IM31 strut or MG29 strut?

[NorCalZ71]

Converting a blackjack26 to strut and offset rudder.. is there any difference between the Im31 strut and the geico strut? I'm getting an impulse 31 flex from a friend and I'm just curious if I can use the mg strut? mainly because it comes with mounting brackets.

Check Out BJ26-v2 Parts

Kevin,
Are you wanting to do the conversion because your boat came with the steerable outdrive??

If yes, on the BJ26 v2 boats - they're called: "Blackjack 26 SS BL Catamaran 2.4 RTR" - PB replaced the outdrive with an offset rudder and strut. Go here... http://www.proboatmodels.com/Product...rodID=PRB3300S - and check the parts list, I attached a pic of the transom I got from that page.

I checked HH, those parts are still available...

Using those factory parts would probably be the easiest way to make the conversion, prices are about on par with aftermarket stuff, and those parts made for the exact model of boat you have so you don't have to Mickey Mouse anything.

Just some food for thought...

Yea 2 of my friends went that route. I don't like the 1/8th inch shaft and set screw on the flex so I decided to go with a one piece shaft from the newer models..
