Hope to run with you guys some day.

Since this turned into a bit of a boat thread vs an engine thread - more specifically a 27-29 ft boat thread - I have a 27ft boat myself......

We rebuilt a 272 a few years ago for a customer. Whippled 383's making 550 HP, Bravo drives and hydraulic steering. It ran low 80's with ease in the summer heat.

That's a nice boat Dave.

That much nicer than my bottom feeder boat, I love it Uncle Dave. Here is my 27-4=23 footer (or 27-5=22 depending on which measurement :) ).

A roughly 28 ft boat (give or take a swimstep) with "about" 850 HP runs 69MPH?

How much fuel does it carry, and what does it weigh?

Uncle Dave

Thats all I could get out of her @ 5600 with 23 3 blades, The 272's have a bad hook in them to help them get up with small power (350 mag ) . Ours with 350 mag power would only run 54 on GPS. With the 383's 69.7 on GPS all day top 71 best day thats picking up 14 mph from the 350 mag's. Mopower put 540's with 625hp and got it up to the low 80's. The drives are deep on these boats but they ride good. Do a search 272 thread lots of info in it !!!!!

Thats a pretty big jump in prop. What RPM do you turn with the 25's?

Thanks for the likes guys.

I havent met many boats I dont like, and Id like to spend a day in any of the boats in this thread.

I was meeting a group of guys with similar boats and one guy says- I wonder where all the poor people are today? - another guy in our group answers - they are all right here!


69 Miles an hour in the ocean is hauling A. Once you get past 55-60 MPH the crowd thins out at 70 it thins out a lot.
