|
|
Hi All,
For a simpleton like myself who can't afford the Hamilton 212 and we are only talking about a 20 ft. boat. Also other pumps like the AT 312 and or the 309 would definitely be an option also.
Boating the local lakes and the Fraser and Harrison River during salmon runs / sturgeon. No more that 4 big guys in the boat.
Form you expert, since I have been a prop guy for all of my life which one would be your choice between the options listed?
PS I can't afford the Scott either.
Thanks
Marc |

The American Turbine SD309 works best in a 12 to 18 degree v bottom boat;best for lighter and higher speed boats;Stainless impeller and Hi thrust reverse are options.
The KODIAK 3 stage is an exact copy of the old Hamilton 3 stage;works well in 4-8 degree boats;stainless impellers and hi thrust reverse std;excellent in whitewater,best pump for eating sticks and debris (even better than a 212) and for pulling power at lower speed. |

Another option you can look at is a 2 or 3 stage Flo Pro sold and distributed by Exact Welding in Prince George. Flo Pro comes std with SS stator vains, HD duplex SS impellers, oil bath bearing, insertable posi-nozzle and a SDR reverse bucket. Depending what power plant your going to install and don't want excessive pump stick out pass the transom. You may want to look at a 2 stage with a three blade 19* pro lead impeller a trailing 27* 4 blade with a 92mm nozzle insert will handle 350 to 360hp. The 3 stage will handle up to 500hp with the right impeller combination and nozzle insert. |

Thank-you gents.
Is the reason you're mentioning the two stage is due to no clean out in both pumps and a stick passing by the transom would be a pain to remove in a three stage?
Is the clean out feature used much on the Xtreme or Kodiak pump?
Did Proflo pump thought the clean out not to be necessary?
Would a stump clean out grate stop the problem sticks getting inside the impeller chamber?
I do like the improvements on the Proflo pumps compared to the Kodiak and Xtreme.
Please keep the information coming, I need to be informed.
Sorry for all the dumb questions.
Thanks

No the cleanout on the 2 stage or 3 stage pumps are located inside the boat. A 2 stage has one less stator and impeller making the pump shorter the a 3 stage. Normally you don't require a clean out the multi-stage pumps pass debri fairly well unless you pick up a rope it will not go through the pump. With Flo Pro having no clean out cavity gives better water flow through the intake. I would say that's why they eliminated the clean out in their pumps Yes a stomp grate dose help clean out debri or small stones caught up in the intake grill causing cavitation. |
