Hmmm... the 19" pitch should be almost perfect for your boat. The 23" pitch will likely give you horrible hole shot and bring down your rpms by 700-800 which means you are well below the recommended range (4400-4800) for your boat which will have your motor lugging. IF its the 19" prop then i'm wondering if its really a 19" as its possible the pitch has been altered with any repairs done to it. Try the 23 though just for comparison but i suspect it will be too high. As for the 'forgiving' part, the hub in a SS prop is designed just like a hub in an aluminum prop. Both should let go on impact to reduce any possibility of damage to a gear gase. Repairing a SS prop just costs more money.

a buddy of mine has a 21 pitch prop im gonna try this weekend b/f i go up to the 23 stainless prop. we'll see what happens. also going to try to GPS my speed just to make sure my speedometer is properly working. fixed it last year but could be off again

What carb? I am having a similar issue with mine and I may have a fix.

4 barrel. i believe its a holley

Re: i think i know whats wrong BUT....is it the carborator?
 

Holleys are fairly easy to rebuild just make sure to get the right kit if you go that route.

I checked the issue or idea I had to what you have and its not the same. How is the hull ? how clean is it? I was getting 3700 wot rpm and 27 mph when I first got my boat and it would not do a tick more. There was so much scum and crap on the bottom that would not let me slide.

I now can run 4500 with a 19 at 36-37 on the gps but that is it. I have completely went through ignition system minus the ignition module and have rebuilt my carb and I am having the same issue still. Can you free rev the motor past 4500? My motor will not it starts to pop and sound loaded up.

I would think it would load up a tad or smell rich but it sputters and pops past 4200 so I think I am overfueling at wot and am planning to go down a half a jet size to see if it helps me.

i have not tried to free rev the engine past 4500 rpms. that is something i will try. As far as scum on the hull.....Eric doesnt allow that too happen! in fact just the opposite i spent 3 days before we took her out the first time wet sanding and de oxing the chalk away buffing and polishing. i need to rebuild my carb regardless if this is my problem b/c i never had it rebuilt in the 3 years i owned it. i will try a few things this weekend and see what happens. im curious. will let everyone know what happens.
