Help please i have checked high pressure fuel circuit with gauge after removing bigh pressure fuel bowl and changing all fuel filters i have also taken the boat for a run with a auxillaru 20 lt tank hooked up with no difference. My mind is pointing towards the low pressure fuel pump or do i need to get it put on the computer. No fu/kwits please

To the point !! Mate I'd be taking it to a dealer service agent. You don't mention 2 or 4 stroke or age/number of hours....

Check the Flux Capacitor.

Can't you just jump on eBay and buy some more rpm's?
It even comes express post in a box..

Check the Flux Capacitor.

Sort of asked for that. :lolk:

Could be anything from throttle likages to a plug breaking down under load to a blocked injector. Start with the cheap stuff first. Get a workshop manual or as suggested, see your dealer.

Don't you guy's know anything - only E-TEC's have a flux capacitor.

I guess that's why they bag four strokes all the time.

See - it's even got its own section on testing it in the service manual. Can't find anything on Ebay RPM's or Powerbands though - must be 4 stroke stuff

Get a fuel pressure gauge on it at the WOT, this will tell you where you need to L@@K (L@@K)
