Has anyone tried it?

been done years ago....there were a few of them running around with 200s and 225s on em....i dont think they set any major speed records but the accelerated like rockets....

I wanted to upgrade to a 300xs but a buddy asked why don't i just bolt the spare motor up as well. I would like to hear more about the step.

dirk pitt on s&f is the one to talk to about this, he had one. also t2x on here and s&f but he does not like supers

Dirk also had twin 300, so yes it can be done!

not on a 21, you been snffen resn again?

you know what you are right, he had 225s I think.

I was getting mixed up because he got one engine off a another boat that had twin 300 mariners, he got one and ed got one.

But hey why not 300s, go big or go home!

Nice, Hmmm, Maybe thats what I need on my 21 Apache
