Anyone replaced the floor on a Javelin 379 or 389???

[Javelin397T]

The floor immediately in front of the gas tank on my '93 379T is soft. :facepalm:
It's the area just in front of and underneath the glass shell that the seats bolt to. I pulled the carpet and it looks like the glass has separated from the wood and lifted. It pretty much spans the width of the seat area and only comes as far forward as the drain. I imagine if I break through the glass I'll find rotting wood as the boat had been sat outside for a few years without a cover. Just wanted to know if anyone here has had to replace this section of floor and managed to do it without taking the cap off? The floor from the drain forwards and under the console feels and sounds solid. I'm assuming that where the boat was sat out in the rain, the carpet soaked up water and then allowed it to pond around the drain and screw holes at the base of the gas tank cover; where it slowly seeped into the floor and caused it to delaminate.

I haven't done any core samples or cut into anything yet. I've pushed on the motor a bit and it seemed solid. So I'm thinking of just finishing up the re-wire I've been working on and run it a few times; then I'll make a decision next year as to whether or not I want to tear into the floor and anything else I find below it.

Your decking is probably just the top of the iceberg, I suspect you'll have a mess below deck waiting for you when you start tearing out... it's pretty typical for what you describe.

As Jig suggests, a 'small' soft spot often hides more problems below decks, even the pressing up & down on the motor (in the tilted fully up position) and tapping on the fiberglass transom tests can give false confidence.

I don't remember the thread, but you don't want to unexpectedly discover that there's a problem:

Unless you need info specific to Javelin, the large majority of boats are built similarly w/ similar materials......

Replacing the deck & stringers can be done w/out removing the cap, but it is nearly impossible to replace an OB transom w/out removing the cap or some portion of it.

There's a Javelin owners group: Javelin Boats

That pic looks good J!

It's what I visualize every time someone says their deck has one or 2 soft spots and they're going to run it for this season and fix it during the winter.

Thanks for the advice and the link. I'll keep on reading for now and study up!

Here's a thread about a boat that just had a small soft spot in the deck:

That was another iboater's misfortune, I am (as is the owner, I'm sure) glad that it occurred backing down the sanded beach ramp, instead of after launch :facepalm:

He hadn't had it very long & had done the knock on the transom & jump on the A/V plate, it passed. His Admiral was not happy to have the transom torn out of their boat after paying too much for it in useable condition, let alone after this pix was taken, and to be standing next to it in public as he tore it apart

There's another around here somewhere of a bass boat, that was almost a catastrophic failure while under power crossing a wake. It was pre my acct w/ photobucket & I didn't save the pix...

I just bought a 1995 Javelin bass boat. Model 367A. No floor issues at all. It has a 1995 115hp Evinrude Intuder engine with a 13 1/2 x 22 Raker SS prop. Hole shot was terrible. I put a SE300 Sport hydrofoil on it and it pops out of the water in seconds now. Top speed is 55mph gps with one person and 22 gallons of gas, 3 batteries, built in 3 bank battery charger. 53mph with 2 people (420lbs) and fishing gear. Rpm?s wot is 5700. I didn?t loose any speed with the hydrofoil but maybe gained 2mph. Nice boat in great condition for year model. 2 color fish finder with di in front + gps. 70lbs thrust Minn Kota. 3 new tires and canvas boat cover. I paid $2700. For it and really like it. It has had new carpet installed before I bought it but the floor is solid. I checked the hull and the transom for rotted wood. It was solid. Engine had a new lower unit installed last year. No water lines on the hull. Keel guard was put on when new. I am the third owner.

What does this have to do with fixing a Javelin? And the thread is old and inactive!
