Only idled out for like 10 minutes and the starboard engine misfired and stalled. Could not restart it. Went home on the other engine. At home started both engines again - seemed fine. Let them idle for ~ 10 minutes. Oil pressures and temperatures fine. Headed out again, only got a couple hundred meters and there was a bad knocking sound in the starboard engine. Shut it down and went home on the port engine. So ........... not sure what the forward plan of attack should be from here. Frustrating really. |

In the meantime, what props do you have and what is your RPM at 82mph? My boat with 540s was setup with 29p Maximus and I only achieve 4950rpm. I don't have enough motor to turn them. I see 80 easily, 82 is my best. I just bought some different props and as soon as our water is liquid again I'm going to test and I'll pass that info to you to see if I get more RPM and speed. I'm betting you have the same props I do. |

It still amazes me how quickly I got comfortable going 80+ after owning a 21'r that only went 50. I'd feel safe in my 382 at a 100+. It's the most solid go fast boat I've ever been in. Now that premium is less then 2.50 we go fast a lot more often.

I saw a 382 with vortech blower and Arnesons on one of the FB groups last week. Guy said he hit 102 and felt he had more.
|
Bumping this up. I saw on Facebook another 353 running 106. Pretty cool.
My boat keeps getting faster and fasterwith age....still slow but I hit 87.1 this week with stock 540s. Maybe this winter some more power. |

I think he said right at 800

..:: I SAY ITS TIME FOR ME TO MAKE AN OFFICIAL "LIST"::..
Of the fastest Formulas. SPEED, HULL SIZE, ENGINE(S), DRIVES, PROPS, OWNER All have to be verified, none of this "well my buddies is pretty fast, so I think its about 100mph cause it really blows my hair back" |
All of the fastest 382 formulas I've seen have Arneson's....

“Lake effect” cleveland Ohio, my best friend 107 was best, 509’s pro charged with box stock Gm perfomance edelbrock heads, 7lb boost
boat is fast.. https://cimg2.ibsrv.net/gimg/www.off...392691778.jpeg https://cimg3.ibsrv.net/gimg/www.off...1655553b8.jpeg https://cimg4.ibsrv.net/gimg/www.off...db097819b.jpeg |
Years ago I bought a 382 with 8PSI Procharged 500efis/XR drives......ran a best of 98 mph.

So far, takes a lot of gas to get there with near perfect conditions. From 3 years ago and only attempt at top speed. Arneson and 750x2 |

My Arneson drives have been a solid performer. Bravo XR's were a big problem, even with original power. You'll gain top end speed. No docking issues, just different. With my install, we did have to move the motors 3" forward. I used a local shop and they worked with Rik on the install.

Nice set up. I was Real close to pulling the trigger on Arnesons after I ate several sets of XRs. Talked to Rik a few times.
Decided on SCXs mostly because of the cut yo AzZ in the water when swimming if not really careful. Not that Drunks are not careful. :lolhit: and don't forget the Rooooosttt!! Close to 800HP on my punched out 575's. |

They look great. Is this a 382? Did you pickup any speed over the Bravos? |
382 Pokerrun with a Kevlar hull. Picked up around 4mph over XR’s
