hello new here. i just bought a 78 v-20. i was wondering who had the most weight on the back of their boat and which set up used. i have no engines so im trying to decide which way to power. definately on a bracket. also its was a cuddy that is conv to a cc. thanks

Re: new here
 

Welcome to the site.

I'd say when MJ and CB would stand in the back of MJ's old V, that was the most.

Re: new here
 

i dont know them...but that is funny. yeah my dellima is i need to run 60mi out so i need some desecent speed and two engines in case i loose one i can still run back on one on plane.

Re: new here
 

Welcome to the site.

I can't answer your question on weight, bu tere are many here that can.

A cuddy converted to CC? :o :o :o

You better post pix of that, cause I am sure I am not the only curios V owner.

Re: new here
 

yeah it was a family memeber from whom i bought it. i saw the transformation it was very interesting. the boat was negelcted and is full of leaves. when i get it cleaned up ill make sure to post pics.

Re: new here
 

Skools Out is putting twin 225 OMC's on his V-20.

Someone on here has twins on their V.......who is it boiz?

Re: new here
 

There's an old thread in "Performance" section with a picture of a V with twin 70 h.p. outboards and some discussion of twins. Twin 90's would be sweet.

Re: new here
 

Yamaha has that 90 2stroke motor that looks tiny, a pair of them would do it.

Re: new here
 

yeah that would be nice with two. just concerned about if one went out. i dont think those 3cyl have enough low end. weight is nice 261lbs per.

Re: new here
 

A 200 hp is going to be over 500 pounds, I had a Cuddy 1975 with a bracket and 175 hp. 400 pounds.

Twin 90's or 100's will be fine, and if one went out a single 90 or 100 would get you up to 15 to 20 knots I am sure.

Welcome to the site and lets see the pictures, and were are you located??

Re: new here
 

south louisiana....i wish those were easy and cheap to find like most 150's. thats actually what i was going to try to put on with a bracket that would provide maximum flotation. but if it will sink the boat then i cant have that. ;D

Re: new here
 

My thoughts exactly. PERFECT, PERFECT.
Welcome to the site, POST PICTURES!! ;D ;D
Also list in your profile your location.

Re: new here
 

Welcome to the site...hope ya get her powered up like ya want...keep in mind the fuel you'll need for 60 mi offshore trip...I got lots of faith in these boats, but that's pushin' the envelope pretty wide there IMO...a 2 hr run at 30 mph...make sure there a couple of lightweight fuel-sippers...a pair of my ol 86 150 Rudes woulda never made it ;)

Re: new here
 

I missed that!! 120 mile round trip in a V??
78 V has what a 45 gal tank, maybe a 60? at best you get with one motor 3 miles a gal

Thats 180 miles if you don't move or drift and run back up and the weather doesn't turn and you have to fight the way home,cutting it real close!! And if you have 2 motors I don't care if they are 50 hp your not going to have enough!!

Re: new here
 

You can go the randalman route and get you a 140 JOHNZUKI. It won't be fast, but definately good on fuel. He reports 5 MPG I believe he posted with his 140 at a decent cruise speed. And stock the 76-80 models only had a 45 gallon fuel tank under deck, 81+ upped it to 60 gallons. I know even with my light flats boat, I've got 45 gallons on board and still couldn't pull off 120 miles. My 150 MERC only gets 2.5-2.8 MPG on a 18 FLAT's boat, but then again I got the BIG 150 ;D.

Re: new here
 

Great boats, one of the best designs ever to be put to paper. Never designed to run twins I don't believe. Anything can be done though.
But, just cause it can be done does not make it smart. They are not designed to be long distance deep sea fishing boats. On a good weather window it could be done if you addressed the fuel issue with larger custom tank install or a bladder.
But just a thought, a 30 foot Bertram does not make a good all around in-shore fishing boat, does not profess to be and was not designed to be, the V20 does not profess to be a deep sea long distance possible heavy seas and weather boat, was not designed to be.
JMHO

Re: new here
 

i understand the small tank situation. i often use my dad's v23 dual console and it has 150 yam's with 120 gal of fuel and i would have no problem going 60mi out and then back in.but its a bigger boat with more fuel. i was planning on puttin the extra fuel tank in the cabin, and the batteries oil tank etc in the console to compensate for the extra weight in the rear. the boat at one time did have twin 140's with a bracket and 54 mph on the gps. so that is kinda what im trying to acheive. also here in the gulf the weather is very predictable only have been caught once in 11 years.

Re: new here
 

i plan on building a 80gal fuel tank for the cabin. that should put me at 120 gals.

Re: new here
 

IMO that will be way too much weight up front. When full you are looking at close to 500 lbs.

You need to find out what the fuel burn would be with twin 90hp 3 cyl engines and then figure on how much fuel you will need. 80 gallons of fuel alone at 2mpg would provide 160 mile range. So you might only need 40 more gallons?

What a quandry :-/ I've been on 100 + but not much over 100 mile round trips with my single 150hp and 60 gallons. The most I've burned was around 50 - 55 gallons and that was coming back in Oregon Inlet. I was a little worried with nightfall approaching but at least we had other boats with us. We went past birds diving on boiling fish and I was just too nervous to stop and play.

Re: new here
 

I have a 78 as well, if you lift the gas tank cover that is between
the pilot seat and passanger seat, there is a large open area.
I converted mine into extra storage for anchors.
That would be a great place to put an dextra tank
that would hold about 25 to 30 gallons.

Just a thought.

Re: new here
 

yeah you right about 80 gals. way heavy. like you said probably smaller...60 or 50 gals. in all actuality i can probably put another 40 in the console and have a 20 spare in the cabin if i need it. i'll have a lot of trial and error im sure with this project.

Re: new here
 

i probably could make that work under my console.

Re: new here
 

Oops, that's right you have a cuddy converted to center console.

Re: new here
 

yeah but its a big cc...i would have to look at it again.

Re: new here
 

Ooops I forgot too - duh! You meant in the console not the cuddy. In that case its not as far forward and you should be ok.

Re: new here
 

that my fault my statement was worded oddly. that's what i meant the bigger tank in the console and the smaller backup in the cuddy.

Re: new here
 

I do get 5 mpg (statute) with my single 140 4-stroke. That gives me the range you are looking for with my 40 gal tank (not the original, it was a 60). I also get 40 mph top speed. I never run more that 25-28 in the ocean, even on calm days, it tears up too much stuff.

I could run 60 miles out, but not by myself. Even with twins you run the risk of getting stranded if you go by yourself.

If I were in your shoes, I would get a newer or new 4 stroke 140, 150, or 175, and go with a buddy.

Re: new here
 

....and get sea tow. Really doesn't matter much if you get stranded 20 miles off or 60 miles off.....you are still up the creek without a paddle so to speak.

Get sea tow membership, make sure your radio works, and go fishin! Always better to go it with another boat if possible.

Re: new here
 

One of our members had a V-20 with twin V-4's, maybe 140's. The boat crossed ebay a few times over the past 4 years. Sat real heavy in the stern. If you can find a 2.0 liter Merc 150 you can get around 3.2 mpg cruise, thats what I have and get.

Re: new here
 

Welcome to Do the site, but plese read our Bi-laws. It states that newbies must post tons of pics of their V-20 to satisfy all the other members hear. ;D ;D ;D ;D ::) :P

Re: new here
 

funny. ;D, im going to the other shop tonight to snap some pics. it will be in the dark so i hope the flash will work well enough. should have them posted tomorow.

Re: new here
 

I think cterrebonne bought this boat from Havis. ;)

Re: new here
 

i was comparing weights between the different set ups, i work at a dealership so i have alot of info at my disposal. and engine wise. OMC 60 deg. v-4 are 704 total weight compared to v-6 60 deg at 782 a pair. the v-6 are 78 pounds heavier. i also had some interesting designs on how i would make my bracket to help with the added weight.

Re: new here
 

don't forget weight of props and rigging, not included in specs and you are going to need flotation back there, too much weight

dont laugh.
