What is the advantage of the stainless vs alum drag plate? do the aluminum ones bend ? this is to try and help planing easier/quicker with a load, with 4 on board and 24 gallons of fuel i have to make the back seat passengers move forward, i have been thinking about trying one for awhile Thanks |

yep yep , get one . I'd get just .090'' with the bend on the outer edge to keep the bending to a minimum . |

I think aluminum will bend like crazy.... And probably eventually crack. I know what I would go with... lol. |

It's all about metallurgy and material, Jeremy. Industrial grade aluminum you can almost bend in your hand. Same goes for certain grades of SS. Material grade and hardening are engineering factors that must be considered. For a lake boat, I would recommend stainless. Full on drag boat, titanium. Flat plate on a combination boat, 6061 T6 aluminum or stainless would work fine. You can't successfully bend T6 aluminum. If you want a bent plate go with stainless or 3000 series aluminum. Mitchies plates work well also. Made out of "plastic". A whole other world of engineering. Cloud it up enough for you?!?! |

My new ones are glass..... The plastic would get too brittle over time and exposure to chemicals. These things undergo a HUGE amount of stress. |

I just happened to have my "plastic" Mitchie plate last weekend at the tri lakes run we did, showed it to a couple guys. Still looks as good as the day it was mailed to me, but I've taken care to keep it clean and chemical free. |

Steel is 3x Stronger than aluminum, this does not mean the aluminum is no good, providing a stiffener like Jeff said in good practice. 6061-T6 has good tensile properties so it would take some to bend it and I would agree it would work fine. |

All I have ever used is AL ones and always held up for me. Simple to make and cheap ...... buy the AL , make the template you want out of bristol board and away you go. As mentioned I have used .090" or .120'' and with the correct bend to add the strength it will be more than you need... Simple for a guy like you. Find a metal break and design it so that you can have a nice 45* bend at each sides outer edge to be parallel with the propshaft ... done Bolt it on with 6-8 10/32 SS bolts/washer/nuts Or buy any one you choose. Either way it WILL make an improvement |
