One of my co-workers just bought a boat ( http://www.fourwinns.com/line_prod.cfm?fam...boat&model=180H ) that will probably be aroung 4000 lbs. wet on the trailer and needs a used truck to tow it later this spring. A guy down the road from me has a '98 2wd(?) regular cab GMC with the 4.3 6 cylinder. The truck has 190K miles and is for sale for $4500.

 

I think he should keep looking for an OBS extended cab 4wd with a 350. While he's single with a girlfriend, he'll want to be able to carry folks to the lake. Your thoughts?

That may be pushing it a little unless it has the 4.10 rear. The biggest problem you will have is getting the boat out of the water on the trailer. Beyond that, I think the truck will do it. For a boat that size, you really need a V-8 or a 4.10 rear.

I use to have an S-10 with a 4.3 and I use to tow my boat with it. It was close to 2000lbs and did just fine, I also had a transmission cooler put on the truck to help out.

I couldn't really say what another 2000lbs would do, but my S-10 pulled the boat out

of the water, on a fairly steep ramp, with ease.

 

An extended cab truck would probably benefit him better for the future, but it does

depend on what's in his budget.

 

I can't wait to hook up the boat to my new truck and get out on the water again.

 

Let us know what he ends up with.

That boat will only be around 3300# fully fueled and loaded with beer, so the V6 should be OK for short hauls. Think twice if he plans to pull it all over the State, though, at 190K miles, that V6 could be a little tired.

I'd look for a different truck. The OBS trucks were known for intake leaks and crappy brakes. It has way too many miles to be considered reliable towing a boat around. The 4.3 more than likely will have 3.42s or less. The 4.3 in a fullsize truck is probably a stripped down model (who wants to drive a work truck). If it is a 2WD,launching and retrieving may be a handfull.

 

My wife drives a 99' Blazer with the 4.3 and a 3.42 rear end. I towed my Bayliner (21' and 3800lbs) once with her Blazer. I wasn't impressed with the 4.3 at all.

 

Oh yea,$4500 seems a bit much for a fullsize reg-cab truck with a V-6 and almost 200K on it.

You'll be able to tow the boat, but it will be slow going and it will suck gas like you won't believe doing it. I can't answer how it will do on the boat ramp.

 

Plus that seems like an awful lot of money for 98 with 195,000 miles on it.

I agree that $4500.00 seems like alot for the truck it is (plain jane 4.3-2wd)

I too would go with a V8 ext.cab. :banghead:

Thanks for the replys. I agree that he should keep looking. He bought the boat at the Detroit boat show over the weekend and doesn't pick it up until the end of March, so he's got time. He's budgeting $8-9K for a truck and will probably pay cash.

I used my S-10 to tow my boat on this 6 hour drive to the lake and it had problems with

some of the hills. That's the only problem I really had with it though.

All good posts...here's another consideration. 4WD! I was pulling my 19 ft sea ray with a 93 Caprice (5.7 with a towing package) and going down the road it was fine, motor and axle ration was good. However, getting in and out of soupy landings and even the occasional sandy cement landings was a significant challenge. W/O the limited slip diff I would have never made it. I had many opprotunities to bury the rearend at the bottom of the landing! Oh, it was ugly! There were many lakes I had to stay off just because I couldn't be sure I'd get the boat out. Sooooooo.......Using a worn out 2WD V6 may be ok for most landings, a newer 4WD with a 5.3 or 5.7 would be far better.

Keep in mind, the s-10 is half the weight of a full size truck. less weight for the motor to pull on the truck means more weight to pull out back. A s-10 with a v-6 cannot be compared to a c-1500 with the same motor.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
