Uh-oh....Repowered 2320 is "Underwater"

[no limit]

What did I do wrong?

I bought a 2320 and based on comments, decided to repower with a 250 Etec and thought it would be no problem as they are lighter than other 250's.

http://www.akmining.com/boat/evinrude_outboard_11.htm

With a full tank of fuel (150 gallons), the scuppers are 1/4" above the water line. The boat has two batteries in the rear port compartment and the oil reservoir and pump in the rear starboard compartment.

However, add a cooler and 4 adults and at times, the scuppers go well below waterline and will actually flood the deck with an inch or so of water.

It runs great - 45 mph WOT loaded as above but that flooded deck is a deal breaker.

Any suggestions? Maybe a flotation type bracket?

I sure don't get it ... any other 2-stroke V6 would have been a shade under 500-pounds and that new (assuming 25" leg) E-Tec is only 524-pounds.

Short-Term I'd add ball-type scuppers from Rabud or T-H Marine, where I prefer those by T-H as you can loosen a set-screw and turn the housing off 1/4-turn to clean debris out of it.

Tell us more ... did you add anyhting else? What was the old OB? Did you upgrade your batteires? by itself this conversion makes NO sense.

FWIW I went from a 486-pound 2-stroke V6 225hp to a 586-pound 250hp V6 Suzi 4-stroke and my transom on my old mod-V 2520 didn't budge ... though I did remove the old oil tank of maybe 20-pounds filled total ...

Oh, I have half a barrel of Bomb XD100 full-synthetic oil for sale @ $25/gallon if interested ...

I recently repowered my 1995 2320 with a honda 225 .I have a notched transom and the only time water is a problem is with a full tank and I back out of the ramp to fast.I think my Honda is a tad heavier.

Dale,

No mods to the boat and the original was a 2 stroke Yamaha that was 100 lbs lighter.

All I have mounted in the transom are two batteries and the oil reservoir. I also called Parker prior to repowering and they said that it would be no problem. The bilge is dry and I never saw it in the water prior to purchasing. Your 25 has a broader beam and maybe that is why? I just dont know.

Hammered,

I have that problem too. Water gets thru the small gaps on the hinged transom door. I guess I can put some foam to seal those cracks and keep.

I am looking into the positive buoyancy brackets and will report back.

The only thing I can add is 2320s 2005 and earlier are significantly heavier in the ass end compared to 2006 and newer due to the gas tank being further aft. That's why V6 four strokes are no problem on the newer hulls. A full tank in the older hulls only makes the situation more apparent.

Things you can due to to counter the increased weight of the further aft gas tank are heavier ground tackle/chain/anchor forward. Put your cooler amidship. Try not to store or place heavy gear in the transom area. Performance items for underway handling/stern lift and attitude control.........12x18 tabs and a permatrim. YMMV

My 2007 2320 factory rigged with an F250 has the same issue with 1/2 tank of fuel, 4 adults and cooler in the rear. I love the boat but will admit the water flooding the deck irks me. It also lists (leans) slightly to starboard when tied up in the slip, i figure its due to the 2nd steering station and all the rigging, wires, etc. that run along the starboard side.

Wow......that's really strange. I am sitting here with 120+ gals of fuel, gear for an overnight, 160# of ice, a 325# knucklehead on the stbd transom and 230# knucklehead on the port transom, full livewell, probably 60# of fish on the deck and I have no water on the deck issue whatsoever. I dunno, I must have got lucky or something with this hull. There is no way I would tolerate fishing on a deck with water on it. :shock:

FWIW she sits level, but no second station.

 

[Lights Out]

Yeah, im not sure what to say, im looking into the different ball type scuppers in an attempt to fix the issue.

Why did Parker ever mount the fuel tank so far back.even when mine had a two stoke she was stern heavy.If my fuel tank ever goes bad I just may move it slightly forward.

It is a known issue that got redesigned in 2006. I would love to see a 2320 gas tank partitioned into two chambers.......100 gals forward and 50 gals aft. It would definitely give the owner more options with regard to weight and balance issues. I would run the aft tank empty most of the time.

FWIW I have a 22# Delta anchor, 35ft chain, Lewmar Windlass and 400 ft of 1/2 inch line up on the pulpit/anchor locker. All my heavy tools/safety gear are carried in the two port/stdb compartments under the V-berth cushions. My snapper/grouper box is carried amidship forward of the livewell. I also carry a standard shaped 150 qt cooler in the cabin on the deck in the V-berth for longer fish and extra ice storage. The boat sits level in the water with this config........I am happy with the way she handles.

I also have a Lewmar windlass, 14lb anchor, 35' of chain and 350' rode in the locker..... I don't really keep anything in the transom but, I do prefer the cooler situated in the center at the rear.... I also have a 25 gallon live well situated on the swim deck but, regardless of whether or not it is full water still comes in, its just worse when using the live well but, not that much worse really because the boat naturally leans to starboard side and the live well on the port side sort of balances that out.

Fuel tank location is not the only problem, 600 lbs of motor sitting on a arm 30" behind the transom makes the 2320 stern heavy. The stock bracket provides ~250 lbs of floatation. Adding flotation makes a huge difference, adding two tanks to the bracket added 500 lbs of flotation.

My 2000 hull sits fine in the water 225 2 stroke. I can fish 5 guys full 30 gallon live well plus cooler full of refreshments :wink: and I have never taken water in on the deck.

pics below show how it sits at the dock
and the other pic is anchored up fishing with 5 guys on deck all over 230 pounds

Who made the extra flotation tanks?

I made them, fiberglass over foam.

Great job!! Looks better than factory

VERY impressive sir!

Pretty awesome.....anyone else out there do anything like this for flotation?

I have an update - I bought weather resistant gasket from mcmaster carr and put 1/2" thick sticky back foam under the hinged transom door. I tried 1/8" thick going up on the sides of the door but that was too thick.

In any case, it stopped the deck from getting flooded while drifting when a wave or wake over the transom notch. Some water did get in thru the sides of the door but it would typically drain out thru the same crack.

Sealing that 3/8" gap UNDER the door really fixed 90% of the problem and will get a thin gasketing material to take care of the sides. Again, the problem is wakes or waves gushing over the notch while drifting.

BTW, I see that 2320 with brackets dont seem to have any problem so I guess the deck is above the water and the full transom keeps eliminates the swamping problem.

Can you share more details on your setup? What year? Is that the original "Stainless Marine" bracket that you then added some pods to? Were they custom-fabbed, or something you found?

I too have this problem and it is the ONLY thing I don't like about the boat. Its an older model, so it was always ass-heavy, but with a full tank (150 gal) and two guys standing in the back at the slip, it ships several inches of water past the ping-pong ball scuppers. I have two optima batteries in the transom and a new Honda BF225 hanging off the bracket. I've added a permatrim, and when up on plane she runs great, but anything under plane, she throws a huge spray off the motor and if I stop suddenly, water will wash over the motor.
