86242, Do you have seperate cooling raw water pump for your 509 or do you just use the alpha.

Thanks

I agree with the others that you should see low to mid 70's. I have around 525-550 hp and I see 65 mph in chop with a mirage 21 non plus that is not in perfect shape.. With the prop dialed in I should be around 67-68. Great boat, it just takes a lot of power to get moving fast.

Hey I run out there to. What colors are your boat? I have a 233 with a 632ci in it . with a bravo The best I can get is 77 gps. I did the transom change over from alpha to bravo after I wiped out two alphas. The boat was scary I did a full hydraulic setup with a box on it now. Its much better

What rpms are you turning with that 23 pitch prop. IMO it takes a lot more power than mid 500 to get to 75 in a 242. I have between 525-550 hp and I'm only getting 65 mph via gps?
