What is the top end on the 235+ on the HydraSport?

I'm swinging a 15 1/2" prop, but I've hit 53 with 2 people and a half tank of fuel while sucking down close to 28 GPH. Once you port a big looper a little bit they can go through some fuel. I an't complain though as I can cruise it at 3800 running 21-23 knots burning roughly 10-11 GPH, not to mention the power that she has to get on plane. I'm sure I could get it to almost 55 with a better prop, but the HYDRA-SPORTS 2000CC was never meant to break 50, it has a hook in the transom that acts like trim tabs and it plants the bow around 45 hard and takes ALOT of engine trim to break it free.

I hear you. I have seen a major increase in speed before with a engine swap similar to the one I have done here. But the hulls were different.
The 250 EFI has a lot more torque than the old 2.4. I suspect that you, of all people, know about torque.. The fuel burn on the EFI is 30 or 32GPH. ONE hour of WOT and turn back to the marina... LOL
Just for kicks and since this ain't going as well as planned I will kick you in for mid-30's and also 53MPH. If you win you have to take me to dinner with the Gift Card..

Folks it ain't going to cost you nothin to reply. I am kicking in the dough and a gift card or whatever.

MJ -- Bad idea?

Thanks for your cooperation..

So far we have 35,52.8,53,54 MPH

In the Guess the top end Contest. 20v CC 250EFI Merc on Bracket-How Fast? I'm kicking $100 to the fundraiser and $50 to the forum member closest to the actual MPH. If you don't reply you can't win.

I'm going to have to say 56mph, trimmed out balls to the wall.

I'll be the optimist and say 59, if you can't get it to run that fast, then let me drive

I was told by a trusted source(who knows) that the 200HO actual builds closer to 238hp. Does not make sense to me to sell as a 200--But I know that it was alot lighter than a 4 stroke.

And at that speed--personally--it is feeling a bit light.

It is real comfortable in the 40's--but over 50 and it is to light feeling.


I will through in 58.2

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...

All I can say is...VIDEO!!...

I guess I'll go for 54-55 since this baby got 56. http://orlando.craigslist.org/boa/1341039507.html Same basic hull as the V-20 and it's a CC, although that 300XP is pushing 300+HP to the prop easily.

Thanks for all the input. Going to the lake now for a marathon break-in session. Try to post a pic.
