Default 2001 evinrude 70h.p. 4-stroke

Motor runs good till about half throddle than suddenly falls on its face. Checked fuel filters and they seem to be clean. Motor doesn't die it just boggs down. Never fails to start , idles smooth, no miss, seems like its running out of gas. Can anyone tell me what might be the problem. Thanks!

Check fuel supply for restrictions or air leaks in hoses or connectors, restricted vent on tank.

Get a Service Manual ('01 Suzuki DF70) and check out the vapor seperator and the high pressure pump.

Good luck.

What JB said. when mine was acting up past 3/4 throttle I found out I had quite a bit of water in the vapor seperator/ high pressure pump housing. There is a little drain screw to empty out. Also change the plugs, mine seems to like a fresh set of plugs even when they still look good.
