New to forum, 1991 Gamefisher 15hp

[CDM88]

Hi all. Recently acquired my first boat, 14ft jon boat with 91 gamefisher 15 hp outboard. I was able to get it running and just replaced a badly damaged water pump impeller. After putting the lower back on, i noticed a black plastic block on the shift linkage that prevents the throttle from advancing past “start” when neutral or reverse is engaged. I can only twist the theottle all the way when in fwd gear. Is this normal or did i throw something out of whack when removing/reinstalling the lower end?

I re posted on the “other brand” section as it seems all the gamefisher questions are posted there. Not sure how to delete a thread yet.

Normal.
That keeps you from over revving and throwing the motor into gear.
You have the model, serial#
The old impeller, did it come out in one piece?

The Force 15hp didn't use a thermostat until late 91-92.
The old impeller if it broke up could be stuck in the thermostat.
You might have a problem? Maybe not? Model and serial# ?
