Well isn't that interesting. Hmm.1974 or 76 I cant remember. Splash of a Tahiti. He has owned it since new. We are dealing with exactly what you are explaining since he put the new(to him) motor on. I finally convinced him to order a jackplate. It starts to lift the transom at about 55-60mph and starts to chime walk. Motor needs to come up about 4"-5" and it will be a 90mph boat(if your willing to drive it).
And that's exactly why I came here. Listen I'm not trying to ignore everyone and say everyone is wrong. I raised the motor another 1/4" but I have to wait another 2 weeks to test. I would love to test it every day, and update the thread more often, but I can't. And I would love to all of a sudden end up 6" higher than I am now and be at 70 mph. It's going to take me months, though. I'm working though it, baby steps.And just to let you know.. you are not getting the "thousands of google" responses on here. You are getting "real world" advice from some of the "best in the industry"(besides me, I'm still a sponge with these guys)!! And most are talking from experience.
I figured maybe I had a special case that went against all the common rules of thumb for this sort of stuff and if I documented it, tested, tuned, documented and ended up with a solution in the end maybe I could learn and share my findings with others, too. Listen, if I raise this motor 6" and it goes 20 mph, what did we learn?Why ask for "help" if you are going to contradict the options!?
In my OP "Interesting conversation/observation even if nobody has any input."
My original plan when I bought the boat was the RAISE the motor. I was like "damn, that looks pretty low." Then I pick up 10 mph lowering it, so it's a major WTF moment. It doesn't make sense to me either.
