Hello everyone,

I currently have a Explorer 166 jet boat with a 90/65 yamaha jet outboard. The boat is 16.5 feet long with full UHMW. I am looking for some more power and load carrying abilities from the boat. It is currently running a 1919 D 4 blade stainless impeller but I am getting mixed reviews saying this is the incorrect impeller for a 90HP engine? Also wondering if there is anything else I can do on the motor side to bump up HP

Thanks
