Top Speed??

[bigshrimpin]

What is everyone seeing for performance numbers . . top speed . . . cruising speed . . . fuel consumption @ cruising, etc. ?

My V20 center console with a 150 Yamaha tops out at right around 37 mph at 5000 rpm. I'm going to be looking into the prop to make sure I've got the right one because I should be turning a litlle higher top end than that. Also have to make sure the tach is reading correctly. Cruise speed at 4000rpm is right around 28 mph. I haven't got a feel for fuel consumption yet. Once I get things dialed in correctly, I'll get a reading on that as well. But, so far, I'm real pleased with the performance and fuel consumption based on the amount used vs. speed and distance travelled. Seems to be fairly economical relative to what I've owned for boats in the past.

Chumbucket , I have a V20 C.C. with a 150 yamaha as well . It will turn 5250 rpm. The speedometer tells my that I am doing 42-44 mph depending on the load. I had it out yesterday for the first time this year . If these gas prices don't come down , I will see very little of that 5250 range this year . $1.959 @ Wrightsville Beach , NC

>:( I'd hate to see what dock prices will be this year! I'll be trailering my boat this year anyways. We're at $1.65 on the street pumps here in Mass right now.
What year is your V20 Fisherman? Any modifications to the layout? I'm always interested in other peoples ideas as well.

I have a 1994 , the last year for the center console . It is almost a tough mounting the electronics on this modelas the steplift . The console does not have as much mounting space as my friends 1986 cc. It also seems a little lower . When I bought the boat last year it had a small Apellco loran and a Hummingbird fish finder. I am thinking about taking those off and installing one of the new color gps/sounder combos . That should free up a little space as well as giving me a much better fish finder . Other than a tight space console I love the boat . I had a 17' Whaler before the V20 and I out grew all of that pounding ! My family had a 1974 Steplift that I grew up with . We were on the third motor when my dad sold it. I looked for almost a year to find my current boat . I found it in Ft Walton Beach Fl. The boat could pass for 2 years old . It is just warming up here in NC and I plan to get to work on it soon .

Hey Guys,

Performance stuff on the V-20..

I have a 1987 V-20 CC with a 200 HP Suzuki EFI & a T-top. I am still trying to get the right prop after adding the top. Before the top I was turning 5200ish RPM and getting upto 53 MPH. I am now turning 4800ish and in the 45 MPH. You guys are right about this season and expected gas prices!! There will be a tight eye on the RPMs for sure!

Great site!

:P

I finally got my 1991 V-20 CC on the water last thursday at a local lake. Just wanted to check out all systems before heading offshore.
Max speed with 1992 200 hp Yamaha was 48.9 on GPS at 5300 RPM. No T-top 1/2 tank of fuel 1 person.
Boat handled great but really needs hydraulic steering. I could trim engine untill it was nuetral steering. I just prefer not to have any torque steer.
I am installing a Navman Fuel flow system today. I will post all performance and fuel consumption numbers next week some time.
After reading directions it looks very easy.
Ordered T-top/leaning post last friday. Will take one to two months before intall is done. Just before tuna season I hope.

Has anyone installed an additional fuel tank inside the console yet??

Not sure if I am going to do this yet. Want to get fuel numbers first. I would like to get a 200 mile range if possible.

Just finished my conversion of a 1974 V20. It now has a 175 hp Yamaha. I have two 20 gal gas tanks in the sides. I don't know how this system is going to work but will post when I get in the water.
What size props are you guys using?? I was using a 17 pitch when it was a I/O. I have gone to michagain site and sized the prop there and they say I need to use a 15 pitch?? The motor I bought came with a nice SS 19 pitch. But I don't think it will do well. I will try it and see.
With the I/O set up I use to get just about 30 mph with full tanks and 2 people. and about 3 1/2 miles per gal. I am sure that I will use more gas now that I have a outboard.

MJ, Try the 19 pitch prop before buying anything new. Most of the Yammis use either a 17 or 19 pitch prop. I would try the 19 first and if you're close to 5200 or better, stay with it. If you only need a couple hundred more RPM's, then try a 17. If you think you do need a 17 pitch, let me know before you buy one. I think I've got an extra laying around. It's not the best but it would certainly tell you if it would work or not.

Thanks alot chumbucket. I hope to do a water test by the end of the week, if the weather lets me. I was going to try to stay with the 19 anyway, if it worked.
