Rod - We must be encountering the same issues! I am in the process of replacing my tank also. Through this link, I just sent the specs for my tank to Speedy Tanks (Speedytanks.com) and they seem very reasonable with their price, turn around time, etc. Never had an issue with the steering or seat posts. I actually have a leaning post with rocket launchers. No problems with the drains, but I did replace the scuppers with new ones from West marine. Easy job. 10 Minutes to replace all four on the transom. Haven't had the boat in the water since the replacement, so I don't know how they will work. Someone on the forum stated that they felt the flappers bought from West Marine were too stiff to their liking, but i'll have to wait and see. Mine is powered by a 2001 Johnson 150. Well pleased with the performance. Keep in touch and good luck with the windshield search.
