That prop looks identical to the 4 blade that I have.  The prx4 is a more aggressive looking prop

Got a good pic of 'er sitting in the water,  full of fuel and full cooler under the leaning post.  Ran awesome all day long with me and 2 other adults and associated crap and was getting just over 5mpg. 

Been having an issue with the reversing relay for the jackplate......  The switch input leads keep loosing contact inside the relay and it stops working,  I can move/hot-wire it to make it work but need to find a better solution.  I think the vibration from being mounted directly on the motor is breaking the connection loose

As a reference, I top out at 36 mph with an Etec 90 on my 175 with a 3 blade aluminum prop. I think you should be able to do better.

What RPMS are you getting at WOT and what size and pitch prop are you running?  I can get 38 MPH out of my 170 with a 90hp Ocean Pro.  I know a little more pitch would give me more top end If I wanted it.

It is very critical for the Etec to be propped right.  If you are over propped you will have problems with high exhaust temperatures and carbon build up.

I don't want to hijack his thread but I can hit 5k. The max rpm in the emm is like 5200. I suspect I could be slightly over propped but not a lot. 4500 to 5500 is recommended. My speed is GPS and would be effected by currents which can be strong where I go sometimes.

Basketcase... the optimum rpm range for the I3 90 is 5000-5200 rpm. The max wot rpm range is 5500. You could use 200 more rpm.

Looks great indeed.  How does she sit in the water?
