You end up with 2 screamin' big blocks getting passed by bowriders and you are using 3 times the fuel.

I havnt seen a twin jet until I came across this one. Ive seen twin jet 1 motor setups on you tube. These jets are mounted on berk angled suction housings blended into both of the v with the transom plates as seen on single installs. Spaced wider than outdrives. Re power.... 350 stroker kits are reasonably priced today. With an aluminum intake and nicson logs, predator carb. It should boogie. Looks like a jc pump with top steering with sainless tie bar with anode. Thanks for the input.

Jc pumps will be an improvement over the f pumps I dealt with .no cavitation ,no bowriders coming close to running by. I have videos .
