|
|
Hi,
I'm looking to get a spare prop for my Suzuki DF175 on my Venture 26. Right now it is spinning a stainless steel 15.25 X 19R, which works perfectly where I have been running it (about 900ft above sea level). I get right up around 6000rpm full throttle.
I've heard some folks having trouble if they go to higher elevation like Lake Powell, although not with this specific boat/motor combination. I may be looking at taking this boat to Lake Powell next year. I was thinking of getting an aluminum spare prop that is pitched down a bit from the one I am running right now, specifically for these conditions. But, I don't know if that is necessary, and maybe I should just get one with the same diameter and pitch that I have now.
Any input / advice welcomed. Thanks,
Mathias |

I can offer what I've done with a Honda 90. For most boating, I use a stainless 15 pitch prop. At Lake Powell, I use a 13 pitch, which lets me get back close to proper RPMs. _________________ "And in the end, it's not the years in your life that count.

As Steve notes most of us with the Honda 90's on the 22's drop to 13" pitch. I also tried this with my C Dory 25, and eventually went to a 11".
The Suzuki 150 and 175 are the same block etc--and you can drop 2" to a 17" pitch and be fine. The aluminum prop will have a little more flex, than the SS--and the SS is preferable for most running. However, all boats need a spare prop--and the Al, in 17 pitch would work well. _________________ Bob Austin

Excellent - thanks guys. I will try to find a prop that is a couple inches less pitch than I am running now. |
