Need a little help guys. Other than my Nordic, I own a 2004 Glastron GX 235. Its a 23 foot bowrider powered by a 5.7L volvo penta (350 chevy) and has a SX-M outdrive. I am running a 4 blade stainless prop on her now. Here comes the problem! Once i get out of the hole and plane out i can't trim up under full throttle. If i back the throttle back down about three quarters of the way i can trim up. It will trim down under full throttle if i am trimmed up though. Just sitting it trims up and down no porblem. I have bled and filled the trim reservoir and lines, replaced o-rings, and all the fuses and relays for the trim motor/pump. Last year, the trim pump blew the relays and i found out that the quick connects for the trim pump were corroded. To fix this i hardwired the pump in, removing the quick connects and crimping on new connectors and covering in heat shrink and waterproofing. I haven't been able to find anyone that knows how to fix this problem. The last thing i can think of is replacing the trim pump and thats about 700 bucks. Any thoughts?
