Hello,One year later. I finally could purchase a Revolution4 propeller at a good price. It is in good shape and I asked my mechanic to replace the old Enertia 19 pitch with that Revolution. I asked also my mechanic to raise the engine two more holes. The engine is currently at three-holes-up from lo...

Re: Repowering 2000 Dauntless 18

Just keep in mind that the Mercury 150-HO engine is slightly heavier than the OptiMax 135-HP engine. You will gain some speed and acceleration from a standing start.

You mentioned, the boat rides high. Maybe a particular set-up can partially solve [the boat riding high].

Re: 2004 220 DAUNTLESS VERADO 225 Propeller

In 2007, the last year the Dauntless 220 was produced, it was offered with the optional Verado 225. With that engine, the factory supplied the Mercury REVOLUTION4 prop in 14-5/8 by 17-pitch. The test of Dauntless 220 performed by Boston Whaler was dated May 2004. At that time, the ENERTIA propeller...

Re: 2004 220 DAUNTLESS VERADO 225

Thanks Jim,

I've read the article and it seems that the most appropriate hub kit would be the Flo Torq SSR (not the HD nor the solid version). Those parts are easily available at affordable prices.
Now, I just have to chase for a used Rev4 in 17 pitch and resale my Enertia 19 pitch.
