I felt like 40 was obtainable ? Do you really think it's not. I'm already at 34 turning 5500-5600 rpms. I felt like the jack plate would give me the rpms to turn a 14P.

I think its obtainable for you but that's gonna be the max I would expect anything more. But like I said I'd focus more on setback first

You are at 1% prop slip now with the 13 if your numbers are right. You will have to turn a 14p 6100 rpm to get 40 mph.

Miller and Mearle what is your setup?

I like the idea of the breakaway plate, however I would like to be able to keep my holeshot that I currently have. If I go with a breakaway plate which keeps the motor at a set height won't it increase my time to get on plane? Also would this make the boat porpoise ?

1648 Tracker Grizzly, 97 40 2 stroke yamaha bone stock, 14p vengence prop.

I have my jack plate set pretty high by most peoples standards. I had no problems running in the swamp w/ no breakaway at the poker run. Since I'm set at the height I am, when I trimmed up, the bottom of the motor sat higher than the bottom of the boat.

I got an edge 550 with Yamaha f40. Power tilt/trim mounted on a breakaway plate. I'm turning a power tech reb3 15 pitch. The breakaway plate didn't affect my hole shot at all

Triming up forces the stern down. Thus initiating porpoising. Jacking the motor up pushes level. Thus not initiating porpoising.

Thanks. So should I be able to get enough height out of a breakaway. I know its hard to determine without being able to see it.

If mounted right yes you should be able to clear the bottom of the hull. If not you'll be in the same boat I'm in and need to get a plate made to raise it up.

How many rpm are you turning? What is the rev limiter on those 4 strokes and can you cut the limiter wire on those like you can the 2 stroke yamahas ?
