Another Prop question (20 sf)

Glad to hear your dealer is helpful. Hopefully the shape is right - the new SST II has more cupping than the old but as Bushwacker pointed, out that 115 has a lot of guts and should spin it up to target. Good luck and Keep us posted on your results. Enjoy the holiday.

Thanks again Gilly and Bush,


Ran my 115 E-TEC with a 13 X 15 SST yesterday vs. the 15 Viper that came with the engine...both as a singleton and with 5 grown adults (and full 45 gals of fuel).
Results were:
NO problem spinning up to 5500 rpm at WOT
Faster out of the hole
Easier steering at top bend (I had another thread on this steering issue)
Engine clearly not laboring as the Viper was to keep it at 4800 rpm's
Only thing I am giving up is 2 to 3 knots at top end. Was able to do 26.2 kts GPS vs 28.5 kts (with Viper)...which is fine by me.

Soooo....unless there are other thoughts, looks like I will stay with the SST.

Thanks!

Sounds like a good fit.

Glad you got out. Did you get around to checking the height of your anti-cavitation plate relative to the keel?

I didn't think you'd lose 2kts. That being said, the more significant performance issues are improved.

Enjoy. Check that mentioned height with the plate and keel parallel. I'd be interested to document that...

Thanks,


I am on the 2 hole and will check out the cav plate position as soon as I can get another driver.
