Hey Silversurfer, We have been using the 35 HP Briggs. We get on plane easy and on ower hull we can run aprox. 32 miles
per hour. I know the Rotax will work good but they are expensive. We just got a 4A084 millitary generater engine in yesterday. It is 20 HP but we think we can get aprox 40 HP out of it. We are going to do a project boat to see how it
performs. It's good to see you posting again. Thanks, Chuck
I see a few 582 for sale with 2.58 to 1 gears may have to try this. have try this combo? Chuck have you found a way to get 2 hull and rigging out to utah? I got to have one of those mini alum hull.
Hey Silversurfer, I haven't tried a rotax yet, but with the power to weight ratio, it would perform really great. I will make
some calls tomorrow and try to get a handle on shipping. Thanks, Chuck
CAJUN has a rotax you might check with him to see if it is for sale
Rotax engines work very well on minis but yes, they can be expensive compared to a briggs or kohler.
Some Rotax options are:
Engines:
503 Dual Carb Single Ignition (Points Motor)= 52 HP
503 Dual Carb Dual Ignition (Electronic Ignition)= 52 HP
582 Blue Head (Water Cooled) = 64 HP
618 (Water Cooled) = approximately 75 HP
583 (Water Cooled) = 97 HP (High Performance motor)
Also available, but I'm not sure on these engine hp ratings: 277 | 377 | 447 | 532 | 912 | 914
Gear Reduction Drives:
B Box - 2.0:1, 2.24:1, 2.58:1
C Box - 2.62:1, 3.0:1, 3.47:1, 4.0:1
E Box - 2.62:1, 3.0:1, 3.47:1 (This gearbox has a starter mounted on it)
Note: From my own experience, I will never run another rotax without having a clutch installed.

Live life on the edge! It's less crowded and there's a much better view....
