500 efi wiring/ trim tabs
 

Hello everyone, We have a 1998 500 efi and i"m trying to find the boat harness to match the engine harness. We have a 91 chaparelle 2550 sx sport that came with a 7.4. Although the plug ins match, its not right and want it right. also This boat is a tank and weighs 5000lbs dry weight. We cant install trim tabs on the outside of transum because it has a notched swim platform that limits the mounting surface on the outside. I realize we could mount closer to outdrive but don't know if it will affect performance. Found some i think would work from eddie marine called Sponson tabs pt # 500-90b. but they don't list any specs for them on there web site. And getting anyone to respond there is like pulling teeth. Help
