1976 70 hp evinrude running issues

[loggyb123]

I have a 1976 70 hp evinrude that starts and runs good. When out of the water I can shift into forward and reverse and Rev it up in both directions. When I put it into the water and shift either forward or reverse I can only get a little bit of throttle before the engine bogs down and dies. Like I said in neutral I can Rev the engine all the way up just fine. It is only when jt is in gear and in the water does the engine die when I try to throttle up. Any help would be greatly appreciated.

Thank you

Sounds like a carb motor, with dirty/ blocked fuel p***ages?
Also, revving it above 3k RPMs in neutral, is a good way to destroy that motor.

Good luck.
