Charlie when you say tuner, did you dry stack your tuners ?

What do they do to them ? I had my dry stacked, they sound different, not sure if it really helped. I did to many changes at one time.

Right now Im replacing a lower, which gear ratio do you run 1:87 or 2:00 ? Im changing to 1:87 I heard they are stronger.

Charlie thanks.
The biggest gains I have found after props, is in learning how to drive the boat. These things are sure sensitive to trim settings. And moving the steering around to let the hull find its natural path. Has anybody tried any props bigger then 15''

Charlie did you have your rev limiter bumped ?

What props do you run with everyday and at what speeds ?

Charlie I am getting new 280's on a new 28 and I was wondering what setup you had to go 121 on stock 280 that is wild. Do you have your engines bolted right to your boat or to jack plates? I heard that jack plates can be a pain because you have to maintian them and they come loose. Also I was told to have water pickups in the hull so it is better. Is that correct? Trying to set it up right the first time so not as much tuning in after we get it in the water. Thanks

Skaterjim sent me a set of 15" plus diameter not really sure what they are,the blades almost hit my cavatation plate.I know he has good result.the weather hasn't been to good up here to check them out fully,they do give the boat a nice attitude.

the motors are on jack plate cmc, diamond marine modified them so you only need to use a wrench to adjust them on the outside.It takes me no more than 5 minutes for both motors.My jack plates have never gave me any problem.I don't use remote pick-ups.
