My dad had a 1960 17' Thompson and a 40 Evinrude then upped it to a new 75 Evinrude in 1963 and a blistering 33 mph DAYam!
You're right...those were the days
Actually I taught myself ,along with physics101 and a USPS course somewhere along the way.
The ramp I use has a nasty tide running one way or the other almost constantly. Its on the outside of a bend and I have amazed a few people comming in there.
