Pontoon Fiasco

[500bbc]

My buddy has his 'Toon at Katherines Landing.
Had new pontoons installed aluminum instead of the steel originals.
Boat sits 18" higher becuase of the weight change, prop barely touches the water.
Who's got the simple solution if there is one?

 

[BingerFang]

A bigger prop?

 

[DarkHorseRacing]

Fatter friends?

Sandbags. Or they can take on some ballast.

 

[Albert]

4 sand bags in each corner

 

[DRYHEAT]

Couldn’t they just lower the engine mounting point assuming it’s an outboard or two? Or maybe convert it to a V-drive

 

[Fun Times]

What engine model? Year?

Longer driveshaft if lowering the engine doesn't get it down in there properly should it be an outboard.

The redneck solution is quite simple, just put water in the pontoons, till you get the height you want…

 

[JFMFG]

I’d suggest the MERC600 Outboard.

 

[Javajoe]

So the company that switched them out had no idea of the outcome??? Amazing
18” is a lot

Pics or it didn't happen.

I'll work on it, he's lit right now.
He told them to account for the weight difference, they knew better.

Or until you accelerate or decelerate.

How big of a pontoon is this, sucker must be huge

So....

Just the tubes were replaced, and everything else is the same??

What was the reason for this??

Outdrive, I told him to make it a jet.

 

[shintoooo]

Poke a hole in the toons?

 

[500bbc]

Yes,

Not sure, it's a 1997, deteriorated toons? He told them to raise the mounting location.

 

[rivermobster]

Mine is 28ft.

You can clearly see that the engine is attached to the tube.

If they replaced the tube, why wouldn't the engine be in the correct location???

Is this a delayed April fools joke or something?

 

[shintoooo]

Maybe they filled the toons with helium?

 

[500bbc]

Or gummies...

Everything the same , AL much lighter.

50', outdrive, think houseboat

If the drive is IN the tube, as most are, still doesn't make any sense.

Need pics.

Step was below dock before

Not familiar with toon rigging. I'll see if he has a pic of the drive.

Or gummies...

Maybe the person doing the weight calculations was on gummies.

Those look like they are titanium toons. Much lighter and more durable so they are more water resistant and that’s why they sit higher on the water. Tell him he needs a heavier motor on the back to offset that. Like maybe twin 500’s.

 

[Dog]

Shafts to short... try some gummies or generic Viagra.

 

[riverroyal]

Water is 8lb per gallon. Do some math. Fill the logs.

 

[wzuber]

Typically there is only a center pod on those to house the eng./drive pkg on outdrive type installations, not a full hull.
What a fun situation. The owner really had no idea there'd be a weight difference? The shop doing the swap either? I'd be real concerned about the quality of the shops work if that's truly the case....

Inertia...think crusing along then lift, or turn or accelerate

 

[riverroyal]

Yeah. I know there's that.
Could be a fucking washing machine in the logs.

I'd sell as is

 

[wzuber]

They could just Fab up an extension for the pod assembly and lower it too. It's just more $$$. Could probably use the extra space for something too?

 

[rivermobster]

As you can see in the pic you posted...

The logs are welded together, every four feet or so.

You COULD actually fill the center section completely, in each log, and not have to deal with that issue.

Then sell it ASAP!

 

[wzuber]

We heard you the first time.

 

[HNL2LHC]

Or gummies...

No way it was RDP gummies, If it was it would be high AF.

As for the fix attach a universal weigh bar. You can increase the weight as needed or remove is you have samoa up front.

 

[Rayson1971]

Swap out to twin outboards and mount them on the sponsons at desired height.

 

[attitude]

Maybe they filled the toons with helium?

Well at least he’ll get better fuel mileage

^ Oh dang, this is a real boat with a serious how to fix type question...Have you considered asking your question on a boating forum website?

Owner did, he told the shop before install.

 

[monkeyswrench]

Were the previous toons of the same design? The displacement would make a big difference, and that could change by the bottom.
Also, steel isn't just heavier, steel with a bunch of water

Crap, those new logs had to be big money too!

 

[Cooter01]

Another option is to beat in the bottom of the toons so they are not as round and big, beats filling them up with water.

Original pontoons are steel ??
Was this purchased from navy salvage ?

 

[oldman]

Seems like a huge awe shit, someone should have had some specs. on weight difference and buoyancy.

Adding weight seems like less than an ideal option, but if it's low and equally spread to match the original weight maybe its the right choice.

Sitting higher and having the new toons lighter than the old ones does this create a lack of ballast issue? causing this thing to be top heavy and unstable? It might be a stupid question but not really knowing what it looks like It's just a thought.
