sport 20 class

[KenOlvis]

I was wondering if a ski over the drive shaft can be used on the sport 20 hydro class.Before i even think of testing one, is it legal in NAMBA OR IMPBA

I don't think it's legal on a sport boat, only on riggers. This is due to it being an additional running surface aft of the sponson transom. Since a belly pan can't be below any running surface, I think the same would apply to a ski

Is a square strut legal?

Coolbeans thxs for the info

 

[FloridaScaleBoater]

Square strut is legal

[KenOlvis]

Whats the max width for a 20 hydro ?

Have any of you tried using an ammonia based cleaner ie: windex with ammonia or straight ammonia? Or a good strong detergent based cleaner to clean the outside case of the servos? Just a thought from an old experience in another life.

Thanks, John

It's not the hull that has a width restriction but the strut itself. I don't remember what that limit is, just that there is one

Look under the IMPBA rules on sport 20 and it has all the INFO you need.

 

[FloridaScaleBoater]

Using the rule book is a wonderful thing

 

[Bradley Maglinger]

A strut width no greater than 9/16 inch wide or a length longer than 3 inches may be mounted either under the hull or on the transom with the farthest end of the drive dog as measured from the transom not extending out more than 3-1/2 inches. (See Sport Hull drawing for clarification.)

Thanks for posting i did look in the rules.I found the same answer! Guess I could use a square tube instead of round to help get on strut surface?

Thxs Ken

I wouldn't think you would need all that to get the boat to ride on the strut. Just the right balance point and maybe some strut angle would work.

Probably not!! just looking at options to test.an see if any body is or has tried. Would be nice to have surface of strut parallel to bottom even when strut is angled. But again just thinking out side the box as the epoxy dries to sand.after applying cloth an epoxy gained 2oz its now at 1lb 1.4oz before sanding im thinking total weight will be about 2 lbs 9oz
Thxs for the imput sir

 

[KenOlvis]

Got some sanding done. I'm going to mock it up before I finished the surface to prime.

Motor modified OS Max 18 an strut fits nice an low!!!

Ken,

Did you ever get those Jeff Wohtl .062" wire drives in stock?

They would be great on a Sport 21 or a 12-Hydro.

Let Me Know Please?

I never reordered shafts from jeff yet. I had one shipped to Joe for the 2nd .12 PHANTOM II its on its way to me now.If you sent a 1515 prop it must be on that boat.

The 1515 I have with me now is Andy Brown's prop.I do remember doing a deal sorry about the delay.I'm going to order more shafts in Jan I can get 2 for you or pay pal funds for prop no problem just let me know.Also I haven't recieved a H7 for my .21 PHANTOM II Thank you for the reminder.

Ken,

I would rather have the shafts if possible?

2 - .062" X 3/16" stub shaft X 14.625" long.

How is the testing going on the Phantom-12 ?

Thanks,

Mark Sholund
