Hi, twin 75 unless 2 stroke may be uderpowered unless the boat is run light. (training 1:3 you should be ok)
We run single 175hp and when heavily laden performance drops. (42knts to 39knts and slower whole shot)
Great to see a twin setup being used for training.
Overall a superb boat imo.
(We like ours so much we recently bought a second xs)
Hope that is of some help,
