Hi all; I have a few more questions about converting a 9.9 to a 15 . I just rebuilt my evinrude 9.9, and I've found a 15 hp carb. I thought my motor was a 1990 when I posed my other questions on whether just using the bigger carb. and found out for a 90 to 92 it would as they have the same exhaust tube round on the bottom end. But since have found out my motor is a 1989 and the exhaust tube is square on the end with a gasket.
My questions are
1 - Will the square tube be sufficient to get rid of the exhaust if I install the 15hp carb.
2 - If not and I have to change to the rounded end tube of the newer model will the outer exhaust housing of my 1889 9.9 be ok, or would I have to get one of the newer models as well.
I'd really appreciate an answer of some kind as I'm anxious to get a new carb on the motor whether it be the 15 or getting another 9.9 carb motor. as the old one is cracked. Thanks ...Plmbr
