Need prop help for 28hp Evinrude

[Wkoch]

Hello,<br />Hoping somebody outhere with a manual can help me out. I have an '87 28HP SPL Evinrude. E28ECLCUC I need to purchase a new prop for it. It is on a 16' Aluminum Bass boat.<br />Trying to figure out what size prop I need. The darn thing that is on there now looks like a tiny 7' prop. Everywhere I have looked they recommend a 9". As far as pitch goes I think I will go with a standard work type prop.<br /><br />Any help wold be great!<br />DeadPaisly@hotmail.com

According to the OMC propeller selector guide your rig will either require a 10 1/2 X 12(p/n 380637) or a 10 1/2 X 13 (384460)prop.These are aluminum props.There is also a 10 3/8 X 15 available.<br />Your final selection should be based on the one that will allow your engine to operate within the factorys recommended rpms at WOT.<br />I recommend use of OMC propellers for your engine ,however there are some other manufaturers props that will cross reference.

Wkoch<br />OB is correct about finding the WOT for the correct pitch. I have a 89' 28HP and I would suggest you start with the 12" pitch. A 9" will definitly over-rev the engine. You can always get a prop shop to take it up or down 2 inches in pitch to fine tune it if nessesary. That will effectively give you a range from 10" in pitch to 14" in pitch to play with.

Rickdboat, I have a 1990 28 spl and am going to change the impeller. Never did one before what am I up against. What parts and gaskets?<br /><br />I know this is off the subject.<br /><br />-----------------<br />Flahthead

Flahthead <br />Dropping the lower unit on that motor is a breeze. If you have the Manual and the pump kit(Below), you should be done in a couple of hours. No surprises or anything like that.<br /> web page

Rick is correct .9" not 10 ".I was looking at the wrong prop list for the older 28 hp.
