I am looking at a ‘98 208. It has a 2017 engine and I was thinking about the gas tank. What was used in that year and what are the odds of it needing replacement?
 
Is it somwhere in the 80g + range? That is going to be aluminum. It's very easy to check by opening sender access.

There's absolutely no way to know if it's due for replacement (or if it already has been) with the info given. It'd just be a wild guess. Talk to the seller and/or inspect it.
 
My 2001 had a plastic tank.
Pop either of the pie plates in the deck area and centerline of the boat to see what the tank is made of.
Plastic tanks can last a long time.

Pop the pie plate and look for a build sticker. My 1997 Islander had an aluminum tank. If it's the original tank it may not be leaking but it's due. You can run a tape measure and feel the edges of the tank to get a size.

Take a look at owners manual on the GW site. It will give you an idea of tank size and location. Look at the boat and see how difficult it would be to get the tank out (under a removable hatch or cut deck and bulkhead. If tank will come out easy it's no big deal.

I have a 98 208 it not aluminum no issues .I did have to replace the transom last year , I would be more concerned with that then the tank.
 
Steve/Seasick... what size was your plastic tank? I "thought" these boats had a pretty large tank which is typically aluminum. But that said, now that I think about it, my last Sea Ray had an 84g gallon tank and it was plastic. So I guess I could be wrong! :)

My 96 Adventure is spec'ed at 82 gallons. Aluminum
 
2001 208 has an 82 galloon plastic tank
 
Hi everyone,

Can someone please tell me if the one indicated is an anti-siphon valve? 2005' 222 Fisherman Thank you

Edit:

I'm sorry but it seemed inappropriate to open a topic just to ask this question... besides we're talking about tanks! However, if it's not relevant I can delete it!

Muffin - you should start your own thread on this. You don't want to be labelled a "hi-jacker" :)

Also... most of us won't click on an unknown link from a realtively new member. Better safe than sorry, you know?
 
That is were it would be but you can't tell by looking at it whether its antisiphon or just a hose barb.
If you remove it and you can't see thru it, it is an antisiphon hose barb

Muffin, yes, as indicated, it's inappropriate to post into someone else's post to ask your own question - it's seen as rude. That is why you should start your own thread.

Your pic actually shows up now, instead of link. As Skunk mentioned, you have to pull it out to check it.

Let's save further discussions for your own thread, though?

A 1998 hull will have an 82 gallon plastic tank. My hull is a 1995 model HIN that was molded in 1998 after the original hull delaminated and was replaced under warranty. It came back with a plastic tank, bronze thru-hulls, and a bow pulpit, that were upgrades over the original hull's aluminum tank, plastic thru-hulls, and no pulpit. Grady did it right!

Hulls with aluminum tanks will have a deck hatch over the top of it that can be unbolted and removed to gain access to the tank. Hulls with plastic tanks will have 1-piece decks with only an inspection port.

Hey guys, sorry for the absence, I had a lot going on and this boat slipped my mind. I was just wondering about others with a similiar boat and their experiences. I have had 208s before and it is a good size boat for me on the lake and going to the coast. it's still for sale and I plan to inspect it further. The repower 200 4s is a plus.

My opinion, and it might be an unpopular one, but the boat you're looking at is $25k? Why not spend a couple thousand dollars more and buy one that is both 10 years newer as well as one that also comes with a hardtop? I personally would rather have a newer boat with a hardtop and an older outboard, as opposed to an older boat without a hardtop that has a newer outboard on it. As long as the older outboard has been checked for the dry exhaust corrosion and checks out, and the boat has been inspected by a competent marine surveyor... that's the route I'd be going in.


 
Grady Crazy - I have '99 208 - same opinion as enfish - a great, very capable 20 footer that feels and rides bigger. Great fuel economy, trailer-able and easy to maintain. I take multiple offshore trips each year and the boat is stable and comfortable.

Mustang,

I agree with your thoughts but here are my reasons:
A hardtop, as much as I like them, won't fit under some of the bridges on the lake I live on.
The engine is a 2017 4 cyl 200 and I prefer a newer engine than one going on 20 years old, especially with the dry exhaust.
The engine weight is a good fit for a 208.
My boat lift has a 4000lb capacity. The 208 is 2650 lb and the engine is 516 lb.
The '98 is a local boat.

I do like the boattrader boats though

Just as an fyi, the 2,650 lbs is the dry weight of the vessel... meaning no fluids or fuel, likely no interior, dash, accessories, trim, batteries, electronics or anything else. Depending on the year, the fuel tank alone appears to be 82 gallons, of which a gallon of gas weighs 6 lbs/gallon... meaning that a full tank of fuel alone will add another 500 lbs to your above number. I'm thinking you're going to be several hundred pounds over the maximum capacity of your lift, if it's only rated to 4k lbs. Here's another thread on performance data sheets for a 208 Adventure with both an F150 and an F200, of which both are over 4,200 lbs. I also imagine those numbers are probably from a test boat that's lightly loaded with fuel or other gear, and am thinking you're probably going to be at close to 4,500 lbs or maybe even more fully loaded. Food for thought, of course.

Thread '208 adventure performance data/repower experience from 200 hp up to the maximum (230 – 250).'

Hi all! May this new year of 2022 bring health, happiness and prosperity for all! I would like to start this discussion specific to all 208 Adventure owners concerning your personal experience, questions or concerns you have specific to the 208 Adventure. I own a 2006 that is currently powered with a Yamaha F150 four stroke. I have just started researching to repower for the upcoming season. I am seriously considering a Suzuki inline 4, 200, but have not ruled out maximizing the horsepower rating for this model grady (230–250 depending on the year). Has anyone repowerd to the maximum...
