Call him, 386-747-7652 you'll get through quicker, trust me I do his repair work on all brands of mudmotors. In fact he was here at the house last night picking up a rig I worked on.
Brian I started out with a 1432 pushed by a 6.5 (Robin) Mudbuddy Ultralight. Upgraded to a Tiger Prop for it and in the skinny I could run it just out of the water like a surface drive and get almost 15 mph lightly loaded. Your friend could get by with a 9hp ultralight. Or try to find one of the 6hp hyperpunks.
