Volvo Penta 4.3 GL Fuel Starvation Intermittent

[wilke1]

I have a 98 4 Winns Horizon with a 4.3 GL.
Engine starts and runs fine. After restart, the engine will get up on plane but will stall out as if out of gas. (If I wait long enough, the engine will restart and be fine). Inspected accelerator pump and no fuel going into venturis. Power to the pump is observed during cranking.

I can jumper the pump and I can hear the pump load. I pump the throttle and observe the accelerator pump is working, visual of fuel sprayed into carb. When issue occurs, I can jumper the pump, it runs but I do not hear the pump load and no fuel from the accelerator pump.

I suspect the fuel filter.

I removed the filter/water separator and drained it into a clean container, There was no water evident but some minor contamination. I cut the filter open. The paper was not clogged but did notice a film of some sort. Maybe the water separator film??? I bought the boat used so I am not sure when it was last changed nor if fuel additive was used over the winter.
I pulled the pump off and inspected the wire screen. It looks clear of any contaminants.

I will chagne the filter and try again.
Could this be a fuel pump? I hate to spend the $200. for a pump needlessly.

Thanks in advance.

Replaced fuel filter. Ran with muffs on Friday for 2 hours no issue. Took out Saturday and ran all day. No issues.


Thanks to this site for previos posts.

I am having the exact same problem with my 96 Four Winns 180RX
I have the Volvo Penta 4.3GL with a Holly 2BBL Carb.
Off the trailor it starts right up and runs great for hours with no problems at all.Then we shut down and float for a couple hours an restart with no problem until we take off an as soon as we get planed ithe carb bowl is drained out of fuel.
I replaced the electric fuel pump,Fuel/Water Seperator spin on filter,3/8" fuel line all of it and the anti Syfone vale at the tank.
End result I still have the same problem as I started with.

Now if I start the boat and let it idle for 3 to 5 minutes before I take off everything is fine but I have never had to wait before taking off in the last 11years of owning the boat so I am missing something somewhere.

Start a new thread with your question, don't just post at the end of someone elses question. after a couple of replies no one will even see your post, plus one never knows who's question is being answered.

I already started one 8 months ago and it ran out of solutions.
I was just glad to see Im not the only one with fuel issues on these 4.3L

Then bring your old thread back up. At least then we would know what was tried and what wasn't. From here you are just starting over.
