Would love to see a picture of your boat. I have a 94 2320 with extended cabin. Yamaha f300. Curious what makes it a 2330 vs 2320?
BTW I had the wet corners too. Went to duckbills & fixed that but they let very little water out. Going to try the TH balls Warthog recommended. Parker tech once...
Wait until it looks like mangy donkey fur & smells like roadkill. I couldn't take it anymore. My '94 looks so much cleaner inside now but it was definitely not a fun project.
There are threaded bolds embedded into the floor. I installed my Pro-pedestal with no problem. Getting the screws out was mostly easy. A couple of them were stuck so borrowed a larger impact driver.
No twist at all. That aluminum plate doesn't flex at all. Just the pulpit up & down 1/4 inch in heavy seas. The 1-inch starboard the entire length of the top will definitely fix it.
Mine is solid but with the anchor, the Minn Kota & the 40-pound plate that the MK sits on it flexes too much in rough seas. I am thru-bolting a one-inch thick piece of anti-skid starboard on top of it this spring.
