'Evening, Gentlemen-
I have what I believe may be a stupid sounding question, but bear with me. I'm in the process of restoring a '64 Mirrocraft runabout & have some questions about jack plates. The transom is approx 16", the motor is a 1965 Evinrude Big Twin 40hp. It is the original motor that came with the boat. The previous owner said the boat topped out at 20mph on gps, which seems very slow for this boat/motor (had a previous thread regarding this). It was suggested that perhaps the motor wasn't running as well as it should. I've been doing some reading on the differences in performance that motor height makes & have been doing a little research on jack plates (manual, not hydraulic/power plates). Here's my stupid question - the jack plates I was finding all seem to be set up to LOWER the motor, not raise it. Looking at the motor mounted on my boat, I think that the motor would need to be RAISED, if any adjustment was needed at all. Not much, possibly only by an inch or so. Do you guys know of any good manual jack plates that are for adjustments either up OR down? I was looking online at the Vance jack plates, they seem to be nice & are reasonably priced. However, if mounted even with the top of the transom, they would only move the motor DOWN FURTHER (unless I was misunderstanding the info given & pics of the product).
Thanks in advance for the help!
