ok took it out this morning.Starts good,idles and runs ok 1/4 throttle.When I try to give it full throttle it will come up to full rpms for a couple seconds and then just loses rpms and dies.

Check gas tank vent, gas lines and filters. Just a start.

I had one that had a crimp in the fuel line under the deck. Ran just like yours -- fished another line through there and I was good to go. I could actually watch it suck all of the fuel out and collapse the pump bulb as I was trying to throttle up.

I don't know how far you are from Liverpool, but gregr1971 will set it straight for a super fair price! I ain't kiddin'. Send him a PM. We're lucky to have a guy with his skills hangin' out with us on this forum. - Sandy

Could it be the fuel pump diaphram. We had one do things like that only ours would run 5-6 minutes then shut down. Could be electrical also as in heats up and disconnects, then cools down and reconnects, etc. Lotsa stuff can go wrong and the more techno it is, harder to troubleshoot.

When was the last time you did the Carbs ?

I would do mine on the 88 spcl every 18 months ....... the jets get clogged

That's where I would start .......

Don't just rebuild them Fuzzy. Make sure You syncronize them. I rebuilt some on a 70 evinrude and it ran like crap until I had them synct. That was ten years ago and My uncle still runs it with no probs with nothing done to it but plugs and lower unit oil. Best running O/B I ever saw.

I finally put it in for a test run.I'm a happy man.Ran about 40 mph.Thats plenty fast for that sliding flatbottom.With the 70hp it did about 32 mph
