12-14'/Rotax 582 Performance Questions

Postby AlaskanOutdoorsman » Mon Mar 20, 2017 2:41 am

Does anyone have first hand information on 12'-14' mini's (aluminum not fiberglass) running Rotax 582's? Specifically, I'm curious how heavy your hulls were, how they pulled, where you ran, if you had a poly bottom or ran frog-spit, etc., what they could haul, and to see if anyone did any thrust tests with their set-ups. I just sold the 582 grey head on my 12' boat and trying to determine how much more HP I need vs want before I install the new engine and begin the redrive process. I live in Alaska and use my boat primary to hunt. Thanks in advance.

There are some videos on there of a mini i built for a fella , its running a kawisaki 440 which is around 40hp its 12' ran well with two and some dry with 1 , wind seemed to knock the stuffn out of her though, im not a mini advocate per say but it did suprise the hell out of me , we are doing the same hull with a 103hp geo metro engine and reduction next , i think i have full build pics stashed away somewhere if you want them ill have the wife try and upload them when we get back in town

I built a 6'x12' mini with a 503 dual carb rotax on a alum hull. It performs great, runs 40mph with two guys. I'm currently doing some changes to it. Overall I'm happy with it. Need anything let me know!
