Mercury Propellers | Prop Selector


This link takes you to the mercury marine prop selection page...this is a GREAT utility for picking the right prop for your application.

Next Link is Turningpoint "Prop 101" Lots of great information and another selector. Thanks PanMan VA

Propellers 101

If you have any questions about it or picking a prop please ask...this is a great place to start though. It will get you in the right direction. Just follow the links and plug in your information.

There are WAY more props of course than the merc props but they are some of the best and with the newer hub setups can be used on most rigs. Correct propping is the biggest problem on most boats....people compensate with whale tales and foils...for the best performance of any boat...it must be propped right...ventilated right....and the engine set at the optimum height on the transom...all these things effect the way the boat handles, comes out of the hole, and top speed.

Hope this link helps you out...I will be adding others as we go along.

If you have any helpful links please post the url.

Super post, Scrapper. Some great information. I especially liked the youtube clip of the making of a prop.

Scrapper,

Thanks for takin' the time to put this together. I've just reviewed the sticky and am now going to get the replacement prop I need.

aj

Afew weeks ago i broke a fin off my prop. and broke the shaft inside the motor but luckly with some jb weld and a broken pool stick i was able to get the piece of the shaft i broke (how lucky was that) anyway i had another motor the same as my old johnson 50 and was able to take the lower unit off and replace it, but now i only have foward only ?????????? no netural or reverse could someone please help me out here, as soon as i start the boat is ready to take off.

Sounds like you didnt have the replacement unit and motor timed right when you re assembled it. Engine shift must have been lined up in fwd but not lower unit. Check with local repairer to verify...
