I had an '86 F3LS and an '87 242 LS. Both had the "350 MAG" Alpha One package and the F3LS (21'6") went about 40mph max, and the 242 could barely make 37-38 mph despite several prop changes. Actually I did get over 40 in it with a clever prop as it was sold to me but getting up out of the hole was horrible with that prop.

That was not very impressiv Beak...

Though the one I am considering is 454 330 hp

And I am told it goes 53 miles

No, it wasn't, and that's the main reason we sold it. The 242 is greatly underpowered with a small block.

Well then it is good that the one I am considering has a big block.

I was infact impressed with the top speed of my old 1987 26scarab exel 54 with a 350 mag even though it took some time to reach it. *S*

Great riding boats. you are correct on the speed 3-4 mph faster for the LS. You will need big power to get it over 60mph.

Nice LS Masi242

Thanks, we like her, but wife wants a bowrider

Ok Thought I jump in, you guys are right 53' top out .. full tank of gas [700lb ] and all our stuff about [300lb ] plus the thunder exhaust = 53 but what a great ride. It has a 454 330 hp bravo 1 with 1.50 gears with a 21 mirage prop, I love this boat runs perfect summer long.

Don you dont have a mag? does yours have bolsters?

How mouch more speed in saltwater then in freshwater??
