1987 Power Play XLT-185 - floors, stringers, and upholstery

The regulator will cure the overpressure.

There have been a few high pressure issues recently with mechanical pumps.

Did you install the spacer on the pump?

As far as I know it's the original pump from 1987. I bought a new one at the parts store today, but after getting home and comparing, I'm guessing I need a marine-specific pump. The one I got doesn't have a flared line inlet and doesn't have the vent line nipple. I went ahead and picked up a regulator though and got started on installing that. Nobody around me had 3/8" hard line to make a new fuel line with, so I had to order some. Should be here Tuesday.

Summit Racing has Carter marine pumps for under $50

And yes you need a marine pump

Made a bracket to better manage my remote oil filter hoses. It bolts to the back of the manifold and will keep the hoses from rubbing against each other and against the edge of the bilge.

I've got the bracket for the fuel pressure regulator made and the pump-to-regulator hard line bent and flared. Should be able to knock out the regulator-to-carb hard line tomorrow.

 

[todhunter]

Regulator installed, fuel pressure set to about 3.5 psi in the driveway. Going out tomorrow with it to see how it does, with some friends ready to tow if it floods out again. I threw away probably 4 iterations of the hard lines before I got ones I was happy with. Good thing I bought 25 ft of hard line!

It looks great, thats half the battle

 

[todhunter]

Boat did good today, so I'm cautiously optomistic!

 

[todhunter]

I had 3 successful days in a row this past weekend with the boat on the water, and it never flooded out. It did act "cold natured" on a couple of starts, but I'll take that any day over the issues I've been having this season so far. It feels good to be back to just enjoying the thing.

 

[todhunter]

Boat is still running great, but today one half of my whale tail pulled off and took some of the cavitation plate with it. I'm just going to ditch the other half of the whale tail and enjoy the boat the rest of the season, then this winter when I pull the drive I'll weld in some aluminum plate and repaint it.

 

[zool]

Hard to think water pressure did that, maybe u struck a log or something?

 

[todhunter]

I mean it's possible. We were watching pretty close for wood, but I know you're never gonna see all of it. Whatever it was, I'm thankful that was the only damage.

 

[Scott Danforth]

My guess is micro cracks started over the years. Once they started it's only a few more cycles until failure. You should see larger and larger beach marks radiating outward from the mounting holes

 

[todhunter]

I winterized the boat last weekend. We wanted to do a fall leaf tour of the gorge, but my truck's transmission died 2 weeks ago, so no more boat hauling till that's fixed. Since the drive is off, I went ahead and started fixing the places where the whale tail broke off.

This is what I started with:



Sanded back the paint and cut some plate to fit the first missing chunk.


Welded top and bottom:



Blending the repair:



Finished with the first one:



Welding the 2nd missing chunk and holes where the whale tail was bolted on:




I still need to trim the 2nd plate and blend everything in, then it'll be ready for paint.

Looking good

What wire are you using?

 

[todhunter]

What wire are you using?

ER4043

Here's why I asked:
I remember using some 5356 on soft extrusion once because we ran out of 4043. The welds were pretty, with pre-heat and good penetration. However, a couple of days later, those parts literally fell apart at the fusion line. Material mis-match caused some sort of crystallization I suppose.

So, I avoided using that wire until someone brought me a casting from a traffic signal base. The 4043 wouldn't even bond. But (you guessed it) the 5356 worked like a charm!.

So when I see a casting of unknown material, I have to wonder if it is in the 4043 range, or in the 5XXXX - 6XXXX range. Based on my limited knowledge, I will always default to 4043 to start with, rather than the other way around.
It certainly work on your repair, and looks great, by the way.

Good info to have! I don't even have any 5356 filler, so it's safe to say I 100% rolled the dice! Hope it holds...if not, grind, rinse, and repeat.

Interesting about the 5356 on that casting. I've always used 4043 myself on castings and have only had a weakness in the heat affected zone

To be clear, I normally used 4043 on the extrusions that I was fabricating with, but I ran out and substituted 5356, which led to the delayed failure.
That's where the failure occurred; in the heat affected zone. Where the weld stopped and the parent metal remained. It was a clean separation.
It held initially.

As for not being able to use 4043 on the particular casting that I mentioned, it simply wouldn't fuse, as I recall. It just wadded up. My memory is a bit foggy at this point. It's been decades.
