Why is 200 hp a bit much for Vs ?

Curious about perfomance characteristics with a 200hp, assuming 2 stroke so weight not the issue.

I've read some threads suggesting 150/175hp " perfect" while 200 hp a bit much.

Why ? Does the boat tend to porpoise at high speed with a 200hp ? ( bow go up and down continually )
Is it a weight issue ?
Does the stern dig in too deep when lifting up onto plane ?

Appreciate some feedback, thanks
 
Pretty much boils down to a 175 will push you almost as fast as a 200 will. Once you go above 175HP you really don't see a big gain in performace as a 175 can push the boat about as fast as the hull was designed to go.
 
They handle a 200 2 stroke just fine, they say a 150n is best all around due to overall balance of the hull and mostly because you get great fuel economy and great performance out of one.
These hulls do not need max power to perform very well and carry a substantial load.
 
I'm running a 200 Merc and my V performs GREAT( zero porpoise, stern does not dig in at all)....I've seen 53 mph on GPS. Im sure they run great with a 150, but I would LOVE to hang a Yammie 250 2 stroke V-Max on the back!
 
You know I like fast but the opportunities to go fast are few and far between. I third or fourth Willy & FERM. Additionally I think a lightweight 4-stroke would be a strong consideration for me.
 
Yeah I get your point Ridge...Im lucky where I live(Lower Chesapeake) if the weather is good, I can run WOT as long as the engine and my wallet can stand it!
 
friend of mine had his v out Sat for the first time and the motor first time since my rebuild and it ran great numbers no porpoise at all your motor isn't set right on your transom then it is to deep most likely. his has a 200 evinrude and it ran out with 15 x 17 ss prop 5500 rpm @ 49 mph and 2 adults 3 grade school kids.

Hey Skool, Im so used to running Makos that tend to have some porpoise when trimmed all the way...I cant get my V to porpoise even if I try.....to me I need to get the bow up a little more. I have studied the motor height and had my engine builder look at it also(He races outboards) and it looks perfect. I think next time she is on the trailer I may raise it a notch.....may take an hour or so....just to see what happens
 
Oh and the batteries are up in the console.....What do yall think....will raising the motor actually get my bow higher?



SORRY FOR THE HIJACK!!!

yeah it should um you need a long straight edge to put on the bottom of the hull to the motor then trim the motor as low as it will go and see where your straight edge hits the lower unit. it should be 1 inch above the trim plate on the foot. at the back closest to the transom.
 
IMO 200 is the perfect HP for most 20' hulls, V20s included...it's amatter of WHICH 200HP you select...so far, I haven;t seen a better match for the V20 than a small-block 200HP Etec...I think Lumberslinger will agree...

If I had to pick 4-stroke power for a V20, right now it'd be a 175 Zuke...and that's only because Honda doesn't make a 175...
 
I agree with Reel too.
Draglink, I found that to get the bow to fly setback and prop choice tends to help. Trying to be a voice of reason here. I see your V-max and raise you a 300xs. Just not sure how the old girl will react.. Still playing with it.(and the boat too) :sun: BGREEN has created a monster, they were never designed to go real fast. Nobody has come forth to say they found the speed at which the boat becomes unstable/unsafe.
BTW- with that crew you had aboard last weekend, it ain't gonna go too fast, nor get the bow to fly without some serious hp. Any captain worth his salt would trade speed for some PYT with glow sticks all day long.
 
Hum.........for maximum " realistic" speed - meaning engine that's not too heavy........
I'd agree with the small block etec 200 hp.......

I'd also suggest an Optimax 225, prop'd and trimmed just right may push a good V 20/21 to 55-60mph light load.

That's nice speed because when it's truly flat, you could " cruise" at 40 - 45mph.

Nice.

The Optimax is not going to give you 55 to 60mph---besides--you do not want this boat that fast--When I had mine at max around 53 fully trimmed out--it is getting scarey--40 to 45 is real comfy.
The Big 200ho E-Tec is actually 218 at the prop--so a 225 will not do it--LOL.

The reason I said the 175HP E-Tec instead of the 200 Small E-tec--I do not like being at the top of the HP range for any motor. That is why I have the Big 200HO E-Tec.
 
Ridge...aboard your CC w/250 HP I never felt any squirrelyness to the ride at all...I don't really know if you were WOT or what top speed we were runnin, but I know it was FAST...VERY fast...felt stable to me...

Genie, I hear what you mean about being at the top HP range for a given motor...and maybe I am over confident about BRP's engineering capabilities, but I would hang a smallblock 200 Etec on a boat in a heartbeat...I'm pretty sure they wouldn't shoot themselves by going to market w/a fly-apart motor that hasn't been tested extensively...OMC in past days would; they proved that w/the early FICHT and where'd that get 'em...Bombardier has better sense...
 
I have a good friend with a '74 center console V that he totally rebuilt with composite stringers, floor and transom...she is a lot lighter now. He went with the E-Tech 200SB. He easily sees 55+ and at cruising speed she almost makes fuel!

Mine at 53 was very comfortable, wasnt squirrely at all

She really is nice cruising at 40, but usually keep her around 35-37 range to save a little fuel and keep my crew happy
 
Never wide open on our trips Reel. Besides, it won't achieve breakneck speed with the 23P prop until you lighten the load. Heavy load I see mid 50's Summer prop is a 21p Lightning that is close to the Mirage prop. Better mileage and tops out in the high 50's but is a better all round prop for fishing and cruising with a little more snap out of the hole. The 225 Optimax is pretty strong Genie Aye, I have a friend that replaced his twin 250's EFI with twin Optimax 225's with the same lower unit gears and he ran out of prop. I am not disputing the prowess of the 200 HO, I would take that in a heartbeat. Perhaps the difference lies in the center console versus cuddy on MPH?
Porpoise is non existent with normal trim angles, even with 30" setback. And I think the 250 is pushing 500 lbs.
