    Default am phibian

    Hello Greg: i am totally new to jet drives. i was told by california marine in vancouver B.C. that the american turbine i have should drive a 5000LB. 20 ft aluminium hull( like boston whaler or old sea sled hull)up on a plane with a 35o chev with a shorty power glide i hope. what i need is data on installing cooling etc.my hull mount /pickup seems to be OK . there is two fins on bottom of intake plate, can i delete / do i need a screen on intake?

    Rick, When it comes to plumbing a jet boat you can take water right off the pump. Are running in salt water? If so you can do a fresh water cooling system. The fins are there for 2 reasons , first they enable you to track straight and secondly the help in carving a turn. Do you run in shallow water? The fins can be removed if you are running in shallow water ,but be careful in turning it will act like the boat want to swap ends. I would think you would want some sort of protection so a stock rock grate should be fine.
