I am getting ready to take on the project of replacing the transom on my GW Trophy 259. I noticed a cracking noise last time we were out, but one motor was loading up on 2 cylinders and missing at idle, and I thought that was just from the motor. When I was washing the boat down that evening, I saw that the transom was pulling past the cap. The cap was cracked when I bought the boat, but not spread out like in the pics. But I have several problems that I have to figure out. First is my Home Owners Associatian's permission to have my boat in my driveway for about a month. How I hate HOA's. The second problem is that my transom is wider than 8 feet, and taller than 4 feet. The third is that I am going to repower this winter and my transom is set up with 2 2.5L Sea Drives. The first problem can be handled. The second problem is my main concern. I have read and read here on the forums, and it is probably here somewhere and I haven?t found it. I don?t know what to do about splicing my transom. I can?t find 4? X 10? pressure treated plywood. I haven?t check on marine plywood though. The third dilemma is if I am going to repower this winter, now is the time to cut the transom to for the repower instead of mounting a twin motor bracket. I did some measuring today at storage. I lowered the trailer tongue so the bottom of the hull was level. Then I lowered both motors until the cavitation plates were level and took a straight edge and marked the hull in line with the cavitation plates. The motors are mounted 32 inches apart on center, and that was where the cavitations plates cleared the hull. That is 4 inches above the bottom of the hull. So I figure measure up either 29 inches or 34 inches from the bottom of the boat for the height of the motors. Is my thinking correct, or are there other ways to figure height of the transom. I need advise through this whole project and Iboats people have the experience. All ideas and thoughts are needed for this. Thanx.
