Here' my 10 cents on the boat ride/attitude.....................calm waters need to be back in the 28-32% cog range..............a little further up for rougher water.

Here's an example of my very similar boat........32" Pursuit in calm water..........i like this kinda ride, up top on the pad. Higher 40's on 4s and hit 59 on 5s for a quick test run.

ran on 5s today, hit 40 mph, first time driving a fast boat and it was great!

never had good experience with the stock electronics although the same gear kicks a$$ in my sv27 with a 42x55 prop. Go figure.
changed the motor to a leopard 4074 2200kv and esc to seaking 180. running with m447 prop on 4s1p 5000 40c batteries. temps are all below 100. remind you the temps here are pretty cool now.

What do you think you are getting for speed with the M447?

I didnt have a GPS but my guess would be high 40s to low 50s. I have a GPS now however everything is packed away for winter
Here is a little video, water was a bit rough so I couldnt get the full speed for long

Time to take this thing out of winter storage.

try an x442. its 42mmX58mm pitch, little more than your 42/55 grim.
