I have a 1979 V20 CC fisherman that I am putting a 140 Suzuki on.
Is anyone else on the board running the same engine?

Welcome to the board...yeah we've had a couple of guys hang on a Suzy 140 ...w/ good result...performance won't be ''BLISTERING" (neither is my 150), but it'll do a good job and should be very econimical...propping will be very important ;) (but what boat isn't?)...
Post some pics as ya go along...we likes 'em!! ;D ...

Thank You.
This boat is not very photogenic; many folks around here would have dumped it, rather than repower it. But the boat is dry and rides well in the local conditions.
I am a retired commercial fisherman, so my boats do not have to look perfect, just perform perfectly. This is one of those ugly duckling boats that fills the bill.
This Board has been a big help so far, I congratulate you all for it.

ran into an older gent about 2 months back launching a v20, I think it was a 1979 and he was the original owner. He just re powered w/a suzi 140 so I had a couple of questions for him. I first asked him how he liked his boat and his response was," I go everywhere in this boat". Then I was looking for some comments about the motor....." It's good", was about all I could get out of him.....He was sorta a crusty old man so it was tough to engage him in conversation. I waited around [mostly in an awkward silence] because I wanted to hear him start 'er up.....which he finally did......it sounded smooth as silk and as quiet as a mouse. As he pulled away from the dock I wished him good luck and he just kinda nodded back to me.....I did not even bother telling him about WellcraftV20.com :-/

Well, I'll have to wait to hear my new one, Ernesto has added a few days to the time line. Its on, but not wired in yet. Today was a washout with rain all afternoon.
I have not heard a disparaging word, yet. It should have the same performance as the V6 Johnson (155hp) that came off. And its a hundred pounds lighter. With people, coolers and gear the V20 is not a lightweight. Twenty knots is plenty fast so I think I am doing the right thing. The quiet will be nice too.
Lobster season is just getting rolling here, so it is a bad time to be boatless. I was lucky enough to find my local guy had a couple leftovers for sale cheap, and I bought one.

I have an '89 Cuddy with the Suzuki DF140. The motor runs great. It's plenty fast for me and it sips gas. I think it's as good a match as you'll find.
Just be careful if you got the 3 year extended warranty. It seems that they set it up so that it's very difficult to comply with all of their requirements to keep the warranty valid. It may have just been the company Suzuki was using (GE).
I bought my Suzuki with about 100 hours and it has performed flawlessly. I just recently bought a brand new 90 hp Yamaha for my wife's bought (17' Whaler Montauk) which also runs great. I'd say the Suzuki is just a little bit quieter and smoother at idle though.
Good Luck with it.

Well Reel, your right I am a lucky guy.
I live on the sail boat here in Marathon, when I am not sailing.
The dinghy just does not cut the local conditions, and if you ever caught a kingfish in an inflatable boat you know what I mean. It becomes a deflatable quickly. The V20 is not 'the' tender, but one of them.
A kid in Key West had this boat for sale for a while, but every time I tried to look at it the price went up. Finally he ran it aground and packed the motor with white clay mud and cooked it. He called me the next day and told me he needed money and he really needed to sell the boat. He put a new waterpump in the old Johnson and I was dumb enough to buy it. To its credit the Johnson ran for a while, then one day started puking what looked like vanilla milkshake. Rest is soon to be history.
RIB, no extended warrenty on this motor as it is a leftover 2005, with a discount. I did my home work, and I am happy you all confrimed that what I thought is OK. Quiet and vibrationless efficiency beats speed any day. Thanks.

Update. With two hours into the breakin period, stats are:
2000rpm=6.8kt
3000rpm=10 to 11kts
4000rpm=18.8 kts
Conditions were flat to three feet. In the 1 to 3s speed fell off at 4000rpm to 17.5.
There was about 25-30 gallons of premix left in the tank, dealer said it would not hurt it, and it runs find.

Hey Snoozer...
Quickie on trim:
Outta the hole w/ trim all the way down; best bite
Once gettin' on plane, hold up button for a slow 3-count(1001, 1002, 1003), maybe 4 depending on how fast your trim moves
Steering will be heavy on plane w/ trim down; will lighten up w/ trim up; RPMs will increase 2-4 notches
Goin' straight and long turns, leave trim up; best performance and fuel econ.
Tight turns, trim down, best bite, prevents "blow-out"
Rough seas, you want the bow down, so trim down...if ya wanna get real fancy, trim tabs will help here, too among other things...wish I had 'em...
Anyway, hope this helps... ;) ;D...

Reel, there seems to be plenty. You have to measure fifty to find a keeper in some places. There is a lot of predation also this year, or it may be that we have not had a 'cane to wash away the detritus. It looks like Nurse sharks like lobster as much as we do. And they tend to go after the bigger ones. I don't know how the commercial catch is this year so far, but the price is up.
We seldom get our limit, it is an excuse to go. And if this motor continues to be this good on gas, I'll be going farther into the back country, on more like exploring missions.
Edited for spelling.

Predation, in this instance is refering to the Lobsters being prayed upon by other critters.
Detritus, (my spelling has never been great) is refering to the pieces of eaten lobsters (shells) littering the bottom in places where lobsters used to be.

Snoozer: is there any further updates as to your break in progress. I am waiting to see how well it does at WOT. :D
snoozer
10-27-2006, 12:17 PM
Well, let me tell you, I'm as happy as a two dicked dog.
I have not had it WOT yet and may never feel the need to go that fast. In flat water it will fun 28Knt at five thousand rpm. My normal cruising RPM is 4200-4400, at something like 20Kts. (by GPS) There is usually a full tank and a load of something (mostly ****) and two or four people.
The mix of running and trolling, (idleing looking for lobsters) adverages five MPG or a little more. The spects on the motor say it will burn 4+ GPH at 4500 RPM and I think it is spot on. Thats five gal per twenty miles at twenty knots, and I am happy with that after the two strokes in my life.
I have been holding off fixing up the boat somewhat, to see if the combo would be OK. I think its fine, and am getting the cushions redone and sprucing up the boat some. I also bit the bullit for a better sounder to pick fish out of the rocks.
Suzuki's warenty is a mystery. Oil changes have to be Suzuki stuff, and it is pricey. They also require valve checking/adjusting at two hundred hours, an eight hour job for the Suzuki tech. At $110 per hour, its not an inexpensive motor to maintain. I have over 120 hours on it now, so I'll be there soon.
If any problems come up I will post it on the site. For now I am pleased.
Let me add a couple things. The neighbors here call it the 'stealth boat' now because it so quiet. And if I had it to do over, I'd get a 25 inch motor and build up the transom. Way too much water comes over into the well on this boat. And if two people are in the stern, the aft hatch better not leak.
I took twenty pots out last week (all loaded forward of the console) in three footers. Took it slow and had not problems untill I turned around, then got pooped.

In fairness I need to point out that over $750 was tax to Dubya's little brother.
And like most jobs on a boat there was more to it than just hanging the motor and walking away.
New wheel was $350, controls $250, all new cables, hauling & blocking, removing and desposing of the old POS, cleaning up twenty years of several idiot owners wiring, new drain tube, etc. All done in the Keys, where everyone would rather be doing something else.
When I worked, I got paid. I can't expect less from someone who works for me. Having said that, I did think it was pricey.

Your right Joe, and I would be too if I were a teenager again.
But I am on the other side of learning what my time is truely worth. I turn the key and this motor runs, no poking, no prodding, no wondering if it will blow up this trip or next.
I will be the first to admit, I am very lucky to be able to have a new motor. I can also tell you, the time horsing around with an old POS is not where I want to invest the time I have. It is, a matter of priorities. No one wants to spend more than they have to. I never thought I would spend $40,000 on a corvette, but I did once. I have learned a lot since then. I will not loose as much on this motor as I lost on that damn corvette.
The seats are recovered, new fuel sender is in. Time for another round of pictures, .... next time I pull pots.

I dont know about zukies but I see a lot of them and they seem to have an excellent reputation from pretty seasoned captains who are out 250 days a year or more. The sea tow and TowBoat US guys here in Beaufort run the piss out of them and swear by em. On the other hand if the REQUIRED DEALER maintenance is anything like some of the others then it may need a second look..An old guy across the creek asked me to pick up and tow his boat from the dealer as he has trouble backing up his truck( he is 75) and I have to say I was AMAZED at the bill. The motor is a 2004 Yammie 225 and just for an oil change it was $178.00 and I wont tell you what the valve adjustment cost $$$$$$$..I was also amazed to see his warranty book with maintenance receipts for what its cost him so far just to run out a few times a year for flounder. And to add insult to injury the dealer talked him into an extended warranty which DOES NOT cover this kind of ROUTINE maintenance...The motors are not the issue here and can probably get along fine without all the required check ups etc. its the greedy dealers but thats just my opinion...Frank

12-16-2006, 06:15 PM
OK, here's an update. Motor now has 100 hours on it. It has not missed a beat. Fuel consumption is still low and the motor runs easier (picks up rpm quicker).
A note aout the V-20.
It has been blowing like stink for three weeks here in the Keys, and the few crab pots I have must be attended. The V-20 is dryer than I thought it would be. I can always find a speed/direction that gives a smooth ride, and still get to the grounds in a reasionable time. I am pleased. But those of you with V-20s knew these boats are good already.
The only fault is the wash over the stern, and part of that is my fault for not raising the transom befor installing the new motor.
Here in Marathon there is a clean-up going on to get rid of old boats that are abandoned. I have watched two V-20 stuffed into dumpsters and taken to the dump. It is a shame that more folks do not bring back the run-down hulls that are out there. I hear Florida has a new way to get a new title for an abandoned boat and it may be an option.
So this is an indorsment of the V-20 for the Key's waters (and probably anywhere else too).

On the other hand, peace of mind is worth alot and knowing my motor is gonna get me back to port (especially with the wifey on board!)makes it worth spending the money to get something done right.

I never run WOT, because I have to pay to fix it.
The boat will do 20kts at 4200rpm, light.
5000rpm is 26kts, light.
Mileage is still around 5mpg, less if loaded.
By loaded I mean, full fuel, three big coolers of ice, three to four big guys, (I am 375).
The gulf stream is six miles off now, and I troll medium fast.
Lobstering in the gulf is at about six kts.

Well guys the "stream" is 32 miles off today.
I forgot to mention that the boat has a painted bottom and sometimes carries 'stuff' with it. I was surprised how much slime and cridders were riding along last week when I took some folks snorkeling.
Speed is in Knots, measured by gps.
I know I could push it up a bit; but we don't get too many days this time of year for that. The wind has droped out for a few days right now; but it has been blowing for weeks. I usally push the boat as fast as I need to, to get a good ride; sometimes that is less than 2000. Just under 4000 will keep it off plane so I can push through the square chop we get down here; without getting wet.
All said, this motor is a good fit for this boat. If the boat was any heaver or loaded all the time, it would need more hp or a prop reduction. The mileage makes me love it.

In the last spell of good weather, the alarm went off for the 100 hour oil change. So today I changed oil (still very clean) and filter to stay in warrenty. $38 and $20 for the ramp.
Hopefully the weather will back off a bit and it will not take so long to put the next hundred hours on it. The stream is moving off again, but there are still some dolphin around and the crab pots need haulin.

We don't have enough for commercial guys just a few recreational boats. We're going to try to get down to big pine this summer for a couple of weeks and are looking for a house. got any suggestions? The last time we were there we had a house by no name, but i don't think it is still in rental. Glad to hear the new motor is working out . A friend of mine has the same one on a 24 ft carolina skiff and loves it. He has had it about 15 months and has 350 hours on it.

Update.
In the last spell of good weather, the alarm went off for the 100 hour oil change. So today I changed oil (still very clean) and filter to stay in warrenty. $38 and $20 for the ramp.
There are a lot of guys here, including me, that would be ecstatic to have put 100 hrs on their boat during Dec. and Jan.
Keep up the good "work".

Snoozer,
Don't baby that engine too much. Running at WOT allows the engine to properly seat the rings. The engines that come in to my shop with the most problems are engines that are used for a lot of trolling and hardly ever see WOT. All 4 strokes will "make oil" to some degree or another (Yammies, which I absolutely love, are somewhat notorious for that) and engines that are never opened up will make more than those that are run at WOT on a regular basis. I'm not saying to beat the crap out of your engine but don't go the other way either and take it easy thinking that you are being gentle on you engine.
By the way, what prop are you running on that? I just repowered a V20 with a 140 Zuke and I need a good prop stating place.

After running mine, the 14X19 works great and it could use a 14X20 to bring down the rpms a little. *I turned 6400 @ wot, assuming the tach is accurate, recommended is 5800-6200 @ wot. That got me 35 mph GPS measured.

Keep in mind that ALUMINUM props tend to turn more RPM's than STAINLESS props of the same pitch. Aluminum props flex at higher RPM's and lose some pitch.

Maybe I just need a 19 Stainless. Well, I don't need anything, but maybe that's what I'll pick up if I run accross a cheep one.

Diameter and blade style also play a HUGE role. I've run several different 19 pitch props on my COBRA, and all with different results. I've run a 4 blade powertech that was 13 3/8"X19X4 and it hit 5200 with light trim and reached 48MPH(had it up to 5600 with alot of trim but the boat became uncontrollable beyond 53MPH). An aluminum prop that was 13 3/8X19X3 and it would turn right up to the 6100 limiter and only hit 40MPH. I've got a 14X19X3 aluminum that turns 6700RPM's and reach's 45MPH. My current VIPIR now turns 5600RPM's and tops out at 52-53MPH, but it would hit 51-52MPH @6100RPM's(rev limiter is 6100RPM's) before being rebuilt. There is no exact science to picking a prop, but through the dozens(and I do mean dozens) of props I've been through. You can't go wrong with a MICHIGAN MATCH ALUMINUM for all around durability and price.

On my last trip out I was able to run with just me in the boat and about 15 gal. of gas, she hit 40 mph @ around 6500 rpm.......I am just guessing on the rpm cause my tach only goes to 6K.
