I have a 1986 Omc4.3 v-6 from a cobra setup. And i have a 1984 Chriscraft Scorpion with an 800 drive and had a 5.0 v-8. I would like to install the 4.3 in that boat. Will the cobra manifolds match up to the exhaust tubes on the 800? Any other info on this swap would be helpful. Can and can'ts, do's and don'ts?

Nope,... While Anything is Possible,.. That won't be an Easy swap...

The outdrive upper would also have to be changed as the gear ratios are different between a V-6 and V-8.
