Prop pitch for ETEC 90 hp

Post by Phil P »

Next week I am installing the ETEC 90 and I need to choose a prop. I have searched this site and browsed you-tube for information.

I have read that a 11 or 13 are good on this engine and I've seen videos of 15's on the 90 HP suzuki. Can I go with a 15 prop pitch with the ETEC 90?

Check the gear ratio of the Suzi 90--if its the same as the e-tec, then the 15 will most likely be OK.

Hi Phil
We have just put a 90 etec and wedge on our M the first prop was a 13 3/4 by 13 we only acheived 4300/4500rpm at sea level 33km ph ballast in + 4 people WOT
We have now bought a Amita 3 14/9 solas alloy (part no 2411-140-09 ) with the option to re pitch it if we can't acheive 5500rpm WOT
Haven't tried it yet waiting for a warm day
hope this helps
Cheers

Hi phil
Got your email
I have a 11 13 and 15
I have found the 15 is the best overall
The 11 will snap everyone back back in their seats toot sweet
So good for water skiing
But the 15 has the best top speed and fuel econ
You can run 3500 rpm going 20kts for hours.

I bought a 13-1/4 x 17 & still have to try it yet hoping to do better than "beene" with fuel economy & speed :)
