First Ride in a 24' Superboat
 

Well it's been a long time coming... I went for my first ride.
The boat performed flawlessly. A big thumbs up for my Volvo Penta powered Superboat.
She is even a little faster than I had expected.
We had 3 guys, 3/4 tank of gas, full cooler of beer, and dead calm seas on the CT river.
We saw 68mph at 4400+rpm heading up river and 69mph at 4450rpm down river with a 25pitch Mirage plus propeller.
I guess if I want to see 70, I have to through someone over or install the Stainless Marine exhaust system I acquired last week.
Next ride I will try my 26pitch Bravo I prop. I would expect a 1 or 2mph drop, but better overall performance.
Anybody else get theirs in?
The warm weather is hear, Happy boating to ALL!!!

Hey Patrick,

I'm glad you enjoyed your first ride. I went out for a very brief ride today. The sun was shining when I left my house and by the time I got the boat in the water it started raining. The rain drops felt like needles at 70+. How many RPMS are you wanting to turn with that engine? Are those GPS speeds? With 3 guys, full gas and beer I'm at about 70 gps.

Dave M.

Glad to hear it ran good for you Pat!! Do you still need a set of heads?

Talk to you later,

Hi Dave,
No, The speed were not gps. My batteries were dead. Don't burst my bubble. Next run I'll compare.
The 7.4MPI tops out at 4600rpm stock, I think the rev. limit is set for 4650rpm. If I get close to 4600rpm with the high performance exhaust and a light load, I have a back up plan.
I purchased from a racer in Fla. a nearly complete Merc. 7.4MPI system including a reprogrammed brain. The brain was re-calibrated by Arizona Speed and Marine. The rev. limit has been changed to 4950rpm and the fuel injector mapping adjusted slightly as well. I spoke to them about the changes and they told me it would work on my stock or a slightly modified engine. Just plug it in.

Congratulations,good luck,sounds like a good ride,i wish i was that far on my boat,here we are,another rainy day,but im close,im planning to do the NYC poker run,its a good one,then Superfest :D :D :D Tripps

Congrats Pat sounds like a good start.The 26 bravo is the only way to go, The mid range will be incredable and handle rough water better.My 24 baja was uncontrolable with a mirage,Just think lab bravo.The Zuperboat is still covered, I promissed my wife I would finish the deck first. Hey Tripps did your gauges come in yet. Also im still looking for a set of flags for the bow of the boat anyone have any ideas

Hey Zuperboat,
The guy that did my flags will sell them for $33 if they are the same as mine. They are 12" tall. He used a new process of spaying color on to white vinyl. They are not quite as sharp as colored vinyl, but I think they look OK. I can e-mail you a close up if you like.

Hey pat that would be great. A buddie of mine said the vinyl is white and the computer puts the color on it so I could get it waving with shadows,Like 3D. But this is the same buddie that was to have my grafix done by May first EMAIL [email protected]

Well I would saw that my second ride was even better than the first. The temp hit 70 and my boat 68. Tried to confirm the speed but my GPS didn't find enough satellites until I was back at the dock. Hope to try again tomorrow.
Ran a 26 Bravo I today and I would say the overall performance is far better than my 25 Mirage plus. 68mph on the speedo and 4400rpm on the tach. I only lost 1mph and 50rpm with the four blade. Hopefully my Stainless Marine exhaust will get me to 4600rpm, if not, I guess I will have to lab the prop.

PAT SEND THAT PROP TO MERCURY FOR A LAB FINISH FOR $350 AND GET 300 MORE RPM THEN 70 WILL BE NO PROBLEM. THE MOTOR WILL ALSO RUN BETTER AT 4700 .I THINK AT 4400 THE MOTOR IS LUGGING TO MUTCH. CAN I GET THE PHONE NUMBER FOR THE FLAG GUY AND I WILL CHARGE THEM.
