The V 20 hits 50mph tops, but any faster ?

[bgreene]

Fifty miles per hr is plenty of speed, but anyone ever find a way to run one of these much faster ? Say 60 mph ?

Come on you V20 " purists" ...........live a little !!

Let's wait to hear what Craigan's top speed will be with my old V (dually) and the 225 on that bracket... I bet she'll fly.

never 60 but on a smooth day out of the river i hit 53.3 on the gps !!!!!!! felt very fast and smooth !!!!!!! .....I only went straight , no turns !

I've had my HYDRA-SPORTS that fast with my 225(or at least that's what the cowling says), and it weighs about 800 pounds more in just hull weight. I believe 60 is possible, but the deep vee hull has drawbacks at those speeds. A deep vee hull will continue to climb up the faster you go so there is less boat in the water the faster you push her. The problem lies in the fact that at a certain speed there is so little of the boat hull in the water that she eventually becomes very unstable.

I have pushed the limit with my 225 Yamaha once or twice and it ran up to 54 mph, by gps, however it was not very reassuring the way the boat felt under me....It felt like at any minute it would lose control...much more stable around the 40 mph range.....

im sure a single 300x on a adj jackplate with it propped out for top end would run 60. strong engine. i think though that going over 65 with out any serious amount of hp would not be possible.

[kraken]

are all of you guys running outboards only? I havent got mine into the water yet but the engine is the merc 470 with 170 hp. Seems that motor would push a 20 footer a bit faster than 55.

I ain't affraid.
I have a 2.4L Merc 200 pushing 48mph on a bracket. The boat is heavy for a lot of speed but she feels great. Turns are not a problem at 48 she still has some edges in the water. In a few weeks my CC gets a 3.0L 250EFI. I won't know top end for a few weeks (break-in) but I think it might be close to 60. I did a similar swap on a 22 Pursuit Cuddy and went from 41 to 55mph. Doing it to cruise 40 at about 4000 rpm.
My 20 has some hook built into the chines, all of them probably do. I removed about 50% when the hull was flipped and spent countless hours blocking and sanding. I would guess the round keel at the stern will probably give a bit of chine walk at ??? speed. With no real pad to run on I don't really know. Maybe it will rise to the innermost chines and just fly.
These boats sold, virtually unchanged, for how many years? The reason is that they handle water better than most, everyone love the lines and they offer good versatility.IMO
A 300xThat would be cool. You could never be accused of underpowering. Boat Insurance? Call Lords of London...

i can promise you that 470 wont get you past 55. on radar or gps.

and about the v-20 chine walking, it would probably ride like a checkmate or a baja (if im thinking of the older 80's v hull ski boats) where was it feels like the front end is hanging out there and it will rock but not too bad. not if the weight dist is all messed up then who knows. maybe a up and a hard roll to the right.

Hope not. It would be a shame to come this far with this project to see it spread all over terrebonne bay. (Captain included) Baby steps.. but that image will be burned into my mind from here on. Thanks
