I believe it my boat runs high 50's with the same engines and a lot more weight and wind drag. must get 3+ mpg going 50!

Are you guys forgetting about the big Magnum's with diesel out there

I've been looking at ads for them. What does yours have in it?

Mine has 1200hp MTU'S with #12 Arneson surface drives swinging 32"- 6 bladed S & S props. cruises at about 50. Not bad for a boat that weigh's 56k lbs

I'm looking to up the HP to twin 1550's if I can find the right pair

That's awesome. When did they switch from Detroit 2 strokes?

MTU'S were an upgrade option on the Magnum's back then. I contacted Magnum when I got the boat and they sent me the original build sheet, pictures and spec on the boat.

If someone is looking to repower their boat to diesel?

Have a look, looks like a cheap way to get started
