I have a predator 22 hp motor on an old go devil frame. anyway its new to me but I tested it out on the water today with new fuel line brand new gas in it. I got it up to about 16- 18 mph and then it started to bog down after some driving around and conked out. I was able to get it started up but it wouldn't push the boat it kept bogging out at top end. it did fine idling around but, and out of the water it revs up with no problem. this boat has been a huge under taking and I am about to just sell it and start over.

I have a backwater with the predator 670 on it. I just took it out a couple of weeks ago and it was also bogging down at more than half throttle. Last weekend I installed an in-line 12v fuel pump. I’m going to test it out this Saturday. I’ll let you know if it fixed the problem.

This.

You need a low psi fuel pump to keep up.. been there, done that.
