Well, I'm still having major throttle problems on my Whaler Revenge 20 1987, with a merc black max 150, and quicksilver binnacle mount control box with the trim adjustment on top of the knob.

I brought it to my local outboard guy and he's telling me everything's working mint on land. He wants to splash it this coming Thursday to see what it's like running under load. He's going to run it in the sound on Thursday.

However, when I ran it, (keep in mind I've had this same issue since I bought the Revenge last August), I'm having the following issues :

No throttle response when in forward. I'll have to push it to 3/4 just to get it to move beyond real slow.

The throttle will not stay open, it falls back on me, I have to keep it pinned with my hand and steer with my left.

It won't get up over 4200rpm at WOT, and then if I'm lucky it'll "catch" all the throttle and sponttaneously jump to 5500 rpm (where I believe it should be at WOT)

Top speed is approximately 26 mph via the Sitex and GPS.

The throttle doesn't stick, it seems to shift fine, and it's not utilizing the full power of the motor.


My local guy said I would need to switch to some Gen 2 merc controls or something at absolute worst?

But the motor screams, I know the motor runs well... What Gives?

What dou you guys think I should do?

Any response is greatly appreciated.

Graci,

-J.
