Seaducer 20 mono. 1996 version

[Steve Lawrence]

Hi
I have had this one unbuilt for a long time. I see that there are two positions shown in Seaducer instruction sheets for flex drive shaft placement. Looks like surface style ( right inside the bottom of the Vee). Or 3/8” below the vee. Which is best? Any motor recommendations?
Many thanks
Steve

older seaducers were sub surface drive, possibly yours. newer ones are surface drive. some tried surface drive on the sub surface hull with mixed results. call jerry at seaducer boats and see what hull you have. i have a 33'' ducer hull with a nova rossi 21 modded by brian sorgente and a shoboat 1614 prop, very fast mono

Thank you for the information. I will call them to determine which hull I have.

Yea I have two 95 21 seducers I believe they are first gen and they are meant for sub surface drives

That’ll be a sub surface hull, the strakes run right to the transom

I would run it surface drive. You won't be disappointed. I run mine that way. It's fast the thing about our boat is it won't handle rough water like the newer models. I choose my races to go to where I know the water will suit that boat. Calm water . I run mi e at st louis race in May. Not to worried about speed. It's rough water. Have fun

 

[David Bryant]

I'd set it up exactly as on the instructions, it will run very well

a guy i used to race with went from sub surface to surface drive with his 21 ducer, this was back in the day when 21 monos were doing 45mph. not sure how well it would run in todays speeds but it ran well back then

built my 21 seducer back in the day with a p5 pico surface drive showed up at the Orlando winter nats and show Gary Crowther he tells me it would not work till he saw it run 55 MPH heat racing mode don't waste your time running sub surface they all work surface
