I just bought a 1985 Thundercraft boat on ebay, sight unseen. I picked it up yesterday and towed it to inside storage until the weather breaks. Unfortunatly, the storage area is 2 hours from home [but free and secure].<br /><br />According to the previous owner, he used the boat 2 years ago and it ran fine. He said it needs some electrical work [probably within my scope].<br /><br />The boat has been stored outside and uncovered. It has sustained a substantial amount of water and sun damage. The deck feels soggy, the seats all crack when you sit or stand on them. All of the upholstery needs to be replaced.<br /><br />The boat has an inboard engine that has been pretty much protected by the engine cover. The hull is fiberglass, so I am hoping that the water and sun exposure are not an issue [except for the fading].<br /><br />Before I get into any of the interior problems, I want to check the engine. I'd also like to check the lower unit.<br /><br />My questions are:<br />1] I couldn't get the engine cover off before I stored it. I only found one latch - on top, but freeing that latch still wouldn't allow me into the compartment. Anyone know what I might be missing? As I indicated, it is an inboard engine. The boat's markings are a crest with the words 25th anniversary - is there any way to determine from this information what the engine is?<br />2] Before I do anything, is there a procedure I should follow before cranking the engine?<br />3] Can an inboard engine be run for one or two minutes without water, like a car engine can?<br />4] Where can I find a manual on this boat? My searches for Thundercraft only bring up other boats for sale.<br />5] The interior is going to cost a mint to replace/repair. Any suggestions? I can get back to back seats for <$200 each, and I'll need two. There are also two seats in the back, on either side of the engine cover that are essentially a back to back seat, cut in half. But, how do I handle re-framing and re-upholstering the engine cover and the cushions and the seats in the bow of the boat?<br /><br />This is going to be a lot of work. If the previous owner was on the up and up, I figure I can go up to $2000 in repairs before I start regretting my decision.<br /><br />Thanks for your input. Thank you to iboats - for the service [I had a purchase problem last year] and the resources.<br /><br />p.s. - no expert, that's for sure. The dg-newboater name was established 3 years [3 boats] ago [darn, boating is addicting).

Re: Thundercraft boat

Well, I'll Try......<br /><br />1) You'll have to figure out How to Open the hatch......... Hammer,+ Wrecking Bar, Maybe...???? :D <br />Once it's open, Then you can ID the motor/drive...<br /><br />2) There are Many opinions on this 1..<br />If it were Me, I'd check the fluids, pull the coil wire,+ Crank it,while spraying Atleast a 1/2 can of WD-40 or something down the carb.,+ check for Oil Pressure.......<br />Then hook up the coil wire, Recheck the fluids, attach a supply of Fresh Gas, check for fuel flow,+ See If She'll Light........<br /><br />3) Sure, But, You'll Smoke the Impeller........<br />BTW, 1 minute is a Long Time, 2 is an Eternity....<br /><br />4) You're Not going to find a manual for the Boat....<br />You Need a manual for the Engine,+ Drive.... but, You need to Identify them 1st......<br /><br />5) You'll need to get Creative here.... Calling a few local Upholstry Shops in your area will give you an Idea......(I see All of your budget getting lost here)<br />Or, Learn how to do it Yourself.........<br /><br />Once you have the boat opened up. an Icepick will be able to tell you How Much fiberglass,+ wood work you'll be doing..........<br /><br />Skip on over to the Project Boats forum.... Several of the Guys have photos,+ ideas there....

Re: Thundercraft boat

You state that the deck feels soggy. The hull may be fiberglass, but the floor, stringers, and transom are most likely wood. You'll want to do a thorough inspection of these structure before you invest any money in cosmetics like seats. I'd certainly make sure it runs before I went any further. If you have engine trouble and/or wood rot, it may be a bust. Check the project forum and search under "wood rot". If it's not rude to ask, what is your investment so far? Good luck.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=31270&item=2465698842 <br /><br />$640<br /><br />Could turn out to be a deal. The trick is to diagnose the problem areas before you spend much money on the rig. Worst case senario, you can part out the motor, outdrive, and trailer, and get your money back.<br /><br />Keep us up to date on this one, it sounds like it could turn out ok. Don't be afraid to ask more questions.

Re: Thundercraft boat

Bondo - you say an icepick will tell me how much fiberglass / woodwork I'll have. I thought the fiberglass would hold up to the abuse of waterlogging - am I wrong?<br /><br />I can replace all the wood without being to bothered, treated lumber isn't to terrible to deal with, but I'm nervous about having to do fiberglass work.<br /><br />rosco - you knew the price. Were you bidding?<br /><br />Thanks for all the feedback, I know the motor is 1st agenda. On my outboard I would hook a hose up to a device that cups around the lower unit. Is the same true on this motor (for cooling)?

Re: Thundercraft boat

The Fiberglass holds up Just Fine.......<br />It's the Wood that it's Wrapped Around that'll turn to Dust..........<br /><br />If the Stringers Feel Good under the Thumb,<br />Drive an Icepick into it....(the Stringer, Not the Thumb)<br />If it's Rotten, You'll Know........<br /><br />It appears to Me,<br />You're going to be spending Alot of time down at the Project Boat Forum......... :D

Re: Thundercraft boat

No dg, I wasn't bidding. But you said you bought it on ebay. I just did a search for "1985 Thundercraft" and checked the completed auctions. Presto!!! Up popped the listing.

Re: Thundercraft boat

Well, I got a chance to go look at the boat a little closer, and I have posted a bunch of pictures at Thundercraft boat.<br /><br />I didn't start the engine. I have to address some wiring issues first, before I feel confident swapping the battery and putting power to the system. I noticed a small melted ground wire, so I want to investigate that first. Any ideas on where I might find a wiring schematic? The cabling all looks to be original.<br /><br />I visited the project boats area and saw the work that other owners did to fiberglass boats. Far more work than I'm wanting to get into. The stringers feel strong, but it's soft between them. The white coated wood that the seats were bolted to are still solid. Any suggestions? I was thinking I should cut out a section of the floor and peek inside, but I hate to compromise the deck, it appears to be continuous. I don't see how, if I removed the bumper guard, I could get the the upper portion of the boat off. Any suggestions on where I can find more info on how this boat was made?<br /><br />The motor LOOKS good, the trailer is crap! The power unit has a ton of pitting. Is this a concern?<br /><br />I would appreciate any input - will keep you updated as it goes along. May be a long process, as I don't currently have a good, convienent workspace and need to focus on getting the 1st boat (I have a 15' aluminum with a 75hp outboard) ready for this season.<br /><br />Speaking of which, a big concern is getting the aluminum boat painted. I am thinking of using the beam of the building to lift the boat for the task. I'm sure the beam can handle the weight. I've read about painting and think I'm ready to tackle the job (I'll just be prepping and adding another coat). Again, open for suggestions.<br /><br />Thanks

Re: Thundercraft boat

I'd try to get it going mechanically and see how the boat runs before doing anything else. If its mechanically sound, you can then decide if its worth bothering with the flooring and stringers. And then maybe the upholstery. Upholstering can cost you a bundle if you have to have it done.<br /><br />The engine LOOKS impeccable! ;) Soon you will see if it's WORTH anything! :D

Re: Thundercraft boat

Not to dig up a corpse, but do you have any pictures of your boat? It sounds like the same boat I have and I would like to get some good pictures of the emblems on the side. I am having no luck finding badges for the boat and have a new addiction. This winter will hopefully allow me to reupholster the seats and rebuild many of the components (Something new to learn) Thanks for any help!
