Ok... you guys helped me out alot with a problem i was having last year.. i have an 1989 Johnson GT200 that is on a 1989 Basscat Pantera II, 6"CMC Jackplate, propshaft 3 1/4" below the pad. I had a problem with the top end.. no matter what prop i threw on the boat i could not get the rpm's above like 4400-4500. I took it to a local shop after finding a half decent shop in my area. He found a bunch of small things that contributed to a bigger problem such as loose carb bolts, a fouled out plug and some other small things. motor runs much better now i can get about 5400 out of it... however i still think there is a problem there.. I bought a 25 tempest off ebay and sent it to mark croxton to get worked, he called me and said the blades were 1" shorter than what they should have been. So i bought a brand new tempest... whatever i do i can not get this boat to plane out with this prop.. its weird... if i set the pvs plugs to vent at 3500rpms like they say you should when it starts to lay over it cavs, or even beforeit lays over sometimes. the only way i can get this thing on plane is to load the prop up with like 1 solid and 2 small... and then the holeshot is about 20 seconds. horrible. the max rpms i got out of this prop was 5000 and 58mph and mark said this motor shouldbe able to turn that prop 5800-6000 easy. so mark and i are still puzzled and he sends me a 23p shooter or something.. a 4 blade anyway. This prop i can turn 5400rpms 56mph and this is the puzzling part... if im running a 25tempest 5000 that 23 shoudl put the rpms through the roof... with all these props i have very littlebow lift also... i hope someone can help.... im really getting frustrated with this motor.. if it wasnt so far and had the time id take it to rusty because then i know it would be checked the right wayl.... but im in pennsylvania and hes in tn... its hard to leave my job for that long..


Thanks to all that are helping
