i have a 5.7 / 21'-00" donzi with a cobra outdrive. i want to change the outdrive. I hear volvo and mercruiser have aftermarket toys. Has anyone gone thru this? By the way, South Carolina is going to the college world series again.

SEI is the only aftermarket company that makes a conversion kit for replacing a cobra drive with a Mercruiser.

Volvo made some of the later Cobra drives, however, so it's possible the Cobra is actually a Volvo & not an OMC. Don S knows more about this than me.

Just pull all the OMC junk out of the boat and find yourself a 454 and Bravo to bolt in it's place.

That's what I did.

Rick-

You would recommend a 454 in a 12' john-boat!

Hey, not a bad idea!

I have been looking for quite some time. they're pretty hard to find (cheap)


I think a 454 can be built to make a LOT of power though....
