Well got it in the lake. Unsure if its a pump issue or a carb issue. It'll run decent then act like it cant get fuel. If I keep pressure on the primer it'll stay running. Though if I let it run out and stall. I can pull yhe line off the fuel pump and pull it over and its pumping fuel when I pull it over. That sound more like a pump? Or more like potentially a float issue?

You may have a Blockage in, or an internal collapse of the Fuel Line between the Pump and Carb. How old are the Lines?

 

[Bman2895]

Brand new fuel line. Brand new primer bulb.

Now my line is like 6-8feet long would that matter? And Ive heard the primer needs to be in a vertical position not laying horizontal. Is that true?

And i found a couple of issues when I got it home.

1. The fresh fuel is no good. Not sure if it was in the tank and I didn't notice or i just got it from the pump but I've got water in my fuel. Not a ton. But it only takes alitte to grief an engine.

2. The carb is definitely needing help. The bowl gasket especially has turned to almost goo and made a mess in the bowl. The float and needle is missing the little keeper that holds the needle to the float. Both the main and idle jets adjustments feel pretty sloped out. I think due to the seals being crappy. Ive got a kit coming.

3. Im suspicious of the fuel pump. It seemed to be pumping okay at the lake. But It wont barely pump when pulling it over at home. I read they won't normally pump at hand cranking speed and only really pump when running? If that's the case then that's pretty much how it behaves. But I ordered one anyway. The longer style not the square.

I was referring to the Line(hose) between the Pump and the Carb. Can look fine on the outside, but be a mess on the inside. I know you added a Fuel Pump, but if the Hose is original, it is 70 yrs old and likely in poor condition. Alcohol in the Gas certainly doesn't help

source of your parts ?----Amazon parts from the ----hooflungdung----Empire?

If the motor is in good shape, then it is worth fixing everything, hoses, fuel pump, carb rebuild etc. Once everything is fixed it will run for years !

Yeah that line checked out good.

Yes and no. I did order a kit and pump through Amazon. However. I also ordered a Sierra kit for the carb. The Sierra kit is supposed to be here in the morning through O'Reilly's believe it or not.

I can't find a OEM or similar pump. Just rebuild kits.

Seems to be. It definitely has to work to push this boat. But I figured it would.

That motor should make the boat fly.-----Listen to folks and find the issues with it.

The boats a 14ft crosby sea sled that's had a hard life. I had the boat for a bit and sold it. It resurfaced on marketplace and i got it back cheap. But it now has roll on bed liner on the hull. The rubbery kind. So im sure thats hurting things. Boats rated at 40hp and before the hull got coated the 25hp i had on it did pretty well.

 

[racerone]

Sorry, my mistake.--Thought it was on a smaller boat.
