Can someone tell me the approximate prop shaft height to start
trying for an sst 60 for a river toy. I don't intend on racing except for fun

prop shaft 1" below pad for v-bottom
Tunnel? depends on prop dia, and how good what is your setup
Boat is a lee tunnel with center pod I know absolutly nothing about it as far as rigging I just wanna go fast
you gonna drag or top end
It's just an old marsh motor I took off of an 1842 tunnel

If you ONLY want straight-a-way speed, Mount the motor so that the bottom of the gearcase is just touching the water,when on plane . ..you have to be sure you'll get enough water to cool the engine . You may have to put on a "nosecone" with an underneath water pickup .then get a 3 or 4 blade cleaver propellor, with much more pitch than usual. Then your boat may not want to turn, without a rollover, but it might go like a rocket . My did (it was a "sport E" tunnel, back in the late 1970's.)It was powered by a Rude 1975 short shaft HUSTLER (75 horsepower).
Thanks for all the help. I'll try to post some pics tomorrow if I can figure out how. I'm cutting the transom down 4 inches right now because it was built for a 20 inch motor
I forgot to mention; from the top of the transom to the bottom of the tunnel, the height (was) on my boat 24"-that's what it needs to run free- no drag from the gearcase.For TOP speed- about 24-25" pitch prop. in those days a DAH reworked OMC race prop was about the fastest.In fact- we liked to use the large diameter prop OMC made for the 135 h.p. V-4.
(same spline as the 3 cylinder)
