those are more sensitive than the older 49 cu.in. blocks. The changeover years started around 1986. [/QUOTE]
