Greetings All--
I have a '90 Montauk with a '99 Johnson 90HP. I do a lot of fishing in areas of the Pamilico Sound and need often need to pass through areas which are pretty shallow (~1-2ft or less). I love my Montauk, but I would like to get into these tighter waters...
I wonder if any of you have any experience / opinions / suggestions on this configuration? Also, does a normal (non-hydraulic) jackplate, set to the "optimal" position for a Montauk, significantly improve the engine draft, and if so, by about how much?
My thanks in advance for your help and your comments.
Cheers ---

With my manual javkplate I have my engine set about 3.5 inches off the bottom of the hull(plate). It rides great and gives me 3.5" less draft. Even with a power jack, you would only get another 2-3" rise. Not worth the $$ in my case but sometimes 2" is all it takes to make that shoal.

I have a CMC hydraulic jack plate on my '83 Montauk. Simply put....I LOVE IT. Jackplate is mounted flush with the transom and the motor is mounted in the lowest holes, which is its highest position. Still, with my Stingray tail on the cavitation plate, I can run the motor all the way up....and that is real shallow. You can't goose it or it will cavitate, but at modest throttle on a plane, you are running real skinny. When heading offshore, just lower it back down. You will love it.

Bigshot,
What brand and model non-hydraulic jackplate are you using? I want to put one on my 1973 Montauk. What is the setback from transom also. I am running a 90hp Yamaha with a 17 pitch prop, will I need a different prop also? Thanks for your help
