i have a few questions, i read through 10 pages ish and did not seeing much relevant i figured id post my own. i did how ever find some neat stuff.
first i have a 95 400 that i bartered for a $600 boat i bought, ive ran it for 2 years not doing anything but light service. full snorkeled, and i was told a spool or some sort of permanent locker. i havent confirmed that yet. a little bit ago it stopped shifting into second or higher, revense neutral and 1st all day long. after some research i see that bolt #28 might be backed out causing my problem. i took the front cover off and nothing seems to be wrong there, pretty sure i have to pull the rear cover off.

so since im going to be in there. was wondering on a whole what were the best or most popular mods? my readings found me the warn 424 kit which i would love, but i read someones post that the shaft length isnt available for the 400? can somone confirm or deny this. if it is true is there any way to get it to work. i feel that the throttle response and power would make it fun enough for me not to think of buying a new quad. ive read about using the clutch basket and final gear off a 300, but that guy was swapping in the 450 jug and piston. not sure what the gear change does to top end versus the low end gain on a 400? thoughts??
