ive got a 91 checkmate 28 ft maxxum. have 2 200 mercs with mild upgrades. 36 in set back including jack plates. have 15 in mids with low water pickup lowers. wondering what props, what height, what way to turn the props. any help would be great. getting tired of buying props and loosing money when they don't work and having to resell them

First thing I would do is go to a 20" mid on a 28' boat.

Ask wildman on this board he deals in Checkmate outboards and custom setup and rigging

sorry i meant 20 in mids

OK,

Thats better, what seems to be your problem?? What props are ypu running now, and at what RPM??

right now i just have a set of 25 pitch laser 2s on it. 6100 rpms and only 57 mph.

well, i bought a set of bravo one 24 pitch props. still no better. turning the props outwards and they slip just as bad as the last set. i am wondering if it has to do with the vents. maybe i should have bought a set of sterndrive props. i am running 3 3/4 inches under the hull. mercury says they are surface piercing props and ment for high drive height outboards.

Lower your motors, and try mirage plus, as for the vents, fill them up, til it wont plane, then step back 1 size.

just sold the mirages on ebay. i called checkmate today and got some good info from them. my hull and the 2800 obx are the same so they gave me some things to start with. real nice people there. they spent 10 minutes on the phone with me trying to help me with my setup and i wasn't even buying anything from them. thats what i call customer service...

Nice, so what did they have to say??
