Fuel starvation prblms

[seafever3]

I have twin Mercruiser 60hp ELP Bigfoot engines on my houseboat.<br />When running upriver at aprox 3200-3400 rpm one engine<br />loses rpm down to about 2200 for about 1 min and then back<br />up to 3200 rpm for about a min then back down and so forth.<br />I have changed the fuel bulb several times and that does not seem<br />to help matters. This seems to happen only when the engine is<br />under a load. Going with the river current does not seem to<br />affect the engine. The other engine has no problems.<br />Thanks,<br />Dennis

Before spending time and money.....swap fuel lines and spark plugs to see if the problem follows.....

Compare peehole flow of other engine.......check fuel filter on engine too..seperate tanks?<br /> Are they open vented?

You might take a look at the anti siphon valve on that side also.<br /><br />Good luck!
