Guys, repowering with a 2023 Mercury 115hp 4 stroke series (non command thrust). Anyone have suggestions on prop? Engine height when install? And last, if I rehub a viper 14 3/4 x 17 I had from an etec, would it be suitable for the new Merc?

What is your typical load going to be?
Rigging the engine and prop selection is critical given the power.
Mount the engine 3 holes up, top bolt in the 4th hole down from the top.
It is worth the expense of a new hub for the Viper. Try it. Should target a WOT speed of 37-38 running light and solo.
I would also look at a 14.5 x 15 Enertia (not cheap)
